A comparative study on effect of common bile duct primary suture and T tube drainage in laparoscopic and open cholecystectomy and common bile duct exploration

Abstract

Objective To compare the effect of common bile duct primary suture and T tube drainage in laparoscopic and open cholecystectomy and common bile duct exploration. Methods A total of 124 patients with choledocholithiasis were selected as the subjects. All patients underwent cholecystectomy+ common bile duct exploration. According to the order of hospitalization, patients were randomly divided into laparoscopic cholecystectomy+ common bile duct+ nasobiliary drainage and primary suture group (ventral suture group), open cholecystectomy+ common bile duct+ nasobiliary drainage and primary suture group (open suture group), open cholecystectomy+ T tube drainage group (open drainage group) and laparoscopic cholecystectomy+ T tube drainage group (ventral drainage group), with 31 cases in each group. The recovery time of gastrointestinal function, bile drainage volume, extubation time, hospital stay, rate of bile leakage and number of discharged patients with tube were compared among the four groups. Results The recovery time of gastrointestinal function, bile drainage volume, extubation time and hospital stay in ventral suture group were significantly lower than those in the other 3 groups (P 0.05). However, the ratios of discharged patients with tube in open suture group and ventral suture group were significantly lower than those in open drainage group and ventral drainage group (P<0.05). Conclusions Compared with the T tube drainage, common bile duct primary suture has better effect whether in the laparotomy or in the abdominal operation, and is worthy of clinical application.
