Single port laparoscopy (SPL): Retrospective study evaluating postoperative pain in comparison with conventional laparoscopy (CL)

Abstract

Objective: To compare postoperative pain after single port laparoscopy (SPL) approach with conventional laparoscopy (CL) in case of adnexectomy.

Material and methods: This is a retrospective monocentric study involving patients who underwent adnexal surgery by SPL or CL for a suspected benign disease or as a preventive measure. The main outcome measure was the level of postoperative pain.

Results: A total of 87 patients were enrolled. Within 2h, the numerical scale (NS) was 1.9 in SPL group and 2.0 in the CL group (P=0.85). The next day, the NS was 1.8 in SPL group and 1.5 in CL group (P=0.55). The operating time was significantly shorter in SPL group (33 versus 56min, 95% CI [-31; -15], P<0.001) and no rupture of ovarian cysts occurred in this group. There was no significant difference concerning complications, length of hospital stay, general satisfaction and POSAS (Patient and Observer Scar Assessment Scale) score.

Conclusion: This study confirms the feasibility of single-port laparoscopic adnexectomy. We have not shown significant difference in postoperative pain but the operating time was significantly reduced under the guise of an experienced surgeon.
