A 65-year-old woman developed chronic renal failure of unknown etiology and required hemodialysis. She was scheduled to undergo living-related renal transplantation from her husband. However, a cystic lesion of the liver associated with calcification, gallstones, and dilatation of intrahepatic bile ducts (B2-B3) was found by the referring hospital. Investigation of the cystic tumor was performe...

BACKGROUND The incidence of intrahepatic cholelithiasis and cholangitis has not yet been well studied postoperatively in patients with choledochal cysts. METHODS One hundred three patients with choledochal cysts had operative cholangiography, underwent standard excision of a choledochal cyst with Roux-en-Y hepatico-jejunal anastomosis, and were at a mean follow-up of 12 1/2 years. The inciden...

bar pain and showed multiple small hepatic nodules in a previously asymptomatic 37-year-old woman. Liver function tests and tumor markers were normal. Magnetic resonance imaging (MRI) demonstrated multiple highly intense, regular nodules (less than 15 mm) with no communication to the bile tree (Fig. 1A). After intravenous gadolinium DTPA, some nodules showed peripheral enhancement from hepatic ...

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...

A 13-year-old spayed female Siamese cat was submitted for necropsy following unsuccessful treatment for obstructive jaundice. Histopathologic examination revealed an adenocarcinoma of the hepatopancreatic ampulla. The carcinoma obstructed the pancreatic and common bile ducts entering the ampulla, resulting in severe diffuse acinar degeneration, atrophy and fibrosis of the pancreas, and dilatati...

Intraductal papillary mucinous neoplasms are known malignant lesions of pancreas but recently a similar tumor has been reported and recognized by WHO in 2010 which involves the bile ducts. The involvement of common bile duct by this malignant tumor is extremely rare. Intraductal papillary mucinous tumors of bile ducts have been found to have much better prognosis than the other cholangiocarcino...

In a case operated on for calculous jaundice the right and left hepatic ducts drained directly into the gallbladder and the cystic duct was the only route by which hepatic bile reached the duodenum. Exploration of the inside of the gallbladder was a crucial step for the discovery of the anomaly. Continuity of bile drainage was secured by the preservation of a portion of the gallbladder which co...
