Biliary complications associated with laparoscopic cholecystectomy: analysis of common misconceptions

Abstract

AIMS: General surgeons often express the view that the majority of biliary complications following laparoscopic cholecystectomy are caused by trainee surgeons; complications occur most often in the presence of difficult anatomy or pathology; biliary injuries occur more proximally in the biliary tree than at open cholecystectomy; most injuries are recognized at the time of surgery; and most complications can be managed non-operatively. The aim of this study was to determine if these views are substantiated in clinical practice. METHODS: Thirty consecutive patients were referred to a specialist hepatobiliary unit over a 7-year period with biliary complications following laparoscopic cholecystectomy. The mode of presentation, management and outcome of these patients were analysed. RESULTS: In 21 cases the initial operator was a consultant. Four of the 30 complications occurred in the presence of an anatomical variation or unusually difficult pathology. Only patients in whom a previous attempt at repair had been made had injuries at or proximal to the bile duct confluence; the only two deaths occurred in this group. Only 41 per cent of injuries were detected at the time of surgery and 89 per cent required further surgical intervention, hepaticojejunostomy being the most common procedure performed (75 per cent). CONCLUSIONS: The majority of bile duct injuries are not caused by trainees, do not occur because of unusual anatomy or pathology, do not occur in the proximal biliary tree, are not recognized at the time of the initial operation and often require major reconstructive procedures for their management.
