Endoscopic therapy for patients with a post-operative biliary leak

Abstract

Twenty-three patients with a post-operative biliary leak were treated by various endoscopic methods and results were analyzed. Leaks occurred at the cystic duct in 13 patients, at the common duct in 6 patients, and at an anomalous branch of the right hepatic duct in 4 patients. Treatments included sphincterotomy alone (4 patients), stent alone (6 patients), sphincterotomy and stent (12 patients), and sphincterotomy and nasobiliary drainage catheter (1 patient). Five patients also had supplemental percutaneous catheter drainage of a biloma. All treatments were completed successfully in the absence of major morbidity, and permanent closure of the leak occurred in 100% of cases. Endoscopic therapy for patients with a post-operative biliary leak is safe and effective and should be recommended before surgical re-exploration.
