METHODS: The serum zinc levels were measured in 329 patients post-pancreatic surgery between January and April 2021. The postoperative serum zinc levels and clinicopathological variables were retrospectively analyzed. RESULTS: The median serum zinc level was 73 µg/dL (33-218). Zinc deficiency (zinc level < 60 µg/dL) was observed in 52 patients (16%). A total of 329 patients were classified into zinc-deficient (n = 52) and non-deficient (zinc ≥ 60 µg/dL, n = 277) groups. A univariate analysis revealed significant differences in sex, postoperative body mass index, serum albumin, total cholesterol, creatinine, aspartate aminotransferase (AST), HbA1c levels, diabetes, surgical procedures, and operative blood loss. According to a multivariate analysis, male sex [odds ratio (OR) 3.70; 95% confidence interval (CI) 1.67-8.20; p = 0.001], postoperative serum albumin levels < 3.9 g/dL (OR 6.39; 95% CI 3.30-12.37; p < 0.001), postoperative serum AST ≥ 51 U/L (OR, 4.6; 95% CI 0.07-0.29; p < 0.001), and total pancreatectomy (OR 3.68; 95% CI 1.37-9.85; p = 0.009) were found to be independent predictors of zinc deficiency after pancreatic surgery. CONCLUSIONS: Zinc deficiency frequently occurs in patients undergoing pancreatic surgery. Lower postoperative zinc levels could be linked to sex, the serum albumin and AST levels, and surgery type.

INTRODUCTION: Immunotherapy is becoming a promising approach for unresectable-hepatocellular carcinoma (HCC); the anti-tumor response is affected by the tumor microenvironment (TME). Although Wnt/β-catenin mutations are reported to cause non-inflamed phenotype, their role on TME remains controversial. We aimed to clarify the heterogeneity of immunophenotype in HCC with Wnt/β-catenin mutations. METHODS: This study includes 152 resected HCCs; mutations in the catenin beta-1, adenomatous polyposis coli, or AXIN1, or AXIN2 genes were defined as Wnt/β-catenin mutations. With hierarchical cluster analyses, TME was classified into inflamed or non-inflamed classes based on the gene expressions associated with T-cell activation. Expression profiles of molecules related to cell differentiation and biliary-stem cell markers were compared between the TME classes to investigate whether differences in tumor traits were associated with TME. RESULTS: Forty of 152 (26.3%) HCCs carried the Wnt/β-catenin mutations. Of these, 33 were classified as non-inflamed (33/40, 82.5%) and 7 as inflamed (7/40, 17.5%). Non-inflamed class was characterized by low number of CD3+, CD4+, and CD8+ cells on immunostaining, and high mRNA expressions of AXIN2 and GLUL, which are involved in the canonical Wnt/β-catenin signaling and hepatocyte differentiation, respectively. Non-inflamed tumors showed higher enhancement on the hepatobiliary-phase of gadolinium-ethoxybenzyl-diethylenetriamine (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) compared to inflamed tumors. HCCs classified as inflamed class are revealed to have high numbers of CD3+, CD4+, and CD8+ tumor infiltrating lymphocytes on immunostaining. This class is associated with increased expression of anti-epithelial cell adhesion molecule and FOXM1 accompanied by upregulation of genes related to interferon-gamma signaling, dendritic cell migration, regulatory T cells, and myeloid-derived suppressor cell activation and recognized as low enhancement nodule on Gd-EOB-DTPA-enhanced MRI. CONCLUSION: Heterogeneity of tumor traits and TME was observed in HCC with Wnt/β-catenin mutation. The potential was indicated that tumor traits and TME are determined not only by the activation of the HNF4A but also by FOXM1, both of which are downstream transcription factor of the Wnt/β-catenin signaling pathway. - Terufumi Yoshida; Kazuko Sakai; Masaki Kaibori; Mitsuaki Ishida; Shogo Tanaka; Shoji Kubo; Takuya Nakai; Marco De Velasco; Hideyuki Matsushima; Koji Tsuta; Mitsugu Sekimoto; Kazuto NishioOncology Letters Spandidos Publications 27 (3) 1792-1074 2024/01

We aimed to establish biomarkers that could predict prognosis, and formulate a simple classification using non-invasive preoperative blood test data. METHODS: We retrospectively identified 305 patients for a discovery cohort who had undergone HCC-related hepatectomy at four Japanese university hospitals between January 1, 2011 and December 31, 2013. Preoperative blood test parameter optimal cut-off values were determined using receiver operating characteristic curve analysis. Cox uni- and multivariate analyses were used to determine independent prognostic factors. Risk classifications were established using classification and regression tree (CART) analysis. Validation was performed with 267 patients from three other hospitals. RESULTS: In multivariate analysis, α-fetoprotein (AFP, p < 0.001), protein induced by vitamin K absence or antagonist-II (PIVKA-II, p = 0.006), and C-reactive protein (CRP, p < 0.001) were independent prognostic factors for overall survival (OS). AFP (p = 0.007), total bilirubin (p = 0.001), and CRP (p = 0.003) were independent recurrent risk factors for recurrence-free survival (RFS). CART analysis results formed OS (CRP, AFP, and albumin) and RFS (PIVKA-II, CRP, and total bilirubin) decision trees, based on machine learning using preoperative serum markers, with three risk classifications. Five-year OS (low risk, 80.0%; moderate risk, 56.3%; high risk, 25.2%; p < 0.001) and RFS (low risk, 43.4%; moderate risk, 30.8%; high risk, 16.6%; p < 0.001) risks differed significantly. These classifications also stratified OS and RFS risk in the validation cohort. CONCLUSION: Three simple risk classifications using preoperative non-invasive prognostic factors could predict prognosis.

In this study, we examined the relationship between the pancreatic volume and exocrine and endocrine functions after total gastrectomy. METHODS: The pancreatic volumes of 18 distal gastrectomy and 15 total gastrectomy patients were retrospectively measured using computed tomography volumetry up to 5 years postoperatively. Ten low anterior resection patients were selected as controls. In addition, the pancreatic volume and exocrine function evaluated by fecal elastase and the insulin secretory function evaluated by glucagon tolerance testing were prospectively examined before and one year after surgery in nine cases of total gastrectomy. RESULTS: After low anterior resection, the pancreatic volume did not change, but after distal and total gastrectomy, the pancreatic volume decreased continuously until the fifth year. After total gastrectomy, fecal elastase decreased significantly from 865.8 μg/g to 603.2 μg/g in the first year (p = 0.0316), and the insulin secretion capacity also decreased significantly from 3.83 ng/mL to 2.26 ng/mL (p = 0.0019). CONCLUSIONS: The pancreatic volume decreases continuously after gastrectomy for gastric cancer, and the pancreatic exocrine and endocrine functions decrease along with pancreatic atrophy after total gastrectomy.

OBJECTIVE: This multicenter study aimed to compare the short- and long-term outcomes of laparoscopic (LRLR) versus open repeat liver resection (ORLR) for recurrent hepatocellular carcinoma (HCC) using propensity score matching (PSM). Despite the expanding indications for laparoscopic liver resection, limited data regarding the outcomes of LRLR have previously been reported. METHODS: This study included patients who underwent repeat liver resection for recurrent HCC. Patients were divided into the LRLR and ORLR groups, and their short- and long-term outcomes were compared via PSM. RESULTS: There were 256 and 130 patients in the ORLR and LRLR groups, respectively. After PSM, 64 patients were included in each group. Intraoperative blood loss was significantly less in LRLR than in ORLR (56 vs 208 ml, P < .001). Postoperative complications of Clavien-Dindo IIIa or more were significantly less in LRLR than in ORLR (3.1% vs 15.6%, P = .030). The length of hospital stay was notably shorter in LRLR than in ORLR (9 vs 12 days, P < .001). Survival rates after repeat liver resection at 1, 3, and 5 years, respectively, were comparable at 93.4%, 81.9%, and 63.5% for ORLR and at 94.8%, 80.7%, and 67.3% for LRLR (P = .623). Subgroup analysis of patients who underwent wedge resection in repeat liver resection revealed that the postoperative complication rate was notably lower in LRLR than in ORLR (7.2% vs 21.8%, P = .030). CONCLUSION: LRLR for recurrent HCC is a viable option due to its better short-term outcomes and comparable long-term outcomes compared to ORLR. - Hiroji Shinkawa; Fumitoshi Hirokawa; Masaki Kaibori; Daijiro Kabata; Takeo Nomi; Masaki Ueno; Hisashi Ikoma; Takuya Nakai; Hiroya Iida; Shogo Tanaka; Koji Komeda; Hisashi Kosaka; Daisuke Hokuto; Shinya Hayami; Ryo Morimura; Masataka Matsumoto; Hiromitsu Maehira; Shigekazu Takemura; Shoji KuboSurgery 171 (5) 1311 - 1319 2022/05 [Refereed]
BACKGROUND: Laparoscopic liver resection for hepatic lesions is increasingly performed worldwide. However, parenchyma-sparing laparoscopic liver resection for hepatic lesions in the right posterosuperior segments is very technically demanding. This study aimed to compare postoperative outcomes between patients undergoing laparoscopic liver resection and open liver resection for hepatic lesions in the right posterosuperior segments. METHODS: In total, 617 patients who underwent liver resection of hepatic lesions in the right posterosuperior segments (segment Ⅶ or Ⅷ) at 8 centers were included in this study. We lessened the impact of confounders through propensity score matching, inverse probability weighting, and double/debiased machine learning estimations. RESULTS: After matching and weighting, the imbalance between the 2 groups significantly decreased. Compared with open liver resection, laparoscopic liver resection was associated with a lower volume of intraoperative blood loss and incidence of postoperative complications in the matched and weighted cohorts. After surgery, the incidence of pulmonary complication and cardiac disease was lower in the laparoscopic liver resection group than in the open liver resection group in both the matched and weighted cohorts. The odds ratios of laparoscopic liver resection for postoperative complications in the matched and weighted cohorts were 0.49 (95% confidence interval, 0.29-0.83) and 0.40 (95% confidence interval, 0.25%-0.64%), respectively. The double/debiased machine learning risk difference estimator for postoperative complications of laparoscopic liver resection was -19.8% (95% confidence interval, -26.8% to -13.4%). CONCLUSION: Parenchyma-sparing laparoscopic liver resection for hepatic lesions in the right posterosuperior segments had clinical benefits, including lower volume of intraoperative blood loss and incidence of postoperative complications. - Yasuo Otsuka; Ken Kamata; Tomoko Hyodo; Takaaki Chikugo; Akane Hara; Hidekazu Tanaka; Tomoe Yoshikawa; Rei Ishikawa; Ayana Okamoto; Tomohiro Yamazaki; Atsushi Nakai; Shunsuke Omoto; Kosuke Minaga; Kentaro Yamao; Mamoru Takenaka; Yasutaka Chiba; Tomohiro Watanabe; Takuya Nakai; Ippei Matsumoto; Yoshifumi Takeyama; Masatoshi KudoSurgical endoscopy 36 (5) 3254 - 3260 2022/05BACKGROUND: The value of contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) for T-staging in patients with extrahepatic bile duct cancer was evaluated. METHODS: This single-center, retrospective study included consecutive patients with extrahepatic bile duct cancer who underwent surgical resection after preoperative EUS, CH-EUS, and contrast-enhanced CT (CE-CT) examinations between June 2014 and August 2017. The capacity of these modalities for T-staging of extrahepatic bile duct cancer was evaluated by assessing invasion beyond the biliary wall into the surrounding tissue, gallbladder, liver, pancreas, duodenum, portal vein system (portal vein and/or superior mesenteric vein), inferior vena cava, and hepatic arteries (proper hepatic artery, right. and/or left. hepatic artery). Blind reading of EUS, CH-EUS, and CE-CT images was performed by two expert reviewers each. RESULTS: 38 patients were eligible for analysis, of which eight had perihilar bile duct cancer and 30 had distal bile duct cancer. Postoperative T-staging was T1 in 6, T2 in 16, and T3 in 16 cases. CH-EUS was superior to CE-CT for diagnosing invasion beyond the biliary wall into surrounding tissue (92.1% vs. 45.9%, P = 0.0002); the ability to detect invasion to other organs did not differ significantly between the two modalities. The accuracy of CH-EUS for T-staging of tumors was better than that of CE-CT (73.7% vs. 39.5%, P = 0.0059). CH-EUS tended to have a better accuracy than EUS for the diagnosis of invasion beyond the biliary wall into the surrounding tissue (92.1% vs. 78.9%, P = 0.074) and T-staging (73.7% vs. 60.5%, P = 0.074). CONCLUSION: CH-EUS is useful for T-staging of extra hepatic bile duct cancer, especially in terms of invasion beyond the biliary wall into the surrounding tissue.

