Objective To investigate the clinical effect of reserving gallbladder cholecystolithotomy by using laparoscopy com-bined with choledochoscopy in the treatment of gallbladder polyp and cholecystolithiasis .Methods The clinical data of 108 patients with gallbladder polyp complicating gallstone in our hospital were retrospectively analyzed .The patients were divided into 2 groups according to the operation modes .The treatment group adopted laparoscopy combined with choledochoscopy ,while the control group was treated by the traditional laparotomy .The clinical effect ,operation time ,postoperative out-of-bed time ,length of postop-erative hospital stay and occurrence rate of postoperative complications were compared between the two groups .Results The aver-age operation time had no statistical difference between the two groups (P>0 .05) .The average postoperative out-of-bed time and the time of postoperative hospital stay in the treatment group were significantly shorter than that in the control group (P<0 .05) . The occurrence rate of postoperative complications in the control group was higher than that in the treatment group (P<0 .05) . Conclusion The application of laparoscopy combined with choledochoscopy in reserving gallbladder choledochoscopy for treating gallbladder polyp and cholecystolithiasis has obvious effect and less complications ,and is worth being popularized in clinic .
