Abstract

Endoscopic retrograde cholangiopancreatography (ERCP) was carried out on 19 patients with hydatid cyst of the liver, either before or after operation. Cholangiographic findings included biliary tract obstruction in 8 cases, intrinsic compression in 4 cases, laminated membranes or daughter cysts in the biliary tree in 3 cases, perforation into the biliary tract in 2 cases, stricture in the biliary ductal system in 1 case, and biliary fistula in the remaining case. Biliary tract obstruction was secondary to chemical cholangitis by formalin in 2 patients. ERCP is a useful procedure in patients with suspected intrabiliary rupture or when symptoms occur after surgical removal of the cyst.