BACKGROUND: This study aimed to determine the risk factors for severe postoperative complications in patients undergoing pure laparoscopic liver resection (LLR) for tumors in the right posterosuperior (PS) segments. METHODS: The study included 289 patients who underwent parenchyma-sparing pure LLR for tumors in the right PS segments at eight treatment centers between January 2009 and December 2019. RESULTS: Multivariate analysis revealed tumor size ≥3 cm (P = .016), segmentectomy (P = .044), and liver cirrhosis (P = .029) as independent risk factors for severe postoperative complications. The severe complication rates (2.7% vs 12.1%, P = .0025), median intraoperative blood loss (100 mL vs 150 mL, P = .001), and median operation time (248 minutes vs 299.5 minutes, P = .0013) were lower in the patients without all these three risk factors than those with at least one risk factor. The median length of postoperative hospital stay was shorter in patients with no risk factors than those with at least one risk factor (9 days vs. 10 days, P = .001). CONCLUSIONS: Tumor size ≥3 cm, segmentectomy, and liver cirrhosis were the risk factors for severe postoperative complications after parenchyma-sparing pure LLR for tumors in the right PS segments. Patients without these three risk factors would be appropriate candidates for safely performing parenchyma-sparing pure LLR in the right PS segments at the outset. - 動脈結紮術を施行した未破裂第一空腸動脈瘤の1例山田 淳史; 松本 逸平; 松本 正孝; 吉田 雄太; 登 千穂子; 川口 晃平; 李 東河; 亀井 敬子; 里井 俊平; 武部 敦志; 中居 卓也; 竹山 宜典日本臨床外科学会雑誌 日本臨床外科学会 82 (増刊) S863 - S863 1345-2843 2021/10

Neoadjuvant chemotherapy (NAC) is thought to be an effective treatment modality, but its prognostic impact is still unclear. MATERIALS AND METHODS: Patients with resectable SCRLM presented to eight university hospitals between 2007 and 2017 were retrospectively reviewed. Propensity score matching (PSM) was performed to adjust baseline characteristics between patients who received NAC with those who underwent up-front hepatectomy. The prognostic impact of NAC was then evaluated. RESULTS: The cohort comprised of 320 patients: 151 patients received NAC and the remaining 169 patients underwent up-front hepatectomy. After a 1:1 ratio of PSM, 102 patients per group were selected. Within the PSM cohort, 66% patients had multiple liver tumors, with 15% having five or more liver tumors. The median survival (95% confidence interval) periods for patients with and without NAC in the PSM cohort were 88.5 (68.4 - not reached) and 84.2 (52.1 - not reached) months, respectively (P = 0.51). On multivariate analysis, the postoperative events in these patients including operative complications and use of adjuvant chemotherapy after hepatectomy were prognostic factors with hazards (95% confidence interval) being 1.88 (1.18-2.98) and 0.65 (0.42-1.01), respectively. CONCLUSION: This PSM study was restricted to patients with SCRLM and relatively advanced tumor stagings. NAC did not show any significant prognostic impact. While operative complications had a significant prognostic impact, use of adjuvant chemotherapy after hepatectomy had only a marginal prognostic impact. Reconsideration of indications for NAC is needed.

Background: Although several risk factors for incisional hernia after hepatectomy have been reported, their relationship to different wound sites has not been investigated. Therefore, this study aimed to examine the risk factors for incisional hernia according to various wound sites after hepatectomy. Methods: Patients from the Osaka Liver Surgery Study Group who underwent open hepatectomy using combinations of vertical and horizontal incisions (J-shaped incision, reversed L-shaped incision, reversed T-shaped incision, Mercedes incision) between January 2012 and December 2015 were included. Incisional hernia was defined as a hernia occurring within 3 y after surgery. Abdominal incisional hernia was classified into midline incisional hernia and transverse incisional hernia. The risk factors for each posthepatectomy incisional hernia type were identified. Results: A total of 1057 patients met the inclusion criteria. The overall posthepatectomy incisional hernia incidence rate was 5.9% (62 patients). In the multivariate analysis, the presence of diabetes mellitus and albumin levels <3.5 g/dL were identified as independent risk factors. Moreover, incidence rates of midline and transverse incisional hernias were 2.4% (25 patients), and 2.3% (24 patients), respectively. In multivariate analysis, the independent risk factor for transverse incisional hernia was the occurrence of superficial or deep incisional surgical site infection, and interrupted suturing for midline incisional hernia. Conclusions: Risk factors for incisional hernia after hepatectomy depend on the wound site. To prevent incisional hernia, running suture use might be better for midline wound closure. The prevention of postoperative wound infection is important for transverse wounds, under the presumption of preoperative nutrition and normoglycemia. - 局所進行切除不能膵癌に対するConversion surgeryのタイミング〜内科と外科の連携〜 当院における局所進行切除不能膵癌に対するconversion surgeryの短期・長期成績の検討吉田 雄太; 松本 逸平; 川口 晃平; 松本 正孝; 李 東河; 村瀬 貴昭; 亀井 敬子; 里井 俊平; 武部 敦志; 中居 卓也; 鎌田 研; 山雄 健太郎; 竹中 完; 竹山 宜典膵臓 (一社)日本膵臓学会 36 (3) A146 - A146 0913-0071 2021/08

The present study evaluated the efficacy of the "slow firing method" using a reinforced triple-row stapler (Covidien, Tokyo, Japan) during LDP. METHODS: This retrospective single-center study included 73 consecutive patients who underwent LDP using the slow firing method. A black cartridge was used in all patients. The primary endpoint was the rate of clinically relevant POPF (CR-POPF) after LDP. Secondary endpoints included perioperative outcomes and factors associated with CR-POPF as well as the correlation between the transection time and thickness of the pancreas. RESULTS: Four patients (5.5%) developed CR-POPF (grade B). Overall morbidity rates, defined as grade ≥ II and ≥ III according to the Clavien-Dindo classification, were 21 and 11%, respectively. The median postoperative hospital stay was 10 days. Preoperative diabetes (13.6 vs. 0.2%, P = 0.044) and thickness of the pancreas ≥ 15 mm (13.8% vs. 0%, P = 0.006) were identified as independent risk factors for CR-POPF. The median transection time was 16 (8-29) min. CONCLUSION: The slow firing method using a reinforced triple-row stapler for pancreatic transection is simple, safe, and effective for preventing CR-POPF after LDP.

METHODS: Between January 2011 and December 2013, 384 patients who underwent hepatectomy in four university hospitals in Japan were investigated as a discovery cohort. The CRP-Albumin-Lymphocyte (CALLY index) was defined as (Albumin × Lymphocyte)/(CRP × 104). Patients with a CALLY index ≥5 (n = 200) were compared to those with an index <5 (n = 184). Next, validation was performed using 267 patients from three other university hospitals (external validation cohort). RESULTS: The number of TNM Stage III and IV patients was significantly higher in the CALLY <5 group than the ≥5 group (p = 0.003). There was a significant difference in the 5-year survival rate (CALLY ≥5: 71% vs. <5: 46%; p < 0.001). Multivariate analysis identified the CALLY index as an independent factor of overall survival. Similarly, there was a significant difference in the 5-year survival rate between the CALLY ≥5 (73%) and <5 (48%) groups (p < 0.001), and the CALLY index was identified as an independent prognostic factor in the external validation cohort. CONCLUSION: The CALLY index derived from CRP, albumin, and lymphocyte values is a promising predictive biomarker for postoperative prognosis of patients with HCC.

METHODS: This retrospective single-center study included 70 consecutive patients undergoing LDP. The primary endpoint was the rate of conversion to open surgery during LDP. The secondary endpoints were determining the reasons for conversion to open surgery, with detailed analyses of these cases and a comparison of the surgical outcome with and without conversion. RESULTS: Seven patients (10%) required conversion to open surgery during LDP. Pancreatic ductal adenocarcinoma (PDAC) was identified as a risk factor for conversion (p = 0.010). The reasons for conversion included technical difficulty (two bleeding, one severe adhesion) and pancreatic stump-related issues (two margin-positive, two stapling failures). Although the overall morbidity rate (29 vs. 11%, p = 0.48) and the rate of clinically relevant postoperative pancreatic fistula (14 vs. 5%, p = 0.82) were no different for the patients with or without open conversion, the postoperative hospital stay was significantly longer in the former (median 15 vs. 10 days, p = 0.03). CONCLUSIONS: Careful preoperative assessment is required when planning LDP for PDAC. Although conversion to open surgery does not result in failure of LDP, efforts to reduce the duration of postoperative hospital stay and the occurrence of complications are desirable to improve the outcome of LDP.

