総胆管結石症に対する腹腔鏡下胆道総胆管切開術とTチューブドレナージの比較：有効性と安全性に関する分析

Laparoscopic common bile duct exploration (LCBDE) is an important surgical treatment for choledocholithiasis; however, the choice between indwelling T-tube placement and primary suture remains controversial. This study aimed to evaluate the safety and feasibility of LCBDE coupled with primary suture using a prospective cohort design, as well as to summarize the key techniques of primary suturing.

Patients with choledocholithiasis who met the inclusion criteria between January 2019 and March 2023 were enrolled. The primary suture group comprised patients who underwent LCBDE with primary closure, while the T-tube drainage group consisted of those who received LCBDE with T-tube drainage. Perioperative data and follow-up outcomes were collected and statistically analyzed for both groups.

Operative time (120.00 [100.00-139.50] vs. 99.00 [85.00-118.50] min; P = 0.000) and postoperative hospital stay (7.00 [5.00-9.00] vs. 5.00 [4.00-6.00] days; P = 0.000) differed significantly between groups. No significant differences were observed in estimated blood loss (40.7 ± 24.1 vs. 41.4 ± 23.7 mL; P = 0.537), conversion rate to laparotomy (2.38% vs. 2.27%; P = 0.918), time to gastrointestinal function recovery (2.1 ± 0.7 vs. 2.0 ± 0.6 days; P = 0.317), or postoperative complication rate (2.92% vs. 3.18%; P = 0.959). During follow-up, one case of common bile duct (CBD) stenosis and one case of extrahepatic cholangiocarcinoma occurred in the T-tube group; no such complications were observed in the primary suture group. The rates of residual stones (1.75% vs. 0.45%; P = 0.225) and recurrent stones (1.75% vs. 1.81%; P = 0.980) were without statistical significance.

In our grouping situation, LCBDE and primary suture is safer and more feasible than T-tube drainage in operative time and postoperative hospital stay. This conclusion has certain reference value for clinicians to choose the surgical method in laparoscopic surgery for choledocholithiasis.
