Objective: To evaluate the safety, feasibility, and key surgical techniques of laparoscopic choledochojejunostomy reconstruction for anastomotic stenosis following biliary-enteric internal drainage surgery. Methods: The clinical data of 5 patients with anastomotic stenosis after biliary-enteric internal drainage surgery, admitted to The First Affiliated Hospital of Hunan Normal University between March 2025 and August 2025, were retrospectively reviewed and analyzed. All patients provided written informed consent, and the study was conducted in compliance with medical ethics standards. There were 3 males and 2 females, with an age range of 10–45 years and a median age of 17 years. Outcome measures included operation time, intraoperative blood loss, postoperative anal exhaust time, postoperative hospital stay, and perioperative complications. Results: All 5 patients successfully underwent laparoscopic choledochojejunostomy reconstruction without conversion to open surgery. The operation time ranged from 220 to 380 minutes (median, 235 minutes), and the intraoperative blood loss was 20–80 mL (median, 50 mL), with no blood transfusion required in any case. T-tube drainage was performed in 2 patients. The postoperative anal exhaust time was 1–2 days (median, 2 days), and the postoperative hospital stay was 5–7 days (median, 6 days). No perioperative complications occurred in any patient. Conclusion: Laparoscopic choledochojejunostomy reconstruction is a safe and feasible surgical approach for anastomotic stenosis after biliary-enteric internal drainage surgery, offering advantages of minimal invasiveness and a low incidence of perioperative complications.