BACKGROUND: Hepatic resection (HR) is not recommended for intermediate-stage hepatocellular carcinoma (HCC) by the Barcelona Clinic Liver Cancer criteria. We examined the prognostic factors of HR for intermediate-stage HCC and developed new HR criteria for intermediate-stage HCC. METHODS: A total of 110 patients who underwent HR without any prior treatment for intermediate-stage HCC between January 2007 and December 2012 were enrolled at eight university hospitals. The outcomes and prognostic factors of HR were evaluated to develop new HR criteria. RESULTS: In terms of tumor size and number, the most significant prognostic factors were within the up-to-seven criteria. Furthermore, serum albumin level ≥35 g/L and serum alpha-fetoprotein (AFP) level. - 周術期合併症は大腸癌同時性肝転移切除後の予後に影響する上野 昌樹; 米田 浩二; 小坂 久; 野見 武男; 飯田 洋也; 田中 肖吾; 中居 卓也; 松田 健司; 廣川 文鋭; 北東 大督; 海堀 昌樹; 谷 眞至; 内山 和久; 山上 裕機; 久保 正二日本臨床外科学会雑誌 日本臨床外科学会 81 (増刊) 325 - 325 1345-2843 2020/10

They usually occur in patients with acute or chronic pancreatitis but are rarely associated with pancreatic neoplasm. We present here an extremely rare case of pancreatic neuroendocrine tumor with stenosis of the main pancreatic duct, leading to pancreatic pleural effusion. CASE PRESENTATION: A 51-year-old man complained of dyspnea. Left-sided pleural effusion was detected on the chest X-ray. Pleural puncture was performed, and the pleural fluid indicated a high amylase content (36,854 IU/L). Hence, the patient was diagnosed with pancreatic pleural effusion. Although no tumor was detected, the computed tomography (CT) scan showed a pseudocyst and dilation of the main pancreatic duct in the pancreatic tail. Magnetic resonance cholangiopancreatography showed a fistula from the pseudocyst into the left thoracic cavity. Endoscopic retrograde pancreatic drainage was attempted; however, it failed due to stenosis in the main pancreatic duct in the pancreatic body. Endoscopic ultrasound revealed a hypoechoic mass measuring 15 × 15 mm in the pancreatic body that was not enhanced in the late phase of contrast perfusion and was thus suspected to be an invasive ductal carcinoma. The patient underwent distal pancreatectomy with splenectomy and the postoperative course was uneventful. Histopathological examination confirmed a neuroendocrine tumor of the pancreas (NET G2). The main pancreatic duct was compressed by the tumor. Increased pressure on the distal pancreatic duct by the tumor might have caused formation of the pseudocyst and pleural effusion. To the best of our knowledge, this is the first case report of pancreatic pleural effusion associated with a neuroendocrine tumor. CONCLUSIONS: Differential diagnosis of a pancreatic neoplasm should be considered, especially when a patient without a history of pancreatitis presents with pleural effusion.

METHODS: The records of 151 consecutive patients undergoing surgery for CP were retrospectively reviewed. Selection of surgical procedures used had been according to the Japanese Clinical Practice Guidelines for CP 2015. Long-term (≥1 year) follow-up was performed in 100 patients (median of 37 months). RESULTS: Surgical drainage procedures were performed in 107 patients (Frey operation in 81, longitudinal pancreaticojejunostomy in 26), pancreatic resection in 37 (subtotal stomach-preserving pancreaticoduodenectomy in 11, distal pancreatectomy in 26), and other procedures in six. The rates of postoperative mortality and morbidity were 1% and 26%, respectively. The rates of complete and partial pain relief were 62% and 37%. The frequency of occurrence of severe morbidity was significantly higher after pancreatic resection than in patients receiving drainage procedures (13% vs 2%, P = .019). The rate of new-onset diabetes was also significantly higher after resection than drainage (60% vs 25%, P = .017). CONCLUSIONS: Surgical treatment for painful chronic pancreatitis can be safe and effective. An optimal procedure should guarantee pain relief and preserve a maximum of pancreatic function.

BACKGROUND: Hepatic resection often results in delirium in preoperatively self-sufficient elderly people. The association of frailty with postoperative delirium remains unclear, and preoperative risk assessment, including frailty, of postoperative delirium has not been established. METHODS: This prospective multicenter study included 295 independently living patients aged ≥ 65 years scheduled for initial hepatic resection. All patients answered the phenotypic frailty index Kihon Checklist, which is a self-reporting list of 25 questions, within a week before surgery. The risk factors for postoperative delirium were investigated. Patients who scored ≥ 4 in the Intensive Care Delirium Screening Checklist were designated as having postoperative delirium. RESULTS: Delirium developed after liver resection in 22 of 295 patients (7.5%). Total Kihon Checklist score (≥ 6 points), age (≥ 75 years), and serum albumin concentration (≤ 3.7 g/dL) were the independent risk factors for postoperative delirium. The proportion of patients with postoperative delirium was 0% in those with no applicable risk factors, 3.2% in those with one applicable risk factor, 12.0% in those with two applicable risk factors, and 40.9% in those with all three factors (p < 0.001). The area under the receiver operating characteristic curve for this risk assessment for predicting postoperative delirium was 0.842. CONCLUSION: The use of these three factors for preoperative risk assessment may be effective in predicting and preparing for delirium after hepatic resection in elderly patients. - Takeo Nomi; Fumitoshi Hirokawa; Masaki Kaibori; Masaki Ueno; Shogo Tanaka; Daisuke Hokuto; Takehiro Noda; Takuya Nakai; Hisashi Ikoma; Hiroya Iida; Koji Komeda; Morihiko Ishizaki; Shinya Hayami; Hidetoshi Eguchi; Masataka Matsumoto; Ryo Morimura; Hiromitsu Maehira; Masayuki Sho; Shoji KuboSurgical endoscopy 34 (2) 658 - 666 2020/02 [Refereed]
BACKGROUND: The frequency of liver resection in elderly patients has been increasing. However, data are limited regarding the safety of laparoscopic liver resection (LLR) compared with that of open liver resection (OLR) for hepatocellular carcinoma (HCC) in elderly patients. The present study aimed to compare short-term outcomes between LLR and OLR in elderly patients with HCC using propensity score matching. METHODS: The study included 630 patients (age, ≥ 75 years) who underwent liver resection for HCC at nine liver centres between April 2010 and December 2017. Patients were divided into LLR and OLR groups, and perioperative outcomes were compared between the groups. In addition, subgroup analysis was performed according to age (75-79 and ≥ 80 years). RESULTS: Of the 630 patients, 221 and 409 were included in the LLR and OLR groups, respectively. After propensity score matching, 155 patients were included in each group. Intraoperative blood loss and the transfusion, post-operative overall complication and major complication rates were lower in the matched LLR than the matched OLR group (P < 0.001, P = 0.004, P < 0.001 and P < 0.001, respectively). Moreover, post-operative pulmonary and cardiovascular complications were less frequent in the matched LLR group (P = 0.008 and P = 0.014, respectively). In subgroup analysis, among octogenarians, the post-operative major complication rate was lower and hospital stay was shorter in the matched LLR than the matched OLR group (P < 0.001 and P < 0.001, respectively). CONCLUSION: LLR for HCC is associated with good short-term outcomes in patients aged ≥ 75 years compared with OLR. LLR is safe and feasible in selected octogenarians with HCC. - 【慢性膵炎診療2020】治療・予後 膵石の内視鏡治療vs.外科治療 最近の知見松本 逸平; 松本 正孝; 村瀬 貴昭; 亀井 敬子; 里井 俊平; 武部 敦志; 中居 卓也; 三長 孝輔; 竹中 完; 竹山 宜典肝・胆・膵 (株)アークメディア 80 (2) 355 - 362 0389-4991 2020/02 [Refereed]

We have developed a novel stump closure technique after DP using transpancreatic mattress suture with Vicryl mesh (TMV) and reported our initial findings. The purpose of this study is to evaluate the efficacy of TMV compared to the conventional handsewn stump closure technique (CHS). METHODS: This retrospective single-center study included 165 consecutive patients who underwent open DP from January 2010 to May 2018. Of these, 71 patients underwent DP using TMV after September 2014 and 94 patients underwent DP with CHS. The surgical outcomes were compared between the two groups. RESULTS: Clinically relevant POPF rate in the TMV group was significantly lower than that in the CHS group (5.6% vs. 17.2%, P = 0.027). Morbidity rate was higher in the CHS group than that in the TMV group (16.9% vs. 27.7%, P = 0.104). In the multivariate analysis, absence of additional organ resection (OR 3.57; 95% CI 1.18-10.43; P = 0.025) and TMV (OR 0.24; 95% CI 0.07-0.73; P = 0.010) were identified as independent preventing factors for clinically relevant POPF. CONCLUSION: TMV can be an effective stump closure technique for preventing POPF after DP.

