Bile duct injury during laparoscopic cholecystectomy: Mechanism of injury, prevention, and management

Although several studies have shown a low incidence of bile duct injuries during laparoscopic cholecystectomy, concerns remain because of the sustained increase in the number of referrals for biliary reconstruction after the procedure. Twenty-one patients have been referred to our institution because of major bile duct injuries after laparoscopic cholecystectomy. The injury was recognized during the laparoscopic procedure in only 6 of the 21 (29%). Nineteen patients underwent hepaticojejunostomy at least once, one patient required hepaticojejunostomy and repair of a choledochoduodenal fistula, and one patient needed repair of a biliary colonic fistula. Hepaticojejunostomy above the bifurcation was required in 10 patients (50%), at the bifurcation in 3, and below the bifurcation in 7. Nine of the eleven patients in whom the initial repair was performed at the local hospital presented with early stricture (median 7 months). The common denominator of the development of bile duct injuries during laparoscopic cholecystectomy is the failure to identify the structures of the triangle of Calot. Specific steps during laparoscopic cholecystectomy to avoid bile duct injuries are described. Expertise in hepatobiliary surgery appears to optimize results of biliary reconstruction.
