Abstract

Rackground/Aims: Mechanisms of hepatomo-in(luced biliary obstruction include pedunculated tumor extension, obturating bemorrhagic clot and tumor debris, direct invasion of the biliary system by a tumor nodule, and metastatic lymph node compression of the major ducts in the porta hepatis. Usually, the diagnosis has been an unexpected finding at surgery or postmortem and preoperative diagnosis is seldom made, it is very meaning to find out thc characteristics to predict the hepatoma-induced biliary obstruction. This study I, conducted to elucidnte the findings in patients with hepatoma-induced obstructive jaundice. Methods: We reviewed clinical, radiological and surgical findings in six cases of hepatocellular carcinoma who showed jaundice due to obstruction of the extrahepatic bile duct and confirmed histologically from 1990 to 1993, and analyznl the cholangiographic fingdings. Results: The mean age of the patients was 54.2 years and 4 were males, 2 females. The common cholan-giographic tmdings of a11 case. Wvre bulky intraluminal tilling defects, which expand the biliary trce by tumor itself. Thesc defects somewhat resemble a wine- g1ass appearance. The margins of defects were slightly lobulated and somewhat irregular. Defects occurred at various level from the intrahepatic raclicle to the
