Trends in bile duct injuries from laparoscopic cholecystectomy

Abstract

Bile duct injuries are a serious complication of cholecystectomy. Laparoscopic cholecystectomies (LC) were originally associated with an increased incidence of injuries. Patients referred to a tertiary center were reviewed to assess the trends in the number, presentation, and management. Seventy-three patients were referred over a 6-year period with a maximum of 17 patients referred in 1992, but the number has not declined substantially over time. The persistent number of referrals is a consequence of ongoing injuries. One third of injuries were diagnosed at LC, and the use of cholangiography has not increased. The number of cystic duct leaks has not decreased and they represent 25% of all cases. The level of injury has remained unchanged with Bismuth types I and II in 37% and types III and IV in 38%. Excluding patients with cystic duct leaks, 58% were referred after a failed ductal repair. Definitive treatment with biliary stenting was successful in 37%, and 34 patients (47%) required a biliary-enteric anastomosis. Complications occurred in 18 patients (25%) including seven with postoperative stricture or cholangitis. No biliary reoperations have been performed at a mean follow-up of 36 months.
