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)
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)
< 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 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)
BACKGROUND Although the fecal elastase-1 test is a satisfactory pancreatic exocrine function test, breath tests that use stable isotopes have been developed recently as alternatives. We evaluated the usefulness of a (13)C-labeled mixed triglyceride breath test for assessing pancreatic exocrine function after pancreatic surgery. METHODS The breath test and(More)
BACKGROUND AND OBJECTIVES Middle pancreatectomy is infrequently performed in selected patients. The rationale is to preserve pancreatic function. This study evaluates a technique, operative outcomes, and long-term exocrine and endocrine pancreatic function of the middle pancreatectomy procedure. METHODS Nineteen patients who underwent middle(More)
The aim of this study was to identify a preferable procedure reducing the incidence of delayed gastric emptying (DGE) after pylorus-preserving pancreatoduodenectomy (PPPD). Data on 132 consecutive patients with pancreatobiliary disease, who underwent PPPD, were collected retrospectively. A retrocolic Billroth I type reconstruction (B-I group) and an(More)
We report herein on the follow-up of ten consecutive patients who underwent perineal rectosigmoidectomy, and discuss the indications, surgical technique, and outcomes of this procedure. The median age of the patients was 79 years, with a range of 26 to 85 years, and eight patients had complicating medical conditions. Of five patients who underwent this(More)
The aim of this study was to assess the long-term (greater than 2 years) results of seton drainage on anal fistulae in patients with Crohn's disease. Methods: Between September 1990 and September 1999, 32 patients with Crohn's disease underwent seton drainage for complex anal fistulae. The median follow-up time in these patients was 62 months (range, 25–133(More)
