Laparoscopic single site versus conventional laparoscopic surgery for benign ovarian masses

Aim: To explore the clinical application of laparoendosopic single-site surgery (LESS) in the treatment of benign ovarian masses of different sizes. Methods: We reviewed 117 patients with benign ovarian mass. 57 underwent LESS with self-made approach, and 60 underwent conventional laparoscopic surgery (CLS). Results: For the group with the maximum diameter of mass < 10 cm, the average operation time was 65.29 +/- 8.76 min in the LESS group, which was longer than 50.12 +/- 8.73 min in the CLS group (P < 0.001). For the other group with the maximum diameter of mass >= 10 cm, the operation time in the LESS group was 59.32 +/- 10.15 min, shorter than that in the CLS group (71.30 +/- 10.52 min) (P < 0.001), and incision aesthetic score was better in the LESS group than in the CLS group. There were no significant differences between the LESS and CLS groups in terms of intraoperative bleeding, postoperative ventilation time, postoperative ambulation time, postoperative pain score, surgical satisfaction score and postoperative length of stay (P > 0.05). Conclusion: LESS is feasible in the surgery of benign ovarian mass. Especially, it can fully demonstrate the ad-vantages of LESS in large benign ovarian mass (maximum diameter of >= 10 cm).

Automated summary

This study explores the clinical application of laparoendosopic single-site surgery (LESS) in the treatment of benign ovarian masses. The results show that LESS surgery has advantages in treating larger benign ovarian masses, with shorter operation time and better incision aesthetic score.