OBJECTIVE: To establish a preoperative risk assessment method for loss of independence after hepatic resection. SUMMARY BACKGROUND DATA: Hepatic resection often results in loss of independence in preoperatively self-sufficient elderly people. Elderly patients should therefore be carefully selected for surgery. METHODS: In this prospective, multicenter study, 347 independently-living patients aged ≥65 years, scheduled for hepatic resection, were divided into study (n = 232) and validation (n = 115) cohorts. We investigated the risk factors for postoperative loss of independence in the study cohort and verified our findings with the validation cohort. Loss of independence was defined as transfer to a rehabilitation facility, discharge to residence with home-based healthcare, 30-day readmission for poor functionality, and 90-day mortality (except for cancer-related deaths). RESULTS: In the study cohort, univariate and multivariate analyses indicated that frailty, age ≥ 76 years, and open surgery were independent risk factors for postoperative loss of independence. Proportions of patients with postoperative loss of independence in the study and validation cohorts were respectively 3.0% and 0% among those with no applicable risk factors, 8.1% and 12.5% among those with 1 applicable risk factor, 25.5% and 25.0% among those with 2 applicable risk factors, and 56.3% and 50.0% among those with all 3 factors applicable (P < 0.001 for both cohorts). Areas under the receiver operating characteristic curves for the study and validation groups were 0.777 and 0.783, respectively. CONCLUSIONS: Preoperative risk assessments using these 3 factors may be effective in predicting and planning for postoperative loss of independence after hepatic resection in elderly patients. - Frailな患者に対する消化器外科手術 術前フレイル判定は肝切除後の加齢に関連した合併症の予測因子になりうる 多施設前向き研究による検討田中 肖吾; 上野 昌樹; 飯田 洋也; 海堀 昌樹; 野見 武男; 廣川 文鋭; 生駒 久視; 中居 卓也; 江口 英利; 久保 正二日本消化器外科学会総会 (一社)日本消化器外科学会 74回 WS18 - 8 2019/07

METHODS: This retrospective comparative study included 67 consecutive patients who underwent LDP (n = 32) and ODP (n = 35) for benign or low-grade malignant lesions of the pancreas from January 2012 to March 2017. Thirty-five patients who were eligible for LDP in the ODP group were carefully selected. The clinical outcomes were compared in an intention-to-treat analysis. RESULTS: LDP was associated with significantly less operative blood loss (182 ± 232 vs. 505 ± 376 ml, P < 0.001) but a longer operation time (327 ± 89 vs. 173 ± 48 min, P < 0.001), than ODP. There were no significant differences between the 2 groups in the overall morbidity rates defined by Clavien-Dindo classification ≥ grade II (13% vs. 11%), clinically relevant postoperative pancreatic fistula rates (6% vs. 9%), and lengths of postoperative hospital stay (11 vs. 11 days). CONCLUSION: The study showed that LDP was safe and feasible. LDP should be considered as the first-line treatment for benign and low-grade malignant lesions in the left side of the pancreas.

This duct poses the risk for intraoperative bile duct injury resulting in clinically relevant bile leakage. PRESENTATION OF CASE: Aberrant subvesical bile duct was detected by preoperative magnetic resonance cholangiopancreatography in a 52-year old woman with gallbladder polypoid tumor harboring the risk to be gallbladder cancer. During open cholecystectomy with full thickness dissection, the aberrant duct was identified by intraoperative fluorescent cholangiography (IFC), and dissected safely. DISCUSSION: Aberrant subvesical bile ducts are mostly found unexpectedly as intra and/or postoperative bile leakage, and remain an important cause of bile duct injuries after laparoscopic cholecystectomy. IFC, which offers real-time imaging of biliary anatomy, has a potential to overcome these problems. CONCLUSION: We performed cholecystectomy by using IFC to identify the aberrant subvesical bile duct. To the best of our knowledge, this is the first report showing the fluorescence image of an aberrant subvesical bile duct in a state of nature.

The aim of the present study was to retrospectively identify prognostic factors for long-term cumulative survival following liver resection in patients with primarily unresectable colorectal cancer who had previously received conversion therapy. A multicentre study was designed to ascertain the appropriate indication for conversion therapy. The study included 34 patients who underwent conversion therapy at 5 university hospitals. Patients' background, operative factors, recurrence rate and survival rate were evaluated, and factors influencing therapy outcomes were identified. The median duration of preoperative chemotherapy was 3 months and the response rate was 39.8%. Upon resection, the median tumour size was 47 mm and the median number of tumours was 4. The recurrence-free and cumulative survival rates 5 years after liver resection were 13.7 and 39.3%, respectively. Postoperative complications developed in 12 patients. A response rate >40% was indicated with regards to the assessed prognostic factors for long-term cumulative survival following liver resection and an absence of postoperative complications was noted. It was revealed that conversion therapy should be considered prior to liver resection, particularly for patients with response rates exceeding 40%. Absence of postoperative complications is also an independent predictor of long-term cumulative survival after liver resection. In light of these findings, it was consisted that an optimal response rate >40% could be used as an indicator for surgical resection in conversion therapy. In addition, meticulous intra- and postoperative managements are important for decreasing postoperative complications and improving long-term cumulative survival. - 膵全摘術の治療成績松本 逸平; 吉田 雄太; 川口 晃平; 松本 正孝; 村瀬 貴昭; 岩崎 寿光; 亀井 敬子; 里井 俊平; 武部 敦志; 中居 卓也; 竹山 宜典日本消化器外科学会雑誌 (一社)日本消化器外科学会 51 (Suppl.2) 376 - 376 0386-9768 2018/11

All rights reserved. Background and Aim: Differential diagnosis of localized gallbladder lesions is challenging. The aim of the present study was to evaluate the utility of contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) for diagnosis of localized gallbladder lesions. Methods: One hundred and twenty-five patients with localized gallbladder lesions were evaluated by CH-EUS between March 2007 and February 2014. This was a single-center retrospective study. Utilities of fundamental B-mode EUS (FB-EUS) and CH-EUS in the differentiation of gallbladder lesions and sludge plug were initially compared. Thereafter, these two examinations were compared with respect to their accuracy in the diagnosis of malignant lesions. Five reviewers blinded to the clinicopathological results evaluated microcirculation patterns in the vascular and perfusion images. Results: In the differentiation between gallbladder lesions and sludge plug, FB-EUS had a sensitivity, specificity, and accuracy of 82%, 100%, and 95%, respectively, whereas CH-EUS had a sensitivity, specificity, and accuracy of 100%, 99%, and 99%, respectively. FB-EUS-based diagnosis of carcinomas based on tumor size and/or shape had a sensitivity, specificity, and accuracy of 61-87%, 71-88%, and 74-86%, respectively. Additional information regarding irregular vessel patterns in the vascular image and/or heterogeneous enhancement in the perfusion image on CH-EUS increased the sensitivity, specificity, and accuracy for the diagnosis of carcinomas to 90%, 98 %, and 96%, respectively. There was a significant difference between FB-EUS and CH-EUS in terms of carcinoma diagnosis. Conclusion: CH-EUS was useful for the evaluation of localized gallbladder lesions.

BACKGROUND: Age-related events, such as cardiopulmonary complications, delirium, transfer to a rehabilitation facility, and dependency are a major problem after hepatic resection in the elderly. This prospective multicenter study aimed to preoperatively evaluate frailty in the elderly according to a phenotypic frail index, named the "Kihon Checklist (KCL)," to predict "age-related events" after hepatic resection. METHODS: Between May 2016 and September 2017, 217 independently living patients who consented among all patients aged ≥65 years who planned to undergo hepatic resection were included in the study. Preoperative frailty was defined as a total KCL score ≥8. We analyzed clinical characteristics and outcomes, including age-related events (major respiratory and cardiac complications, delirium medication needed, transfer to rehabilitation facility, and dependency) between patients with and without frailty. RESULTS: Of the 217 patients, 63 and 154 were classified into the frail and non-frail groups, respectively. The incidences of age-related events (31.7% vs. 7.8%, P < 0.001) were higher in the frail group. Multivariate analysis indicated that frailty (P < 0.001, hazard ratio 5.16) and resection of ≥2 sectors (P = 0.014, hazard ratio 2.98) were independent risk factors for age-related events. CONCLUSIONS: Frailty evaluated by KCL in the elderly can predict postoperative age-related events after hepatic resection. - 大塚 康生; 鎌田 研; 竹中 完; 石川 嶺; 岡本 彩那; 中井 敦史; 大本 俊介; 三長 孝輔; 山雄 健太郎; 筑後 孝章; 兵頭 朋子; 中居 卓也; 竹山 宜典; 工藤 正俊胆道 日本胆道学会 32 (3) 567 - 567 0914-0077 2018/08

PURPOSE: The influence of allogenic blood transfusion on the postoperative outcomes of hepatocellular carcinoma (HCC) surgery remains controversial. This study aims to clarify the clinical impacts of perioperative allogenic blood transfusion on liver resection outcome in HCC patients. METHODS: We analyzed data collected over 5 years for 642 patients who underwent hepatectomy for HCC at one of the five university hospitals. We investigated the impact of allogenic blood transfusion on postoperative outcome after surgery in all patients and in 74 matched pairs, using a propensity score. RESULTS: Of the 642 patients, 198 (30.8%) received perioperative allogenic blood transfusion (AT group) and 444 (69.2%) did not (non-AT group). Overall survival was lower in the AT group than in the non-AT group in univariate (P < 0.001) and multivariate analyses (risk ratio 1.521, P = 0.011). After matching the different distributions using propensity scores, perioperative blood transfusion was found to be a poor prognostic factor for HCC patients. CONCLUSIONS: In this multi-center study, perioperative blood transfusion was an independent factor for poor prognosis after curative surgery for primary HCC in the patient group and in pairs matched by propensity scores. - Ken Kamata; Mamoru Takenaka; Masayuki Kitano; Shunsuke Omoto; Takeshi Miyata; Kosuke Minaga; Kentaro Yamao; Hajime Imai; Tosiharu Sakurai; Naoshi Nishida; Hiroshi Kashida; Takaaki Chikugo; Yasutaka Chiba; Takuya Nakai; Yoshifumi Takeyama; Andrea Lisotti; Pietro Fusaroli; Masatoshi KudoDigestive Endoscopy WILEY 30 (1) 98 - 106 0915-5635 2018/01© 2017 Japan Gastroenterological Endoscopy Society Background and Aim: Differential diagnosis of localized gallbladder lesions is challenging.

