ABSTRACT
Objective To evaluate the efficacy of X-ray guided choledochoscopy via T tube tunnel and interventional treatment of residual bile duct stones.Methods Cholangiography was performed in patients suspected of residual bile duct stone with choledochoscopy via the remaining T tube tunnel,and data of 45 patients who received endoscopically treatment for the residual bile duct stones and bile duct stricture were analyzed.Results Seven patients' with adhesive bile duct stenosis were resolved by repeat rinse and dilation,but the procedure failed in 2 cases of bile duct stricture caused by scar;seven cases of common bile duct stone combined with gradeHand Ⅲ multiple hepatic cholelith were removed within 1.5 h:six cases of hepatic bile duct narrowing with multiple cholelith were taken out in 1.0 hour;six cases of grade Ⅱ and Ⅲ multiple massive choledocholith were removed with lithotrity for over 2.0 h:six cases of grade Ⅱ-Ⅳ cholelith were eliminated within 1.5 h:six cases of hepatobiliary stone were removed successfully in 30 min.Stones in 3 cases of multiple stones with intrahepatie bile duct stenosis were not taken out due to bile duct stricture;stones in 2 cases of gradeⅡand Ⅲ multiple choledocholith were not removed for T tube tunnel bleeding.Conclusion X-ray guided choledochoscopy is convenient and effective to remove residue cholelith.
