Abstract:Abstract: Objective?To investigate the clinical effect of laparoscopic primary suture of common bile duct and retention of T-tube in treatment of aged patients with choledocholithiasis.?Methods?Clinical data of 106 elderly patients with laparoscopic common bile duct exploration from January 2013 to January 2018 were analyzed retrospectively. According to the operation mode, they were divided into two groups: primary suture group and T-tube drainage group. The suture time of common bile duct, intraoperative bleeding volume, postoperative anal exhaust time, postoperative pain score, postoperative CRP level, postoperative complications and drainage tube removal time, length of hospital-stay, cost of hospitalization, residual recurrence of stone and so on were compared between the two groups.?Results?All the operations were performed under laparoscope. In the primary suture group, the suture time of bile duct, anal exhaust time, postoperative pain score, hospitalization time, hospitalization cost [(13.6?±?3.6) vs (21.5?±?11.8) min, (1.6?±?0.6) vs (2.1?±?0.7) d, (1.4?±?0.2) vs (3.2?±?0.8), (7.3?±?2.1) vs (9.6?±?3.5)?d, (21?564.7?±?4?962.5) vs (25?376.6?±?6?537.1) yuan] were better than those in the T tube group (P?0.05). There was no significant difference in other perioperative indexes, biliary complications and stone residual recurrence between the two groups (P?>?0.05).?Conclusion?Laparoscopic primary suture of choledocholithiasis in elderly patients with choledocholithiasis has some advantages over T-tube indwelling. It is worth popularizing in basic hospitals.
