Key Points

This study evaluates the efficacy and safety of single-port laparoscopic surgery versus multi-port laparoscopic surgery for benign ovarian cysts.
Conducted a retrospective cohort study with 260 patients from January 2022 to September 2025.
Divided patients into single-port (transumbilical) and multi-port groups.
Measured perioperative indicators, inflammatory markers, hospitalization costs, and satisfaction.
Used propensity score matching to reduce bias in outcomes.
Single-port group had significantly lower 24-hour VAS scores and higher abdominal wall satisfaction.
Reduced time to first flatus, ambulation, and shorter hospital stay was observed in the single-port group.
Lower costs and inflammatory markers were noted with single-port surgery.
No significant differences in operative duration, blood loss, and AMH levels between groups.

Abstract

Objective This study aimed to evaluate the efficacy, safety, and patient-centered outcomes of single-port laparoscopic surgery (LESS) versus traditional multi-port laparoscopic surgery for benign ovarian cysts. Methods A retrospective cohort study enrolled 260 patients (January 2022–September 2025) divided into single-port group ( n = 130, transumbilical LESS) and multi-port group ( n = 130, conventional laparoscopy). Outcomes included perioperative indicators (operative duration, blood loss, time to first flatus/ambulation, hospital stay, 24-hour Visual Analogue Scale (VAS) pain), postoperative day-1 inflammatory markers (C-reactive protein (CRP), IL-6, procalcitonin), preoperative/1-3 month postoperative anti-Mullerian hormone (AMH) (ovarian reserve), hospitalization costs, and abdominal wall appearance satisfaction (POSAS). Propensity score matching (PSM) was used to reduce bias. Results After PSM, the single-port group had lower 24-hour VAS scores (2.36 ± 0.86 vs. 3.72 ± 1.30, P 0.05). No conversions, 30-day readmissions, or complication rate differences were observed ( P > 0.999). Conclusion LESS for benign ovarian cysts has comparable safety/efficacy to multi-port laparoscopy, with advantages of less pain, milder inflammation, faster recovery, lower costs, and better cosmetic satisfaction, while preserving ovarian reserve—making it a valuable minimally invasive option.
