Conspicuous pathologic features of chronic liver allograft rejection include bile duct loss and chronic obliterative arteriopathy. A quantitative histometric analysis was performed to document the extent of bile duct loss, the size of the "vanished" ducts and the extent of chronic obliterative arteriopathy and to determine whether there was any relationship between chronic obliterative arteriop...

Non-traumatic perforations of the bile ducts are unfrequently encountered entities, all the more when they affect the intrahepatic bile ducts, exteriorizing their biliary content in the great peritoneal cavity. Reporting such a case has determined the authors to perform a careful overview of the cases present in the literature. An observation that can be made based on these is that the obstruct...

During liver development, hepatoblasts differentiate into hepatocytes or biliary epithelial cells (BEC). The BEC delineate the intrahepatic and extrahepatic bile ducts, and the gallbladder. The transcription factors that control the development of the biliary tract are unknown. Previous work has shown that the onecut transcription factor HNF6 is expressed in hepatoblasts and in the gallbladder ...

We report here on an extremely rare case of duplicated extrahepatic bile ducts that was associated with choledocholithiasis, and this malady was visualized by employing the minimum intensity projection images with using multi-detector row CT. The presence of duplicated extrahepatic bile ducts with a proximal communication, and the ducts were joined distally and they subsequently formed a single...

a 65-year-old female presenting with hepatobiliary cystadenoma (hc) comprised of multiple cysts in the liver and a non-specific epigastric pain is reported herein.  ultrasound study demonstrated dilated common bile duct (cbd) and intrahepatic bile ducts, plus two spherical stone-like bodies filling defects in the proximal cbd. sphincterotomy and basket performed for the patient were not success...

Papillary tumors of the bile ducts are intraductal tumors with numerous minute frondlike papillary projections. Some intraductal papillary tumors of the bile ducts produce a large amount of mucin that disturbs bile flow and causes severe biliary dilatation. In the presence of a tumor of this subgroup, the entire biliary tree is dilated; segmental or lobar bile ducts are dilated disproportionate...

To study the impairment of cholangiocyte primary cilia caused by prolonged cold preservation and its correlation with graft cholangiopathy after orthotopic liver transplantation (OLT). Subjects were 60 male Wistar rats that were divided into 2 groups: a control group (n = 30) receiving a donor liver preserved for 1 h and a study group (n = 30) receiving a donor liver preserved for 12 h. A two-c...
