To investigate the clinical effect of laparoscopic choledocholithotomy combined with T-tube-free primary suture.

84 cases of congenital choledocholithiasis treated in our hospital from January 2015 to December 2016 were selectedand analyzed. All the patients were divided into T tube drainage group and T-tube-free primary suture group according to the therapeutic procedure. 41 patients in T tube drainage group were received laparoscopic minimally invasive lithotomy combined with T-tube drainage, while 43 patients in T-tube-free primary suture group were treated with laparoscopic minimally invasive lithotomy combined with T tube-free suture. Statistical analysis were performed by using SPSS17.0, clinical data of intraoperative and postoperative recovery and GIQLI score were presented as (±s) and compared by t test; Complications were compared by chi square test. A P value of <0.05 was considered as significant difference.

The operation time, indwelling time of drainage tube, postoperative hospital stay in T-tube-free primary suture group patients were significantly lower than those in T tube drainage group (P<0.05). The overall incidence of biliary tract hemorrhage, infection and stenosis in T-tube-free primary suture group was 2.3%, which was significantly lower than that in T tube drainage group of 14.6% (P<0.05). At 3 months after operation, the GIQLI scores of both groups were significantly higher than preoperative GIQLI scores, and the GIQLI scores of T-tube-free primary suture group was significantly higher than that of T tube drainage group (P<0.05).

Laparoscopic choledocholithotomy combined with T-tube-free primary suture has significant curative effect, shorter operative time, shorter postoperative hospital stay, shorter postoperative drainage tube indwelling time, which can promote patients Gastrointestinal function recovery, decrease the complication rates, improve patient quality of life after surgery, has higher clinical value.
