The prognosis of patients with cholangiocarcinoma is unsatisfactory. Therefore, evaluation of prognostic factors and establishment of new therapeutic strategies are needed to improve their long-term survival. The aim of this study was to identify useful prognostic factors for patients with intrahepatic, hilar, and distal cholangiocarcinoma. Records of 127(More)
BACKGROUND/PURPOSE It is important to predict the development of clinically relevant pancreatic fistula (grade B/C) in the early period after pancreaticoduodenectomy (PD). This study has been carried out as a project study of the Japanese Society of Hepato-Biliary-Pancreatic Surgery (JSHPBS) to evaluate the predictive factors associated with clinically(More)
OBJECTIVE The aim of this study was to evaluate the efficacy of adjuvant gemcitabine plus S-1 chemotherapy after aggressive surgical resection for advanced biliary carcinoma. SUMMARY BACKGROUND DATA No effective adjuvant therapy for advanced biliary carcinoma has been reported although its prognosis is extremely poor. METHODS Medical records were(More)
Preoperative biliary drainage (PBD) is associated with bacterial contamination of bile, but the effects of PBD on morbidity after pancreatoduodenectomy remain controversial. The aim of this study was to characterize bile contamination to develop successful specific antibiotic prophylactic strategies for pancreatoduodenectomy. Ninety-one consecutive patients(More)
BACKGROUND This study evaluated the prognostic significance of the number of metastatic lymph nodes and the ratio of metastatic nodes to total number of examined lymph nodes (lymph node ratio, LNR) after resection of pancreatic carcinoma. STUDY DESIGN Records of 119 consecutive patients with pancreatic ductal carcinoma, who underwent R0 or R1(More)
BACKGROUND In recent years, nonalcoholic fatty liver disease (NAFLD) after pancreatoduodenectomy (PD) has become increasingly problematic. Our aims were to clarify the relationship between NAFLD and postoperative pancreatic exocrine function and to identify the risk factors for NAFLD after PD. METHODS Patients who underwent PD (n = 104) were assessed with(More)
< 0.05). The surgical site infection rate was 18% in group 1 and 13% in group 2. Organisms isolated from the sites of postoperative infections were not identical with those from the peritoneal fluid. This relatively brief course preparation minimized the emergence of resistant strains. However, in spite of the colonic bacterial burden and the intraoperative(More)
The prognosis for patients with advanced gallbladder carcinoma is dismal despite aggressive surgical resection. The aim of this study is to determine useful prognostic factors for patients with gallbladder carcinoma following aggressive surgical resection. Medical records of 62 patients with gallbladder carcinoma who underwent surgical resection were(More)
The aim of the present study was to clarify the prognostic impact of para-aortic lymph node metastasis in pancreatic ductal adenocarcinoma. Medical records of 103 consecutive patients with pancreatic ductal adenocarcinoma, who underwent pancreatic resection with regional and para-aortic lymph node dissection were reviewed retrospectively.(More)
The aim of this study was to identify useful prognostic factors in patients undergoing pancreatoduodenectomy for distal cholangiocarcinoma. The records of 36 patients with distal cholangiocarcinoma undergoing pancreatoduodenectomy were retrospectively reviewed. Potential clinicopathological prognostic factors that may affect survival were examined by(More)
