Objective:To evaluate the efficacy and application of combined laparoscopic and duodenoscopic transcystic duct for common bile duct (CBD) exploration and stone extraction (LTCBDE).
Methods:Eighty-two patients, diagnosed as gallbladder and CBD stone(s) by MRCP before operation,  were treated by LTCBDE.
Results:LTCBDE was successfully carried out in all the cases and no case was converted to laparotomy. The amount of hemorrhage during operation varied from 30 to 80mL. There were no serious complictions, and hospital stay was 4-6 d. Follow-up of the 82 cases for 3 months to 1 year showed no case of bile duct stricture or recurrent stones.
Conclusions:LTCBDE is the best operation to treat cholecysto-and choledocholithiasis when the suituble indications are followed
