The aim of this study was to examine whether the type of bilioenterostomy enhances biliary carcinogenesis in the hamster model. Syrian hamsters were divided into the following groups; simple laparotomy (control group), cholecystoduodenostomy with dissection of the extrahepatic bile duct on the distal end of the common duct (CDDB group) and cholecystoileostomy with dissection of the extrahepatic...
Background: The incidence of complications of laparoscopic cholecystectomy has increased dramatically since the introduction and widespread use of laparoscopic cholecystectomy in 1990. Bile duct injuries are among the most important complications of this approach. Methods : From January 1998 to January 2002, a total of 155 laparoscopic cholecystectomy were performed at the Loghman Medical Cent...
Common bile duct perforation has been reported in adults after invasive procedures. Spontaneous common bile duct perforation is a rare entity as a cause of acute abdomen in adults. A few cases due to choledocholithiasis have been reported as a cause of spontaneous perforation. We report an adult patient who presented with acute abdomen after spontaneous common bile duct perforation due to unkno...
By inducing hepatic parenchymal atrophy through deviation of the portal blood flow and, at the same time, bile-duct proliferation by common bile-duct obstruction, proliferating bile ducts were found to occupy almost the whole of the lobe affected by both these procedures. The lobe, therefore, appeared to be composed al most completely of bile-duct cells, with only very few surviving hepatic cel...
Percutaneous drainage of the bile ducts is an established procedure for malignant obstructions, in which a histological diagnosis is often not obtained. We describe the biopsy technique of obstructive lesions through biliary drainage access, using a 7F endoscopic biopsy forceps, widely available; some are even reusable. This technique applies to lesions of the hepatic ducts, of the common hepat...