We present a case ofa 67-year-old woman with Stage IV pancreatic head cancer with invasion to the superior mesenteric vein and artery, and distant lymph node metastases. The patient received S-1 mono-chemotherapy. After 2 courses of chemotherapy, the tumor marker was decreased to the normal levels, and the tumor size was dramatically reduced with undetectable lymph node metastases on CT. As the disease status was maintained following chemotherapy, the patient underwent subtotal stomach preserving pancreaticoduodenectomy, 8 months after initiation of the chemotherapy. Histopathologically, no cancer cells were found in the main tumor and dissected lymph nodes. Final diagnosis was made with pathological complete response. The patient was alive without recurrence for 10 months after surgery. - 大腸癌肝転移おけるNAC後肝切除症例のTNIを用いた臨床病理学的予後解析による術後化学療法の指針中居 卓也; 川口 晃平; 松本 正孝; 村瀬 貴昭; 亀井 敬子; 里井 俊平; 松本 逸平; 竹山 宜典日本消化器外科学会雑誌 (一社)日本消化器外科学会 50 (Suppl.2) 272 - 272 0386-9768 2017/10

BACKGROUND AND OBJECTIVES: We determined the rates of initial lymph node metastasis following curative resection of mass-forming type-intrahepatic cholangiocarcinoma (ICC) in patients with and without hepatitis virus infection. METHODS: We enrolled 87 patients between January 2000 and December 2013 with ICC without preoperative lymph node metastasis and without lymph node dissection. Patients included 32 who were seropositive for hepatitis B or C virus (virus group) and 55 who had no evidence of hepatitis virus infection (nonvirus group). Postsurgical outcomes and initial recurrence of the groups were compared, and we identified the risk factors for lymph node metastasis as initial recurrence. RESULTS: Platelet counts and prothrombin activities were significantly lower in the virus group compared with those of the nonvirus group. The number of patients with chronic hepatitis or liver cirrhosis was significantly higher in the virus group compared with the nonvirus group as well as their respective rates of recurrence-free survival. One patient (3%) in the virus group and 14 patients (25%) in the nonvirus group had lymph node metastasis as initial recurrence (p = 0.007). Multivariate analysis revealed that the absence of hepatitis virus infection as an independent risk factor (p = 0.047). CONCLUSION: Hepatitis virus-associated mass-forming-type ICC confers a low risk of lymph node metastasis as initial postoperative recurrence. - 肥満若年男性から発生した肝細胞腺腫が悪性転化した1例幕谷 悠介; 川口 晃平; 松本 正孝; 村瀬 貴昭; 亀井 敬子; 里井 俊平; 松本 逸平; 中居 卓也; 竹山 宜典日本外科学会定期学術集会抄録集 (一社)日本外科学会 117回 RS - 4 2017/04 [Refereed]

BACKGROUND: While spontaneously ruptured hepatocellular carcinoma (HCC) has a poor prognosis, the true impact of a rupture on survival after hepatic resection is unclear. METHODS: Fifty-eight patients with ruptured HCC and 1922 with non-ruptured HCC underwent hepatic resection between 2000 and 2013. To correct the difference in the clinicopathological factors between the two groups, propensity score matching (PSM) was used at a 1:1 ratio, resulting in a comparison of 42 patients/group. We investigated outcomes in all patients with ruptured HCC and compared outcomes between the two matched groups. RESULTS: Of the 58 patients with ruptured HCC, 7 patients (13 %) died postoperatively. Overall survival (OS) rate at 5 years after hepatic resection was 37 %. Emergency hepatic resection was an independent risk factor for in-hospital death and Child-Pugh class B for unfavorable OS in multivariate analysis. Clinicopathological variables were well-balanced between the two groups after PSM. No significant differences were noted in incidence of in-hospital death (ruptured HCC 12 % vs non-ruptured HCC 2 %, p = 0.202) or OS rate (5/10-year; 42 %/38 % vs 67 %/30 %, p = 0.115). CONCLUSION: Emergency hepatic resection should be avoided for ruptured HCC in Child-Pugh class B patients. Rupture itself was not a risk for unfavorable surgical outcomes. - Masaki Kaibori; Hiroyuki Nitta; Michihiro Hayashi; Shigekazu Takemura; Hiroaki Nagano; Kosuke Matsui; Hisashi Ikoma; Takuya Nakai; Masafumi Yasunaga; Masahiro Kido; Takeshi Aoki; Toshiki Rikiyama; Keiji Sano; Atsushi Kudo; Satoshi Katagiri; Yuichiro Otsuka; Tamotsu Kuroki; Takeo Nomi; Koichi Yano; Itaru Endo; Masaki Ueno; Akishige Kanazawa; Hiroaki Terajima; Saiho Ko; Goro Honda; Yasuji Seyama; Hiroki Sunagawa; Tsukasa AibaraJOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES SPRINGER JAPAN KK 23 (11) 697 - 702 1868-6974 2016/11 [Refereed]
BackgroundAmong young residents, there seems to be a decreasing desire to become surgeons, resulting in a decrease in the number of surgeons. There is concern regarding a shortage of hepatobiliary pancreatic (HBP) surgery residents in Japan. A questionnaire survey was designed to assess the work motivations of Japanese gastrointestinal (GI) and HBP surgeons. MethodsQuestionnaires assessing seven domains related to motivation (aptitude, satisfaction/dissatisfaction, knowledge/skill, evaluation/approval, self-management, community/expectation from other parties, and emotion) were sent to GI and HBP surgeons throughout Japan. Differences between HBP and GI surgeons were analyzed. ResultsResponses were received from 27 institutions in Japan between May and August 2014. Mid-career and senior HBP surgeons (11-20years after graduation) working in university hospitals were significantly less satisfied with their work than GI surgeons (P=0.036). Evaluation/approval factors were significantly lower in senior HBP surgeons than in GI surgeons 16-20years after graduation (P=0.048). ConclusionsThe future satisfaction of young residents seeking to become HBP surgeons should be enhanced, providing an appealing workplace for young residents and preventing discontinuation by mid-career and senior surgeons. - Ippei Matsumoto; Keiko Kamei; Shumpei Satoi; Takuya Nakai; Yoshifumi TakeyamaINTERNATIONAL SURGERY INT COLLEGE OF SURGEONS 101 (11-12) 550 - 553 0020-8868 2016/11 [Refereed]
Portal annular pancreas (PAP) is an asymptomatic congenital pancreatic anomaly in which the uncinate process of the pancreas extends and fuses to the dorsal surface of the body of the pancreas by surrounding the portal vein and or the superior mesenteric vein. During pancreaticoduonectomy (PD), the presence of PAP significantly increased risk for postoperative pancreatic fistula (POPF) because specific management of 2 pancreatic resection planes with 1 or 2 pancreatic ducts is required for pancreatico-intestinal reconstruction. To reduce the risk of POPF, a shift of the resection plain to the left for 1 anastomosis is recommended. We report a case of PAP that was successfully performed PD with pancreaticogastrostomy (PG). PG was conducted with invagination of the 2 resected pancreatic planes together into the stomach to minimize resected volume of the pancreas. A 78-year-old male patient with PAP underwent PD due to a duodenal adenocarcinoma. Intraoperatively, the uncinate process extended extensively behind the portal vein and fused with the dorsal surface of the pancreatic body above the splenic vein. For pancreatico-intestinal reconstruction, PG was performed with invagination of the 2 resected pancreatic planes together into the stomach. The postoperative course was uneventful, and he was discharged on postoperative day 12. Endocrine and exocrine function of the pancreas were maintained well at 10 months after surgery. PG is one of the useful choices for patients with PAP to prevent POPF while maintaining the pancreatic endocrine and exocrine function after PD. - 膵胆管合流異常症に合併した胆管内乳頭状腫瘍の1例幕谷 悠介; 松本 逸平; 松本 正孝; 村瀬 貴昭; 亀井 敬子; 里井 俊平; 中居 卓也; 竹山 宜典日本臨床外科学会雑誌 日本臨床外科学会 77 (増刊) 680 - 680 1345-2843 2016/10 [Refereed]

Background. Local recurrence is a specific problem after radiofrequency ablation of small hepatocellular carcinoma, and additional treatment is an important issue. We aimed to investigate the outcome of salvage hepatectomy in patients who develop local, recurrent hepatocellular carcinoma after treatment with radiofrequency ablation. Methods. From 2001-2013, we reviewed 58 patients from 6 university hospitals with local, recurrent hepatocellular carcinoma who underwent salvage hepatectomy after their initial radiofrequency ablation treatment. Pathologic characteristics and prognostic factors influencing overall survival were analyzed. Results. Noncurative resection, des-gamma carboxy prothrombin levels >40 mAU/mL, and multiple preceding treatments before salvage hepatectomy were negative prognostic factors for overall survival. The 5-year survivals for the prognostic factors were 0 %, 24 %, and 30%, respectively, after salvage hepatectomy, and 0%, 54%, and 54% after initial radiofrequency ablation treatment, respectively. As for the pathologic finding of local, recurrent hepatocellular carcinoma after radiofrequency ablation, vascular invasion was observed frequently in patients with increases in des-gamma carboxy prothrombin levels and with multiple preceding treatments before salvage hepatectomy with a frequency of 59% and 53 %, respectively (P < .01 and .05). Conclusion. Noncurative resection, increases in serum des-gamma carboxy prothrombin, and multiple preceding treatments were prognostic factors for subsequent salvage hepatectomy; nevertheless, survival outcomes were still acceptable when a curative salvage hepatectomy was performed. Increases in serum des-gamma carboxy prothrombin and multiple preceding treatments were positive predictors for pathologic vascular invasion. These factors should be taken into consideration when selecting treatment modalities for locally recurrent hepatocellular carcinoma following radiofrequency ablation. Repetition of unsuccessful, loco-regional treatment would appear to decrease the potential survival. - Ippei Matsumoto; Yoshifumi Takeyama; Keiko Kamei; Shumpei Satoi; Yasuyuki Nakata; Hajime Ishikawa; Takaaki Murase; Masataka Matsumoto; Takuya NakaiJOURNAL OF THE AMERICAN COLLEGE OF SURGEONS ELSEVIER SCIENCE INC 223 (2) E1 - E5 1072-7515 2016/08 [Refereed]

