ABSTRACT

Objective To investigate the clinical significance of the treatment of intrahepatic bile duct stones with fiber choledochoscope combined with intraoperative ultrasound.Methods The clinical data of 185 cases with intrahepatic bile duct stone were analysed retrospectively,included 96 cases with stone removal by fiber choledochoscope intra-and post-operatively(choledochoscope group),and 89 cases with stone removal by fiber choledochoscope combined with intraoperative ultrasound(combined group).Results The rateo of bile duct retained stones in choledochoscope group(9.38%) was higher than that in combined group(2.08%)(P=0.041),and the rate of bile duct recurrent stones in choledochoscope group(12.34%) was higher than that in combined group(3.61%)(P=0.036).There was no significant differences between the two groups in the occarrence of cholangitis(P=0.087),but 3 cases of severe cholangitis required re-operation in choledochoscope group.Conclusions Fiber choledochoscope combined with intraoperative ultrasound can decrease the rate of bile duct retained stones and bile duct recurrent stones,and can improve the therapeutic effect.
