Objective:To investigate the effect of endoscope assisted microincision cholelithotomy(EMC) in the treatment of gallstone. Methods: The clinical data of 86 patients with gallbladder stone treated by EMC were analyzed retrospectively.Of them, 63 cases were follwedup and studied. Results :All eightysix patients were successfully operated on and discharged, no operative complications occurred. Among 63 patient being followed up for 1~3 years,the recurrence rate of gallbladder stones was 3.2%(2/63). No recurrence was noted in 46 patients with single gallstone. In the other seventeen patients with multiple stones, gallstone recurrence was found in 2 patients, the recurrence rate was 11.8%(2/17). Conclusions :If selection of the operation idications are strict, endoscope assisted microincision cholelithotomy for treatment of gallstone is simple, safe, effective and less trauma, and can preserves the function of gallbladder, but it can not replace the cholecystectomy.
