biliary papillomatosis is a disorder characterized by numerous adenomatous polyps of variable distribution and extent in intrahepatic bile ducts. it should be considered as a premalignant condition because a high proportion of the lesions undergo malignant transformation. in this report, we present a patient with abdominal pain and jaundice. according to his presenting signs and symptoms, ercp ...

IntroduCtIon Most hepatic biliary lesions are benign and incidentally discovered during procedures unrelated to the liver. Benign bile duct proliferations are gray–white subcapsular nodules that are often multiple, so it is not surprising that their detection results in more liver frozen sections than any other finding. In contrast, a diagnosis of intrahepatic cholangiocarcinoma is almost alway...

Giant staghorn common bile duct (CBD) calculi are usually uncommon but can be found in patients with oriental cholangiohepatitis. The size of stone can vary from few millimetres to several centimetres. These are usually pigment stones and patients can present with pain, jaundice and fever or some times Reynold's pentad. Primary bile duct stones form within the bile ducts and usually are of brow...

background: rupture into the biliary ducts is the most frequent complication of hydatid liver disease. in endemic areas of echinococcus granulosus, development of jaundice in a patient with liver cyst is initially suspected to have hydatid cyst. case presentation: a 48 year-old woman with history of asymptomatic hydatid liver cysts was admitted to the emergency department with right upper quadr...

This study aims to review the causes of intrahepatic and extrahepatic bile duct dilatation. Based on review of medical literature, a scientific classification of the causes is proposed. Intrahepatic and extrahepatic bile duct dilatation can be divided into two categories: congenital and acquired. The former includes the five classical Todani’s congenital types. The latter can be sub-classified ...

In 93 consecutive cases of orthotopic liver transplantation, there were 24 example of biliary obstruction and eight of bile fistula formation. Six of the obstructed livers developed biliary cast formation so extensive that the smaller intrhepatic ducts became plugged to an extent that they could no longer have been treated by surgical mena. In each of the six cases, the most important causative...

Introduction. Sclerosing cholangitis is characterized by an inflammatory and fibrotic lesion of intra- and/or extrahepatic bile ducts. When a causal mechanism of a bile duct lesion is identified, the sclerosing cholangitis is considered secondary. The vasculitis, including the Behçet disease, is cited as a probable cause of the ischemia and the sclerosing cholangitis. No cases of extrahepatic s...

Immunoglobulins were isolated from the serum or ascitic fluid of Lou/Wsl rats bearing plasmacytomas and labeled with 125I. When labeled IgA was injected i.v. it disappeared from the blood serum much more rapidly than IgG2 so that after 3 h less than 10% remained. This rapid disappearance of the injected IgA was not seen in rats with ligated bile ducts. In rats with cannulated bile ducts, the la...

The biliary tree system consists of two divisions: intrahepatic bile ducts and extrahepatic bile ducts. The development of the biliary tree, and secondarily the liver, shares a common origin with ventral pancreas. A common progenitor for liver, biliary duct system, and ventral pancreas exists at early stages of development, when the anterior definitive endoderm is forming the foregut. Several s...
