Through aggregating tubules of increasing diameter, the bile leaves the liver and reaches the upstream (proximal) component of the common bile duct. Apparently, the common bile duct beyond (distal to) the gallbladder tends to normally have a greater tone so that the bile backs up into the gallbladder. When bile enters the duodenum (the first ...
Biliary atresia, also known as extrahepatic ductopenia and progressive obliterative cholangiopathy, is a childhood disease of the liver in which one or more bile ducts are abnormally narrow, blocked, or absent. It can be congenital or acquired. Biliary atresia is the most common reason for pediatric liver trasplantation in the United States. [2]
Leakage of bile and destruction of the biliary tree are the most common causes of biloma. Destruction of the billary tree means that there is a blockage in the pancreatic or bile duct. Bile ducts are vessels that carry from the liver to the gallbladder. When bile becomes blocked, pancreatic juices cannot be transported to the intestines.
Bile duct obstruction, which is usually present in acute cholangitis, is generally due to gallstones. 10–30% of cases, however, are due to other causes such as benign stricturing (narrowing of the bile duct without an underlying tumor), postoperative damage or an altered structure of the bile ducts such as narrowing at the site of an anastomosis (surgical connection), various tumors (cancer ...

PSC increases the risk of various cancers, including liver cancer , gallbladder carcinoma , colorectal cancer , and cholangiocarcinoma .
