OBJECTIVE The purpose of this study was to evaluate whether ampullectomy can substitute for pancreatoduodenectomy (PD) in early ampullary cancer by clinicopathologic study. SUMMARY BACKGROUND DATA Although ampullectomy has been attempted in early ampullary cancer (pTis, pT1), the indication and extent of resection have not been established. METHODS Of(More)
BACKGROUND Delayed gastric emptying (DGE) is the most frequent postoperative complication after pylorus-preserving pancreatoduodenectomy (PPPD). This study was undertaken to determine which factors influence the development of DGE after PPPD. STUDY DESIGN We studied 150 consecutive patients who underwent PPPD performed by one surgeon between 1996 and(More)
OBJECTIVES The purpose of this study was to determine the outcome of surgical resection for pancreatic cancer and to characterize the clinicopathologic features of actual long-term survivors. METHODS Of the 789 pancreatic cancer patients, we retrospectively analyzed 242 patients who underwent an operation between 1985 and 1999. Surgical resection with(More)
To determine if there is any differencein pancreatic function after pylorus-preserving pancreatoduodenectomy(PPPD) according to the type of pancreatoenterostomy[pancreatojejunostomy (P-J) or pancreatogastrostomy (P-G)], weevaluated the long-term functional status of 34 patients who underwentPPPD and survived for more than 1 year without clinical evidence(More)
BACKGROUND Proliferative cholangitis (PC) leads to biliary stricture, which is the main cause of hepatolithiasis, recurrent cholangitis, and biliary cirrhosis. The aim of this study was to determine whether local delivery of paclitaxel, which inhibits cell proliferation by overstabilization of microtubules, prevents PC in a rat model. METHODS PC was(More)
BACKGROUND/AIMS Hemorrhage after pancreatoduodenectomy is a severe, life-threatening complication. This study was conducted to determine the guidelines appropriate for the prevention and management of hemorrhagic complications. METHODOLOGY We reviewed the medical records of 456 patients who had undergone pancreatoduodenectomy at our hospital between 1991(More)
The purpose of this study was to clarify the prognostic significance of transfusion following pancreatoduodenectomy for periampullary cancers. We analyzed 357 periampullary cancers from 1985 to 1997 (ampullary cancer 130 cases, distal bile duct cancer 141 cases, pancreatic head cancer 86 cases). A total of 215 (60%) of the 357 patients have received(More)
Despite the increasing number of recent reports on laparoscopic liver resection in adults, there are only rare reports on such a procedure being performed in children. The authors report here on a total laparoscopic left lateral sectionectomy that was performed in a 5-year-old girl who had a cystic tumor of the liver. The operative time was 150 minutes, the(More)
BACKGROUND Intraductal papillary mucinous neoplasms (IPMNs) are associated with a high incidence of extrapancreatic neoplasms. DESIGN Retrospective study. SETTING Tertiary care referral center. PATIENTS Sixty-one patients underwent surgical resection for IPMN between January 1, 1993, and June 30, 2004. Thirty-eight patients with mucinous cystic(More)
HYPOTHESIS Duodenal-preserving resection of the head of the pancreas (DPRHP) and pancreas head resection with segmental duodenectomy (PHRSD) can be alternatives to standard pancreaticoduodenectomy for benign periampullary lesions. DESIGN Retrospective analysis of patients requiring surgery for benign and borderline malignant tumors of the periampullary(More)
