Endoscopic Therapy of Biliary Injury After Cholecystectomy
Overview
Affiliations
Background: Iatrogenic bile duct injury (BDI) is a common complication after cholecystectomy. Patients are mainly treated endoscopically, but the optimal treatment method has remained unclear.
Aims: The aim was to analyze endoscopic treatment in BDI after cholecystectomy and to explore endoscopic sphincterotomy (ES), with or without stenting, as the primary treatment for an Amsterdam type A bile leak.
Methods: All patients referred to Helsinki University Hospital endoscopy unit due to a suspected BDI between the years 2004 and 2014 were included in this retrospective study. To collect the data, all ERC reports were reviewed.
Results: Of the 99 BDI patients, 94 (95%) had bile leak of whom 11 had concomitant stricture. Ninety-three percent of all patients were treated endoscopically. Seventy-one patients had native papillae and a leak in the cystic duct or peripheral radicals. They were treated with ES (ES group, n = 50) or with sphincterotomy and stenting (EST group, n = 21). There was no difference between the closure time of the fistula (p = 0.179), in the time of discharge from hospital (p = 0.298), or in the primary healing rate between the ES group and the EST group (45/50 vs 19/21 patients, p = 0.951).
Conclusion: After the right patient selection, the success rate of endoscopic treatment can approach 100% for Amsterdam type A bile leak. ES is an effective and cost-effective single procedure with success rate similar to EST. It may be considered as a first-line therapy for the management of Amsterdam type A leaks.