Hepatectomy is the most effective treatment for patients with colorectal liver metastasis (CRLM). However, the procedure is also associated with a high risk of recurrence, and adjuvant chemotherapy for postoperative recurrence remains controversial. We investigated the efficacy of adjuvant chemotherapy for CRLM with the clinical risk score (CRS) proposed by Fong et al. Patients with CRLM who were treated, without preoperative chemotherapy, between 1992 and 2012 were classified as having low CRS (score of 0-1), intermediate CRS (2-3), or high CRS (4-5). The efficacy of adjuvant chemotherapy was retrospectively analyzed for each CRS subgroup. Of the 161 patients who underwent hepatectomy, 100 received adjuvant chemotherapy (group A) and 61 did not (group N). For intermediate CRS, 5-year disease free survival (DFS) was significant different between the groups (group A: n = 61; 33.9 % vs. group N: n = 39; 23.2 %, P = 0.008) and 5-year overall survival (OS) of group A was higher than group N (53.5 vs. 36.5 %, P = 0.048), respectively. For both low CRS and high CRS, 5-year DFS and OS were similar between the groups. Multivariate analysis of DFS identified prognostic factors as major resection for low CRS (P = 0.02) and adjuvant chemotherapy for intermediate CRS (P = 0.015). Similarly, multivariate analysis of OS identified major resection for low CRS (P = 0.05) and adjuvant chemotherapy for intermediate CRS (P = 0.05). High CRS was not identified prognostic factor. Adjuvant chemotherapy for CRLM was effective in intermediate CRS patients. In low CRS patients, adjuvant chemotherapy may not be necessary, but adequate surgical resection is important. - Akihiro Kogita; Yasumasa Yoshioka; Kazuko Sakai; Yosuke Togashi; Shunsuke Sogabe; Takuya Nakai; Kiyotaka Okuno; Kazuto NishioBIOCHEMICAL AND BIOPHYSICAL RESEARCH COMMUNICATIONS ACADEMIC PRESS INC ELSEVIER SCIENCE 458 (1) 52 - 56 0006-291X 2015/02 [Refereed]
Intra- and inter-tumor heterogeneity may hinder personalized molecular-target treatment that depends on the somatic mutation profiles. We performed mutation profiling of formalin-fixed paraffin embedded tumors of multi-regional colon cancer and characterized the consequences of intra- and inter-tumor heterogeneity and metastasis using targeted re-sequencing. We performed targeted re-sequencing on multiple spatially separated samples obtained from multi-regional primary colon carcinoma and associated metastatic sites in two patients using nextgeneration sequencing. In Patient 1 with four primary tumors (P1-1, P1-2, P1-3, and P1-4) and one liver metastasis (H1), mutually exclusive pattern of mutations was observed in four primary tumors. Mutations in primary tumors were identified in three regions; KARS (G13D) and APC (R876*) in P1-2, TP53 (A161S) in P1-3, and KRAS (G12D), PIK3CA (Q546R), and ERBB4 (T272A) in P1-4. Similar combinatorial mutations were observed between P1-4 and H1. The ERBB4 (T272A) mutation observed in P1-4, however, disappeared in H1. In Patient 2 with two primary tumors (P2-1 and P2-2) and one liver metastasis (H2), mutually exclusive pattern of mutations were observed in two primary tumors. We identified mutations; KRAS (G12V), SMAD4 (N129K, R445*, and G508D), TP53 (R175H), and FGFR3 (R805W) in P2-1, and NRAS (Q61K) and FBXW7 (R425C) in P2-2. Similar combinatorial mutations were observed between P2-1 and H2. The SMAD4 (N129K and G508D) mutations observed in P2-1, however, were nor detected in H2. These results suggested that different clones existed in primary tumors and metastatic tumor in Patient 1 and 2 likely originated from P1-4 and P2-1, respectively. In conclusion, we detected the muti-clonalities between intra- and inter-tumors based on mutational profiling in multi-regional colon cancer using next-generation sequencing. Primary region from which metastasis originated could be speculated by mutation profile. Characterization of inter- and inter-tumor heterogeneity can lead to underestimation of the tumor genomics landscape and treatment strategy of personal medicine.

Background Postoperative bile leakage can be a serious complication after hepatic resection. Few studies have analyzed patients according to the time of onset of bile leakage. We analyzed differences between patients with early- and late-onset bile leakage after hepatic resection and assessed clinical characteristics and outcomes in patients with late-onset leakage. Methods Between 2008 and 2010, 1,009 patients underwent hepatic resection at 4 participating university hospitals and 2 community hospitals. Fifty-two patients (5.1%) with postoperative bile leakage were divided into an early-onset group (< 2 weeks after surgery, n = 34) and a late-onset group (≥2 weeks after surgery, n = 18). Patient characteristics and outcomes were collected prospectively and analyzed retrospectively. Results The proportion of patients who underwent intra-abdominal placement of a drainage catheter was significantly less in the late-onset group than the early-onset group. All 18 patients in the late-onset group developed intra-abdominal infection, and 2 died of sepsis. The proportion of patients who underwent invasive treatment (abdominal paracentesis, endoscopic biliary drainage, or second hepatic resection) was significantly greater in the late-onset group than in the early-onset group. The time to resolution of bile leakage was significantly greater in the late-onset group than the early-onset group. Conclusion Patients should be monitored carefully for bile leakage for several weeks after hepatic resection, because late-onset bile leakage can cause serious complications. Intra-abdominal infection should also be treated as soon as possible, because it may induce refractory bile leakage with serious complications. - Fumitoshi Hirokawa; Shoji Kubo; Hiroaki Nagano; Takuya Nakai; Masaki Kaibori; Michihiro Hayashi; Shigekazu Takemura; Hiroshi Wada; Yasuyuki Nakata; Kosuke Matsui; Morihiko Ishizaki; Kazuhisa UchiyamaSURGERY MOSBY-ELSEVIER 157 (1) 27 - 36 0039-6060 2015/01 [Refereed]
Background. The benefits of anatomic resection in patients with small (<5 cm), solitary hepatocellular carcinomas remain unclear. Outcomes were therefore evaluated in patients who underwent anatomic resection or nonanatomic resection of small solitary hepatocellular carcinomas. Methods. Factors affecting overall survival and disease-free survival were investigated in 330 patients who underwent curative hepatectomy for solitary (<= 5 cm) hepatocellular carcinomas without macroscopic vascular invasion. In addition, a propensity score matching model with 330 patients was constructed to overcome bias, with subgroups analyzed by tumor diameter (<3 cm and 3-5 cm). Results. ICG-R15 >= 25% was confirmed as being independently associated with poorer overall survival and disease-free survival. One-to-one matching of preoperative characteristics yielded 72 pairs of patients receiving anatomic resection and nonanatomic resection, with long-term outcomes, including overall survival and disease-free survival, being similar in these 2 groups. Subgroup analysis showed that, in patients with tumors <3 cm in diameter, short-term outcomes were better in the nonanatomic resection group than in the anatomic resection group, including significantly reduced operation time (P = 02), blood loss (P = .01), blood transfusion (P < .01), complications (particularly bile leakage and abdominal abscess) (P = .04), and postoperative hospital stay (P < .01). Conclusion. Anatomic resection was not superior to nonanatomic resection in survival outcomes in patients with solitary small hepatocellular carcinomas without macroscopic vascular invasion. Rather, postoperative short-term outcomes were more favorable with nonanatomic resection. - Masaki Kaibori; Shoji Kubo; Hiroaki Nagano; Michihiro Hayashi; Takuya Nakai; Ishizaki Morihiko; Kosuke Matsui; Takahiro Uenishi; Shigekazu Takemura; Hiroshi Wada; Marubashi Shigeru; Koji Komeda; Fumitoshi Hirokawa; Yasuyuki Nakata; Kazuhisa Uchiyama; Masanori KwonHEPATO-GASTROENTEROLOGY H G E UPDATE MEDICAL PUBLISHING S A 61 (135) 2028 - 2034 0172-6390 2014/10 [Refereed]
Aims: We performed a retrospective analysis to evaluate the short and long-term impact of simultaneous prophylactic cholecystectomy with hepatectomy in these patients. Methods: We identified 642 patients who Underwent curative hepatocellular carcinoma resecion between 2001 and 2005 at five university hospitals. One hundred and twenty-five hepatocellular carcinoma patients who received left lateral sectionectomy or partial resection in the left lateral and Spiegel lobes were identified and followed. They were divided into two groups, 74 with and 51 without simultaneous cholecysItectomy. None of these patients had gallbladder stones or polyps at preoperative diagnosis. Results: Although not statistically significant, the operating time was longer and blood loss was greater in the cholecystectomy group. Patients in the cholecystectomy group had a significantly higher postoperative morbidity rate. Surgical; complications according to the Clavien classification; differed significantly between the two groups. Variables. significantly associated with complications in the unit variate and multivariate analyses were simultaneous cholecystectomy and operative blood loss >=. 1000 ml. Conclusion: Simultaneous cholecystectomy of the as, ymptomatic gallbladder with curative resection of he patocellular carcinoma in the left lateral section or Spielgel lobe resulted in higher postoperative complications Consequently, the gallbladder should be preserved except in cases of gallbladder stones or polyps. - Koji Komeda; Michihiro Hayashi; Shoji Kubo; Hiroaki Nagano; Takuya Nakai; Masaki Kaibori; Hiroshi Wada; Shigekazu Takemura; Masahiko Kinoshita; Chikato Koga; Masataka Matsumoto; Tatsuma Sakaguchi; Yoshihiro Inoue; Fumitoshi Hirokawa; A-Hon Kwon; Kazuhisa UchiyamaWorld journal of surgery 38 (10) 2692 - 7 2014/10BACKGROUND: Although several studies have reported the outcomes of surgery for the treatment of liver metastases of gastric cancer (GLM), indications for liver resection for gastric metastases remain controversial. This study was designed to identify prognostic determinants that identify operable hepatic metastases from gastric cancer and to evaluate the actual targets of surgical therapy. METHODS: Retrospective analysis was performed on outcomes for 24 consecutive patients at five institutions who underwent gastrectomy for gastric cancer followed by curative hepatectomy for GLM between 2000 and June 2012. RESULTS: Overall 5-year survival and median survival were 40.1 % and 22.3 months, respectively. Uni- and multivariate analyses showed that liver metastatic tumour size less than 5 cm was the most important predictor of overall survival (OS, p = 0.03). Four patients survived >5 years. Repeat hepatectomy was performed in three patients. Two of these patients have remained disease-free since the repeat hepatectomy. CONCLUSIONS: GLM patients with metastatic tumour diameter less than 5 cm maximum are the best candidates for hepatectomy. Hepatic resection should be considered as an option for gastric cancer patients with liver metastases.

Objective: To clarify the progression pattern of abnormal DNA methylation during the development of hepatocellular carcinoma (HCC) using a comprehensive methylation assay. Methods: We used an Infinium HumanMethylation450 BeadChip array that can analyze >485,000 CpG sites distributed throughout the genome for a comprehensive methylation study of 117 liver tissues consisting of 59 HCC and 58 noncancerous livers. Altered DNA nnethylation patterns during tumor progression were also analyzed. Results: We identified 38,330 CpG sites with significant differences in methylation levels between HCCs and noncancerous livers (DM-CpGs) using strict criteria. Of the DM-CpGs, 92% were hypomethylated and only 3,051 CpGs (8%) were hypermethylated in HCC. The DM-CpGs were more prevalent within intergenic regions with isolated CpGs. In contrast, DM-CpGs that were hypermethylated in HCC were predominantly located within promoter regions and CpG islands (p < 0.0001). The association between methylation profiles of DM-CpGs and tumor size was statistically significant, especially in hepatitis C virus (HCV)-positive cases (p = 0.0001). Conclusions: We clarified the unique characteristics of DM-CpGs in human HCCs. The stepwise progression of alterations in DNA methylation was a common feature of HCV-related hepatocarcinogenesis.

