BACKGROUND: Surgery for liver hydatidosis can result in serious morbidity and mortality. The role and efficacy of ERCP in the management of these complications was reviewed. METHODS: Retrospective analysis of 79 patients with liver hydatidosis who underwent ERCP for postoperative complications. RESULTS: All patients with biliary fistulas (n = 50) were managed by endoscopic sphincterotomy, although 9 (18%) also required a biliary endoprosthesis. Surgical reintervention was avoided in 46 (92%) patients with subsequent surgery required in only in 4 (8%). The mean time to fistula closure was 13.3 days. Patients with daughter cysts in the bile ducts (n = 7) were also treated by endoscopic sphincterotomy and evacuation of obstructing cyst material. Seven patients with elevated liver enzymes or biliopancreatic symptoms but normal ERCP findings also underwent endoscopic sphincterotomy with normalization of biochemical tests. CONCLUSIONS: ERCP is valuable for detecting and treating postoperative biliary complications after surgery for hepatic echinococcal disease. In the majority of patients, endoscopic sphincterotomy allows healing of postoperative external biliary fistulas, and should be performed as early as possible. In some cases, a biliary prosthesis may be required. Endoscopic sphincterotomy also enables clearing of the bile ducts of hydatid remnants.
