Abstract

Choledochal web is an extremely rare disease and it is frequently associated with bile duct stone that causes biliary obstruction and cholangitis. Most cases of choledochal web have been found incidentally during a surgical procedure or on autopsy because of its rare incidence and the absence of specific clinical manifestations. Yet making an early diagnosis has become feasible with the development of radiologic studies. All twelve cases of choledochal web, reported in Korea, were located in the extrahepatic duct, and were diagnosed with an operation, endoscopic retrograde cholangiopancreatography or percutaneous transhepatic cholangiography. We report here on a case of intrahepatic choledochal web that was well visualized by percutaneous transhepatic choledochoscopy and it was treated with balloon dilatation.
