To explore the clinical effect of laparoscopic common bile duct exploration without T-tube in the treatment on common bile duct stones.

122 cases of patients with common bile duct stones treated from March 2012 to December 2018 were selected and analyzed retrospectively. All the patients were divided into free T-tube group and T-tube drainage group according to the therapeutic procedure. 62 patients were received laparoscopic common bile duct exploration without T-tube, while 60 patients were treated with laparoscopic common bile duct exploration with T-tube drainage. The SPSS 17.0 was used for statistical analysis, the operative parameters and GIQLI score were presented as (±s) and compared by t test, and postoperative complications were compared by chi square test. A P<0.05 was considered as significant difference.

In the free T-tube group, 10 cases received laparoscopictranscystic common bile duct explaration and 52 cases had laparoscopic choledocholithotomy plus primary biliary suture. The operative time, the primary exhaust time, postoperative hospital stay were lower in the free T-tube group than those in the T-tube drainage group. There was no significant difference between the two groups in the intraoperative blood, postoperative complications. The GIQLI scores in the free T-tube group were significantly higher than those in the T-tube drainage group at 2 and 4 weeks postoperatively, and there was no statistical difference at 8 weeks after operation.

Laparoscopic common bile duct exploration with free T tube is safe and feasible in the treatment of common bile duct stone. It can shorten the operative time and postoperative hospital stay, promote patients gastrointestinal function recovery, and improve patient quality of life after surgery.
