Biliary bleeding

Biliary hemorrhage, or hemobiliary disease, is a pathological communication between intrahepatic or extrahepatic blood vessels and the biliary tract caused by various reasons. The upper gastrointestinal bleeding occurs when blood flows into the duodenum through the biliary tract. Biliary bleeding is one of the main causes of upper gastrointestinal bleeding, and it is not uncommon in China. Biliary tract hemorrhage is usually manifested as vomiting or melena, but in most cases it is a subtle, mild bleeding. According to the etiology and location of biliary tract bleeding, it is usually divided into two categories: intrahepatic and extrahepatic. Ninety percent of biliary bleeding comes from the liver, and less from the extrahepatic biliary tract and gallbladder. The case fatality rate was 7.2% to 33%.
