To investigate the clinical value of primary closure of common bile duct of laparoscopy combined with choledochoscope in the treatment of common bile duct stones.

A retrospective analysis of 84 patients with choledocholithiasis from July 2015 to October 2017 was made. According to the different surgical methods, they were divided into group A (27 cases, received laparoscopic cholecystectomy combined with choledochoscopy and choledocholithotomy and primary suture of common bile duct) and group B (29 cases, received laparoscopic cholecystectomy combined with choledochoscopy and choledocholithotomy and T tube drainage) and group C (28 cases, received traditional open cholecystectomy and choledocholithotomy and T tube drainage). The clinical data was analyzed by SPSS 22.0 statistical software, the general data and operation-related indicators were expressed as mean-standard deviation, and examined by F test. The postoperative complications were examined by chi-square test. P<0.05 was statistically significant.

The amount of bleeding and postoperative hospitalization time in group A were significantly lower than those in group B and C, and the recovery time of gastrointestinal function in group A was significantly lower than that in group C (P<0.05). There was no significant difference in the incidence of postoperative complications in all groups (P>0.05).

It is safe and feasible for patients with cholecystolithiasis and choledocholithiasis to undergo cholecystectomy, choledocholithotomy and primary closure of common bile duct by laparoscopy combined with choledochoscope under the guidance of primary suture of common bile duct and skilled laparoscopy and choledochoscopy.
