Reoperative surgery for postcholecystectomy bile duct injuries.

BACKGROUND

Surgical repair for a postcholecystectomy bile duct injury can be complicated by the development of an anastomotic stricture which necessitates re-intervention. The authors reviewed their experience with patients requiring re-operation after unsuccessful surgical repair of the bile duct injury, to analyze the possible causes of the failure of the operative procedure and the long-term outcome following revisional surgery.

METHODS

Retrospective analysis of the records of 41 patients referred to a tertiary care center for the management of recurrent stricture following surgical repair performed for a postcholecystectomy bile duct injury.

RESULTS

Before referral, 69 operative procedures had been performed on these 41 patients. Factors likely to be associated with increased chances of failure of the biliary reconstructive procedures included presentation with cholangitis after the biliary injury, no cholangiographic study before the surgical repair and surgical intervention within 3 weeks of the injury. Thirty-seven (90%) patients were found to have strictures at or above the level of confluence of right and left hepatic ducts, while at the time of the index repair only 12 (29%) patients had an injury at that level. Revisional surgery in all the patients was a Roux-en-Y hepaticojejunostomy. One patient died, 2 patients with multiple previous operations developed recurrence and needed intervention again. Over a mean follow-up period of 4.2 years, 90% patients had a satisfactory outcome.

CONCLUSION

Development of recurrent stricture following surgical repair of a postcholecystectomy biliary injury can be related to the technique and timing of the surgical procedure, the complication may therefore be avoidable in some patients. In experienced hands the results of revisional surgery are good but are adversely affected as the number of previous repairs increases.
