ABSTRACT

Objective To investigate the effectiveness of choledochoscopy and duodenoscopy in the treatment of residual calculus of the intrahepatic bile duct. Methods Clinical data of 573 cases of choledochoscopy and 36 cases of duodenoscopy from February 1985 to June 2004 were analyzed. Results Stones were completely removed under choledochoscope by way of T-tube sinus tract in 96.02% of patients (507/528) and by way of subcutaneous blind loop in 84.62% of patients (22/26). Percutaneous transhepatic choledochoscope placement was successfully conducted in 84.21% of patients (16/19) and stones were completely removed in 78.95% of the patients (15/19). The success rate of duodenoscopic cholangiography was 91.67% (33/36) and stones were completely removed under duodenoscope in 80.56% of patients (29/36). Conclusions Treatment of residual and recurrent calculus of the intrahepatic bile duct by choledochoscopy and duodenoscopy is effective and convenient.
