A promising method for repairing low-level biliary strictures after cholecystectomy

Abstract

The purpose of this study is to introduce and evaluate a new technique of repairing bile ducts by the tubular gastric wall with a vascularized pedicle. Both the end-to-end bile duct repair and Roux-en-Y hepatoenterostomy have limitations in the treatment of benign bile duct strictures after cholecystectomy. There are no other good choices to manage these cases, especially the bile duct transection injuries or partly missing common bile duct or hepatic duct. Eleven patients with partly missing common bile ducts in the Chinese People's Liberation Army General Hospital between January 2007 and December 2012 were retrospectively analyzed. The study comprised 8 females and 3 males, whose age ranged from 29 to 56 years. All patients underwent successful bile duct repair. The time of operations ranged from 210 minutes to 240 minutes. The maximal blood loss was less than 220 ml. There was no perioperative mortality and no case of gastric fistula. Postoperative complications occurred in 3 patients, including wound infection, bile leakage, and erosive gastritis. All complications were cured by conservative treatment. The mean follow-up time was 42 months. One patient was classified as Terblanche's grade II and 10 patients were classified as Terblanche's grade I. The observations indicate that this technique is a feasible and effective choice to manage low level biliary stricture after cholecystectomy, especially suitable to repair bile duct transection injuries or partly missing common bile duct or hepatic duct.
