Hemobilia Department of hepatobiliary disease, trauma, surgery, or systemic factors that caused the liver, biliary system, a large number of external bleeding. Bleeding is often associated with gallstones in the bile duct caused by gallstones based on the combined infection. The pathogenesis of three types:
① diffuse small intrahepatic cholangitis, bile duct inflammation around the model. Primary lesions in the portal area, the regional inter-lobular and lobular control communication between the venous phase occurs over a small bile duct fistula, extensive bleeding together into a small duct biliary tract bleeding.
② liver abscess type. Multiple biliary liver abscess collection of National Cheng Kung University abscesses, pus corrosion hepatic artery or portal vein branches, resulting in hemobilia.
③ bile duct ulcer type. Acute obstructive suppurative cholangitis, the obstruction of bile duct epithelial off the top of the formation of multiple ulcers, ulcers penetrate adjacent hepatic artery, portal vein and biliary tract bleeding occurred.
