Liver resection for the treatment of post-cholecystectomy biliary stricture with vascular injury

AIM:To report experience with liver resection in a select group of patients with postoperative biliary stricture associated with vascular injury.METHODS:From a prospective database of patients treated for benign biliary strictures at our hospital,cases that underwent liver resections were reviewed.All cases were referred after one or more attempts to repair bile duct injuries following cholecystectomy(open or laparoscopic).Liver resection was indicated in patients with Strasberg E3/E4(hilar stricture)bile duct lesions associated with vascular damage(arterial and/or portal),ipsilateral liver atrophy/abscess,recurrent attacks of cholangitis,and failure of previous hepaticojejunostomy.RESULTS:Of 148 patients treated for benign biliary strictures,nine(6.1%)underwent liver resection;eight women and one man with a mean age of 38.6 years.Six patients had previously been submitted to open cholecystectomy and three to laparoscopic surgery.The mean number of surgical procedures before definitive treatment was 2.4.All patients had Strasberg E3/E4injuries,and vascular injury was present in all cases.Eight patients underwent right hepatectomy and one underwent left lateral sectionectomy without mortality.Mean time of follow up was 69.1 mo and after longterm follow up,eight patients are asymptomatic.CONCLUSION:Liver resection is a good therapeutic option for patients with complex postoperative biliary stricture and vascular injury presenting with liver atrophy/abscess in which previous hepaticojejunostomy has failed.
