To evaluate the effect of 3D laparoscopic cholecystectomy combined with choledocholithotomy.

From 2016 January to 2017 October, 68 cases of cholelithiasis were selected and treated with laparoscopic cholecystectomy plus common bile duct exploration in our hospital. According to the operation method, the patients were divided into two groups: 3D laparoscopic group (3D group) and 2D laparoscopic group (2D group). Clinical data of the two groups were analyzed by SPSS20.0 software. The related indexes of operation and 3 months after operation in both groups were analyzed. The quantitative data such as the quality of Life scale (QOL) were expressed as (±s) and compared with independent t test, the incidence of postoperative complications and follow-up data were expressed in the number of cases and compared with chi square. A P<0.05 was considered as significant difference.

Compared with 2D group, the operation time and bleeding volume in 3D group were significantly reduced (P<0.05). There were no significant difference in postoperative drainage time, average hospitalization time, hospitalization cost and the incidence of postoperative complications. There was no significant difference in 3~12 months follow-up, 1 patient in 2D group with recurrence of stone was found and no residual stone in 3D group was found. 3 months after operation, the quality of life in 3D group was significantly better than that in 2D group.

The success rate of laparoscopic cholecystectomy plus common bile duct exploration was improved by 3D laparoscopic technique. It can be helpful to the accuracy of the operation, shorten the operation time, reduce the amount of intraoperative bleeding and does not increase the incidence of complications, which is worth popularizing in clinic.
