Two Cases of Hemobilia Associated with Common Bile Duct Stones / 대한소화기내시경학회지

ABSTRACT

Hemobilia is a disease caused by injury or conditions that cause the abnormal communication between intrahepatic blood vessels and biliary tract, resulting in leakage of blood into the biliary tract. In the past, trauma had been the most common cause of hemobilia. However, with the increasing invasive procedures in the hepatobiliary tract, iatrogenic origin has become the major cause of hemobilia. Also, non-traumatic etiologies of hemobilia include vascular malformation such as aneurysm, gallstone, inflammation, biliary tumor, hepatocellular carcinoma and coagulopathy. Among these non-traumatic etiologies, choledocholithiasis is a rare cause of hemobilia. The authors have experienced two cases of hemobilia caused by choledocholithiasis, which was diagnosed by abdominal ultrasonography, abdominal CT and duodenoscopy. Both patients were treated by the endoscopic sphincterotomy and stone removal with basket.
