Abstract:Objective: To summarize the experience in choledochoscopic treatment of postoperative intrahepatic duct stones and strictures, so as to improve the therapeutic efficacy of this condition. Methods: The clinical records of 697 patients with postoperative intrahepatic duct stones and strictures undergoing choledochoscopic treatment via T-tube sinus tract from January 2000 to December 2012 were reviewed and, the technical essentials were analyzed and therapeutic efficacy was evaluated. Results: The stones were completely removed in 672 patients and rate of complete stone removal was 96.4%. One thousand three hundred and six intrahepatic duct strictures were detected by choledochoscopy, 1 297 of which were dilated, and the stricture-resolution rate was rate was 99.3%. The epithelial cells of the bile duct recovered in the patients after biliary stricture dilation and stone removal. Nine patients developed severe complications that were all resolved by appropriate treatments. Conclusion: The standardized choledochoscopic treatment can effectively resolve the postoperative biliary strictures and remove the intrahepatic stones; detection and management of the intrahepatic strictures is the major advantage of choledochoscopic technique, but they should be treated specifically according to the stricture types. Resection of atrophic hepatic segment and intraoperative stone removal are still the important treatment methods for intrahepatic duct stones.