Background: Hepatic arterial infusion (HAI) or systemic chemotherapy has been used to treat unresectable colorectal liver metastases. The prognosis of the disease in recent years has been improved because chemotherapy is performed before hepatectomy to reduce tumor size (conversion therapy). The purpose of this study was to investigate the safety and efficacy of conversion therapy following HAI immunochemotherapy. Methods: Hepatic arterial infusion of 5-fluorouracil (5-FU)/polyethylene glycol (PEG)-IFNα-2a was performed in 21 patients. The primary endpoint was the safety of HAI and hepatectomy. The secondary endpoints were response rate, rate of conversion to hepatectomy, survival rate, and prognostic factors. Results: With regard to side effects, drugs were discontinued temporarily in one patient because of a decrease in white blood cell count however, other patients continued chemotherapy. The response rate with HAI was 61.9 %, and the conversion rate was 38.1 %. Hepatectomy was completed successfully without mortality. Median progression-free survival (PFS) was 11.5 months (with and without conversion, 16.7 and 4.8 months, respectively p = 0.021). Median overall survival was 34.6 months (with and without conversion, 48.4 and 26.6 months, respectively p = 0.003). Prognosis was poor when the number of metastatic tumors was ≥10 [PFS: hazard ratio (HR) 32.21, p = 0.003 overall survival (OS): HR 9.13, p = 0.07], but prognosis improved after hepatectomy (OS: HR 0.08, p = 0.09). Conclusions: Hepatic arterial infusion immunochemotherapy with 5-FU/PEG-IFNα-2a was performed safely without major side effects. Prognosis is expected to improve after successful conversion to hepatectomy. © 2013 Société Internationale de Chirurgie. - 大本 俊介; 北野 雅之; 工藤 正俊; 中居 卓也; 竹山 宜典胆道 日本胆道学会 27 (3) 600 - 600 0914-0077 2013/08

Background The present study aimed to clarify the clinicopathologic features of long-term disease-fee survival after resection of hepatocellular carcinoma (HCC). Methods This retrospective study identified 940 patients who underwent curative resection of HCC between 1991 and 2000 at five university hospitals. Seventy-four patients with 10 years of recurrence-free survival were identified and followed up. They were divided into two groups, 60 recurrence-free and 14 with recurrence after a 10-year recurrence-free period. Results Overall survival rates of recurrence and non-recurrence groups were 68 and 91 % at 16 years, and 34 and 91 % at 20 years (p = 0.02), respectively. There were five (36 %), and two deaths (3 %), respectively, after 10 recurrence-free years. A second resection for recurrence was performed in four patients (29 %), and mean survival was 15.3 years after the first hepatectomy. Although three patients in the non-recurrence group (5 %) developed esophageal and/or gastric varices, seven patients in the recurrence group (50 %) developed varices during 10 years (p < 0.0001). In multivariate analysis, preoperative and 10-year platelet count was identified as a favorable independent factor for maintained recurrence-free survival after a 10-year recurrence-free period following curative hepatic resection of HCC. Conclusions Recurrence of HCC may occur even after a 10-year recurrence-free period. Long-term follow-up after resection of HCC is important, and should be life-long. Patients with higher preoperative and 10-year platelet counts are more likely to have long-term survival after resection. A low platelet count, related to the degree of liver fibrosis, is a risk factor for recurrence and survival of HCC after curative resection. - Keiko Kamei; Takeo Yasuda; Shumpei Satoi; Hajime Ishikawa; Hiroki Sakamoto; Masayuki Kitano; Takaaki Chikugo; Takuya Nakai; Yoshifumi TakeyamaClinical journal of gastroenterology 6 (2) 156 - 9 2013/04Cystic lesions of the pancreas are sometimes difficult to diagnose. We report a case of a gastric duplication cyst (GDC) of the pancreas in an adult. A 45-year-old woman was admitted to our department for the investigation of anemia. Abdominal ultrasonography revealed a large cystic lesion, measuring about 40 × 70 mm with calcification in the tail of the pancreas. Contrast-enhanced computed tomography of the abdomen revealed a non-enhanced cystic lesion with non-enhanced wall. Endoscopic retrograde pancreatography revealed a mild extended main pancreatic duct and an aberrant pancreatic duct, but there was no communication with the cyst. We could not deny the malignancy, so distal pancreatectomy was performed. The pathological examination revealed that the inner wall of the cyst consisted of columnar epithelium and smooth muscle layer. Immunohistochemical analysis revealed the columnar epithelium to be immunopositive for cytokeratin 7 (CK7) and immunonegative for cytokeratin 20 (CK20) and the glands to be immunonegative for CK 7 and immunopositive for CK 20. Therefore, a diagnosis of GDC of the pancreas was made. On imaging, a GDC usually mimics a pancreatic pseudocyst or a cystic neoplasm of the pancreas. Therefore, even though it is rare, a GDC should be considered in the differential diagnosis of cystic tumors of the pancreas.

A 69-year-old woman with a history of hyperthyroidism was diagnosed to have a tumor of the extrahepatic bile duct. Laparotomy, for presumed cholangiocarcinoma, revealed a 2.5-cm-long, firm mass of the hilar-upper bile duct. The extrahepatic bile duct resection and lymphadenectomy was performed. Her postoperative course was uneventful and has been asymptomatic without recurrent tumor during 2 years of follow-up. Primary carcinoid tumors of the extrahepatic bile duct are very rare. Herein we report this rare case with a review of the literature © Springer 2013.

He was pointed out to have alcoholic chronic pancreatitis. Laboratory data showed inflammation and slightly elevated serum direct bilirubin and amylase. An abdominal computed tomography demonstrated huge fluid collection, multiple pancreatic pseudocysts and pancreatic calcification. The fluid showed a high level of amylase at 4,490 IU/l. Under the diagnosis of pancreatic ascites, endoscopic pancreatic stent insertion was attempted but was unsuccessful, so surgical treatment (Frey procedure and cystojejunostomy) was performed. During the operation, a huge amount of fluid containing bile acid (amylase at 1,474 IU/l and bilirubin at 13.5 mg/dl) was found to exist in the extraperitoneal space (over the peritoneum), but no ascites was found. His postoperative course was uneventful and he shows no recurrence of the fluid. Pancreatic ascites is thought to result from the disruption of the main pancreatic duct, the rupture of a pancreatic pseudocyst, or possibly leakage from an unknown site. In our extremely rare case, the pancreatic pseudocyst penetrated into the hepatoduodenal ligament with communication to the common bile duct, and the fluid flowed into the round ligament of the liver and next into the extraperitoneal space.

A 70-year-old man with a history of hypertension was referred to us with the complaint of abdominal discomfort. Upper gastrointestinal endoscopy revealed an irregular elevated mucosa and a submucosal tumor with delle in the duodenal bulb. Biopsy specimens revealed adenocarcinoma (the former) and hyperplasia (the latter). We could not agree with the patient about performing pancreaticoduodenectomy, so under the diagnosis of primary duodenal carcinoma, we performed resection of the bulbus and the antrum. Pathological examination showed that one of the tumors was consistent with normal Brunner's glands, Brunner's gland hyperplasia and adenocarcinoma arising from Brunner's glands. The patient's postoperative course was good, but 15 months after, he developed lymph node recurrence at the site of the pancreas head. Under the diagnosis of lymph node metastasis of duodenal cancer, we performed pancreaticoduodenectomy this time. Pathological examination confirmed our preoperative diagnosis. The patient remained well after the surgery for 2 years.

Radiofrequency ablation (RFA) is a commonly used local therapy for hepatocellular carcinoma (HCC). However, for tumors located adjacent to the Glisson's capsule in the hepatic hilar region, RFA may cause bile duct injury and may be difficult to perform using the standard procedure. We describe 2 HCC cases in which RFA was performed laparoscopically under general anesthesia while cooling bile ducts to prevent bile duct injury. An endoscopic nasobiliary drainage tube was preoperatively inserted, through which chilled saline was rapidly infused during laparoscopic RFA for HCC adjacent to the Glisson's capsule in the hepatic hilar region. The patient was discharged from hospital without intraoperative or postoperative complications. Follow-up contrast-enhanced CT revealed complete tumor cauterization and no evidence of late bile duct stenosis. This procedure is performed under general anesthesia and, unlike those performed under local anesthesia, is associated with minimal stress to patients and minimal risk of bile duct injury. - Hepatic arterial infusion immunochemotherapy with 5-FU and PEG-IFNα-2a for unresectable liver metastases from colorectal cancerHiroshi Kitaguchi; Takuya Nakai; Hajime Ishikawa; Kiyotaka OkunoBiotherapy 24 (4) 303 - 307 0914-2223 2010/07Hepatic arterial infusion immunochemotherapy with 5-fluorouracil (5-FU) and polyethylene glycol-interferon alpha-2a (PEG-IFNα-2a) was administered to patients with only liver metastases from colorectal cancer. Sixteen patients received 500mg/m2 of 5-FU and 90μg/body of PEG-IFNα-2a via a subcutaneously embedded reservoir. Fever was observed as an adverse event in all patients and was controlled by non-steroidal anti-inflammatory drugs (NSAIDs). One patient developed grade 3 leukopenia, which led to discontinuation of the treatment. Nine patients showed partial response (PR) to treatment, while 6 patients showed a stable disease (SD) condition the overall response rate was 60% (1 patient did not show PR or SD condition). Immunological tests revealed no changes in the serum levels of immune cells such as CD3-, CD4-, CD8-, and CD56-positive cells, and increased the activity of natural killer (NK) cells. These results indicate that hepatic arterial infusion immunochemotherapy with IFN - a cytokine - is a safe and effective treatment with high response rates. Further studies should be performed to evaluate the long-term outcomes, including survival rates, with this treatment.

