To evaluate the feasibility and safety of optimized laparoscopic choledocholithotomy T-tube drainage (LCHTD) in the treatment of common bile duct stones.

Retrospective analysis of clinical data from February 2018 to April 2020 for 54 patients with choledocholithiasis and gallstones who underwent optimized laparoscopic choledocholithotomy T-tube drainage.

Optimized laparoscopic choledocholithotomy T-tube drainage was completed successfully for 54 patients. The operative time was (152.4±51.2) min, the postoperative time of extraction of subhepatic drainage tube (4.3±1.4) d, the postoperative hospitalization time was (5.8±2.0) d. One patient had bile leakage after operation, with an incidence rate of 1.9%, One patient had residual stones after T-tube angiography 6-8 weeks postoperatively, with an incidence of 1.9%. Postoperative follow-up of 51 patients showed no calculus regeneration or bile stricture occurred.

Optimized laparoscopic choledocholithotomy T-tube drainage is safe and effective for the treatment of choledocholithiasis. Optimized surgical procedures and novel common bile duct suture methods can ensure efficient and high-quality completion of the operation and reduce postoperative complications.
