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...

Intraductal papillary neoplasm of the bile duct (IPNB) represents biliary papillary tumors mainly growing and is considered to be of relatively low-grade malignancy. Here we report a case of IPNB in whom the poorly differentiated component deeply infiltrated the bile duct wall. A 77-year-old male had an invasive carcinoma of the bile duct 3 cm in size. He underwent right hemihepatectomy with co...

INTRODUCTION Mixed adenoneuroendocrine carcinomas (MANECs) of the distal bile duct are extremely rare, and only a few cases have been reported in the English literature. PRESENTATION OF CASE An 82-year-old man was referred to our hospital for increasing biliary enzymes. Abdominal computed tomography (CT) showed enlargement of the intrahepatic bile ducts and stenosis of the distal bile duct. E...

HYPOTHESIS Resection of the gallbladder together with the dilated bile duct is the preferred treatment for pancreaticobiliary maljunction (PBM) with bile duct dilatation, whereas this treatment for PBM without bile duct dilatation is still controversial. DESIGN Retrospective study of 196 patients from January 1979 to November 2004. SETTING Two university hospitals. PATIENTS One hundred ni...

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 Major bile duct injury is an important therapeutic problem that can be associated with simultaneous injury to the hepatic artery. Limited information exists regarding the course of patients who have combined bile duct and arterial injuries. OBJECTIVE To compare the management and outcome of isolated bile duct injuries with bile duct and hepatic artery injuries. PATIENTS AND METHO...

ly rare anomaly of the biliary tract system, which was first described by Vesalius in 1543 [1]. Recent advances in radiologic examinations have facilitated the correct diagnosis and management of this condition, but visualization of the anomaly using cholangioscopy has not been reported [2]. We report the finding of a double common bile duct with ectopic drainage into the duodenal bulb, which w...

Adenomyomatous hyperplasia is rarely found in the extrahepatic bile duct. A 54-year-old man was referred to our center with a diagnosis of extrahepatic bile duct stenosis which had been detected by endoscopic retrograde choloangiopancreatography. Abdominal computed tomography revealed thickening of the wall of the middle extrahepatic bile duct, however no malignant cells were detected by cytolo...

We present a case of liver metastasis of renal cell carcinoma (RCC) presenting as an intraductal tumor thrombus of the common bile duct. A 62-year-old man was admitted with jaundice. He had undergone right nephrectomy for RCC 8 years previously, and had been administered interferon alfa for lung, bone, and liver metastases for these 3 years. Abdominal enhanced computerized tomography (CT) discl...

Bile duct stones from 42 patients were morphologically and chemically analysed. The calculi from 27 patients had important primary bile duct stone (PBDS) features, consisting of a general ovoid shape and fragile structure, with alternating light and dark brown pigmented layers on cross-section. Chemically these stones contained low levels of cholesterol, with high levels of bilirubin and calciu...