The patient was a 55-year-old female who had multiple liver metastases of rectal cancer. This patient underwent hepatic arterial infusion chemotherapy after low anterior resection for rectal cancer. Hepatic arterial infusion was discontinued due to severe diarrhea, and the administration of UFT (300 mg/day) and LV (75 mg/day) was then begun. The carcinoembryonic antigen (CEA) level was normalized immediately after the start of this administration. One year later, liver metastases disappeared on computed tomography (CT) and a complete response (CR) was achieved. No adverse events were noted, and CR was maintained for 2 years. This therapy can serve as one of the chemotherapies for advanced colorectal cancer. - Motohiro Imano; Takao Satou; Tatsuki Itoh; Yoshifumi Takeyama; Atsushi Yasuda; Ying-Feng Peng; Masayuki Shinkai; Seiji Haji; Chikao Yasuda; Takuya Nakai; Takushi Yasuda; Haruhiko Imamoto; Kiyotaka Okuno; Hitoshi Shiozaki; Harumasa OhyanagiAMERICAN SURGEON SOUTHEASTERN SURGICAL CONGRESS 76 (1) 91 - 95 0003-1348 2010/01 [Refereed]
Mucin glycoproteins from the gallbladder epithelium are thought to contribute to the matrix or nucleus of gallstones and other biomineralization systems. The involved acidic glycoproteins have been reported in bile and gallstones. In addition, osteopontin (Opn) is a noncollagenous acidic bone matrix glycoprotein that possesses calcium-binding properties. To investigate the role of Opn in pigment gallstone formation, the involvement of Opn in pigment gallstone formation was studied immunohistochemically in the gallbladder wall and in the stones. Staining for Opn was strongly positive in the epithelium of stone-laden gallbladders and in their stones. The stone-laden gallbladders were infiltrated by macrophages, which intensely stained for Opn. Sections of the pigment stones, under low magnification, showed a lamellar pattern of Opn immunolabeling and showed a reticular pattern under high magnification. Our results indicate that Opn, an acidic glycoprotein from the gallbladder epithelium, seems to be involved in lithiasis. Opn from macrophages and/or the epithelium seems to help form the matrix protein. - Hajime Ishikawa; Takuya Nakai; Kazuki Ueda; Seiji Haji; Yoshifumi Takeyama; Harumasa OhyanagiSurgical laparoscopy, endoscopy & percutaneous techniques 19 (5) e221-4 2009/10Epidermoid cysts are the most common type of cutaneous cyst. However, their occurrence in the deep abdominal wall has not yet been reported. Here, we present the case of a 60-year-old woman who developed an epidermoid cyst in the deep abdominal wall, which was resected laparoscopically. The patient presented with right upper quadrant abdominal pain on admission to our hospital. Computed tomography revealed cholecystolithiasis and an incidentally identified well-defined hypoattenuating mass (62 x 47 x 65 mm) in the deep abdominal wall on the left side of the navel. We performed laparoscopic complete resection of the abdominal wall tumor followed by cholecystectomy. The excised specimen was a cyst covered with a smooth thin membrane and contained sludge. Histopathologic examination revealed an epidermoid cyst. This is a very rare case with no previous reports on a similar type of epidermoid cyst.

Background/Aims: Patients with hepatic malignancies are often poor candidates for resection because of the lack of hepatic reserve as a result of coexisting cirrhosis or the presence of multiple tumors. The purpose of this study was to determine the safety and efficacy of open intraoperative radiofrequency ablation of unresectable hepatic malignancies with size larger than 4cm in diameter and/or more than three in number. Methodology: Between May 2000 and September 2003, 30 patients (24 men, 6 women; age range, 5972 years; mean age, 63 years) with 51 hepatic malignancies. The maximal diameter of all tumors ranged from 1.0 to 10cm (mean +/- SD, 3.2 +/- 1.8). Results: All tumors achieved necrosis completely in a. single session. The mean follow-up from the initial ablation in this study was 18.9 +/- 10.1 months (range, 0-41). The 1-, 2 and 3-year overall survival rates were 86.1%, 71.6% and 71.6%, respectively. The 1-, 2 and 3-year disease-free survival rates were 70.9%, 37.6% and 25.1%, respectively. Conclusions: Open radiofrequency ablation is a safety and efficient approach for hepatic malignancies sized more than 4cm in diameter and/or located more than three in number. - Takuya Nakai; Takashi Kawabe; Osamu Shiraishi; Kiyotaka Okuno; Hitoshi ShiozakiHEPATO-GASTROENTEROLOGY H G E UPDATE MEDICAL PUBLISHING S A 53 (72) 947 - 949 0172-6390 2006/11 [Refereed]
Background/Aims: The incidence of delayed gastric emptying after pylorus-preserving pancreatico-duodenectomy has been reported to be 30% to 70%. Methodology: Between January 1996 and December 2002, 43 patients underwent pylorus-preserving pancreaticoduodenectomy, involving pylorotomy, in the First Department of Surgery, Kinki University School of Medicine. The first step in pylorotomy is to cut the duodenal stump obliquely. The next is incision of the pyloric sphincter along its inferior aspect. The incidences of postoperative complications and changes in body weight were collated retrospectively. Results: Delayed gastric emptying was observed in 4 patients (9.3%). However, this complication did not last more than 1 month in any patients. Two patients (4.7%) developed reflux esophagitis 1 month after surgery, but this complication had resolved by 6 months. Weight gain was noted beginning 3 months after surgery. Conclusions: Pylorus-preserving pancreaticoduodenectomy involving pylorotomy may reduce the incidence of delayed gastric emptying and preserve the long-term quality of life more than similar procedures. - Takuya Nakai; Osamu Shiraishi; Takashi Kawabe; Hideo Ota; Hiroaki Nagano; Hitoshi ShiozakiWORLD JOURNAL OF SURGERY SPRINGER 30 (7) 1338 - 1343 0364-2313 2006/07 [Refereed]
Introduction: The etiologic and prognostic factors for non-B, non-C hepatocellular carcinoma (HCC), which is defined by its seronegativity for both hepatitis B surface antigen and hepatitis C virus (HCV) antibody, remain unclear. Methods: Nonneoplastic liver tissue from 46 patients with non-B, non-C HCC were examined for hepatitis B virus (HBV) DNA and HCV RNA using in situ hybridization. Recurrence-free survival rates were compared between patients showing high or low HBV DNA expression. Other potential prognostic factors were examined as well. Results: HBV DNA was detected in nonneoplastic liver specimens from 35 patents (76.1%), whereas HCV RNA was not detected in any case. In patents with high HBV DNA group expression, recurrence-free survival rates at 1 and 5 years after onset were 68.8% and 13.8%, respectively; those with low expression had higher rates of 89.2% and 59.2%, respectively. Multivariate analysis identified high tumor stage (P = 0.042) and high HBV DNA expression (p = 0.014) as independent negative prognostic factors. Conclusions: In many patients with non-B, non-C HCC, HBV DNA in the liver appears to be involved in the carcinogenesis, with intense HBV DNA expression predicting poor outcome for patients with these cancers. - 大腸癌肝転移の治療戦略中居 卓也; 奥野 清隆消化器科 科学評論社 42 (6) 572 - 577 2006/06大腸癌肝転移、特に両葉多発肝転移治療に従来であれば肝切除不可能で肝動注化学療法が適応とされる症例に、肝切除にRFAを併用させたり、肝動注後腫瘍が縮小し肝切除可能となれば切除し、その両者の予後は3年生存率30%以上に改善した。RFAの局所制御能は肝細胞癌と同じで3cm以下の腫瘍が適応とされた。

A venous cuff technique was applied only for venous drainage in orthotopic small bowel transplantation of rats. Rates of technical failure (death within 4 days) and in clinical signs were compared between the groups with (group A) and without (group B) venous cuff technique. Technical failures with and without venous cuff technique were 5% and 25%, respectively. Mean survival days, excluding deaths from technical failure, were 9.2 +/- 2.3 in group A and 8.1 +/- 2.6 days in group B. No significant differences were observed in mean survival days or in weight loss between the two groups. Acute rejection was the cause of death in both groups. Since the model with venous cuff technique showed low mortality, it could be widely employed in small bowel transplantation studies.

Research Themes
- Japan Society for the Promotion of Science:Grants-in-Aid for Scientific ResearchDate (from‐to) : 2011 -2013Author : ISHIKAWA Hajime; OKUNO Kiyotaka; TAKEYAMA Yoshifumi; NAKAI TakuyaWe performed the peptide-cocktail vaccination for hepatocellular carcinoma. The vaccine mixes an adjuvant with WDRPUH, FOXM1, MELK, HJURP-derived and HLA-A24-restricted epitope peptides. The vaccine was tried on five liver cancer patients till the present. One patient had reduction of the tumor. The other patient had SD. Although adverse events were skin induration and gastrointestinal bleeding, both were two or less grades.

In a hepatectomy model, appearance of self-injuring lymphecytes, accelerated expression of MHC antigens, and infiltration of CD8-positive cells in the liver had been demonstrated in an early stage of regeneration. In our study of transplantion of small intestine, migration of graft-antigen presenting cells into the liver via the portal vein and rejecting reaction there were observed. In these points, the environment for intestine grafting seems to be similar to that for liver regeneration, and an immunological organ-correlation between the liver and the small intestine was demonstrated. Therefore, we considered that liver regeneration phenomenon is a rejecting reaction against self-hepatocytes. However, in a hepatectomy model, no difference was found between the small intestine and the liver at the time of liver regeneration with respect to the dynamics of CTL, NK activity or NKT cells that sho specific distribution in the small intestine and the liver. On the other hand, as clinical application of liver-regeneration enhancement therapy, a hepatectomy model was fed with food containing glutamine at different concentration (0, 2 or 4%). Consequently, on the 7th day after operation, LBR (ratio of weight of the remaining liver to that of body weight) that indicates lliver regeneration in the 2% group was higher than that in the 0% or 4$ group. Since NK activity was significantly high in the 2% group in comparison with that in the 0% and 4% groups, the optimum glutamine concentration was 2%. For the purpose of demonstrating the mechanism of liver regeneration in vivo, cell-growth factors, cell-cycle control factors and transcription-regulating factors pertaining to liver regeneration were examined using a DNA expressions in a short time in analyses of cancer-related genes. Consequently, activation of transcription factors such as STAT3, C/EBPs, Bel-x and IGF was suggested.

However, the immunologic mechanisms responsible for rejection and GVHD are still unclear. Fully allogeneic orthotopic small bowel transplantation from Brown-Norway to Lewis rats were performed using a venous-cuff technique. Signs of rejection and GVHD and host survial time following FK506 administration were recorded. Natural killer (NK) cell activity and CTL (cytotoxic T lymphocyte) activity in the liver, spleen and mesenteric lymph node (MLN) of the host and MLN of the graft were measured. Rats not given FK506 developed acute rejection. Rats given FK506 at a dose of 0.5mg/kg/day developed temporary GVHD without evidence of rejection and survived more than 100 days. Rats given 1.0mg/kg/day of FK506 did not develop GVHD.However, some of them developed chronic rejection and died within 84 days. Immunologic analysis demonstrated that acute rejection occurred in rats that showed high levels of NK and CTL activities, and that temporary GVHD occurred when the NK activity was greater than the CTL activity. These activities were greater in the liver and the graft MLN. Although FK506 suppresses both NK and CTL activities, different doses of the agent result in different immunosuppressive effects. GVHD and rejection after fully allogeneic small bowel transplantation occur depending on NK and CTL activities.
