[Persistent external biliary fistula after surgery for hepatic hydatid cyst]

Post-operative persistent biliary fistulae due to hydatid cysts are difficult to manage. We report 3 cases of external biliary fistulae complicating surgery for hepatic hydatid cyst (2 cases) and intraperitoneal hydatid cyst (1 case). Endoscopic sphincterotomy was successful with closure of the fistulae in all patients. This procedure should be the first-line treatment for post-operative external biliary fistulae related to liver hydatid disease. Usually difficult and haemorrhagic surgery can thus be avoided.
