To analyze the key procedural steps and technical refinements of laparoscopic Sugarbaker repair for parastomal hernia, and to investigate the incidence of postoperative complications, aiming to further standardize the critical details of the laparoscopic Sugarbaker technique and reduce postoperative complication rates.

A single-center retrospective cohort study was conducted to analyze the clinical data of 161 patients who underwent laparoscopic Sugarbaker repair for parastomal hernia at the Department of Hernia and Obesity Surgery, The First Affiliated Hospital of University of Science and Technology of China, from January 2015 to December 2025. Data such as conversion to open surgery, postoperative complications, operative time, hernia defect size were recorded, and follow-up was completed.

All 161 surgeries were successfully completed, with 2 conversions to open surgery and no perioperative deaths. The median operative time was 135 (110, 180) minutes and the median hernia defect area was 19.6 (12.6, 28.3) cm². The median follow-up time was 24 (12, 36) months. The symptomatic recurrence rate was 5.0% (8/161), and the radiological recurrence rate was 5.6% (9/161). Kaplan-Meier survival analysis showed that, based on 10-year study data (maximum follow-up of 96 months), the 8-year cumulative symptomatic recurrence rate was 7.4% and the 8-year cumulative radiological recurrence rate was 8.1%. The overall incidence of other complications was 7.5% (12/161), including intestinal obstruction (n=3), stoma mucocutaneous separation (n=3), stoma infection (n=2), and one case each of delayed intestinal fistula from the hernia sac, hernia sac effusion, reoperation for recurrence, and poor wound healing.

Optimized key techniques in laparoscopic Sugarbaker repair demonstrate favorable outcomes for parastomal hernia, and can effectively control the incidence of postoperative complications.
