Abstract: Objective To explore the effectiveness of two surgical methods,primary suture of the common bile duct and T-tube drainage,in laparoscopic choledocholithotomy and choledochoscopy for stone extraction.〖WTHZ〗Method The prospectively selected 90 patients with laparoscopic lithotomy were treated from January 2019 to May 2023.They were divided into two groups.45 patients in the control group was treated with T tube drainage,and 45 patients in the observation group were treated with primary suture.Surgery-related indicators,IL-1 β level,liver function level,and postoperative complication rate were compared.The residual stone rate was compared after 3 months.Results Intraoperative blood loss,postoperative exhaust time,drainage tube removal time,postoperative complication rate and stone residual rate were not statistically different between the two groups (P>0.05).The stone removal time and hospitalization time of the observation group were shorter than those of the control group,and the total hospitalization cost was less than that of the control group,with statistical significance (P<0.05).The TBil,ALT,TBil and ALT of 1 day after surgery were all lower than those of control group,and the difference was statistically significant (P<0.05).Conclusion One-stage suture of common bile duct after laparoscopic choledochotomy and choledochoscopy can shorten the time of lithotomy,reduce the liver damage,improve the quality of life and accelerate the recovery of the disease.
