Robotic‐assisted versus conventional laparoscopic management of deep endometriosis involving the sacral plexus and sciatic nerve: A comparative before and after study

Abstract

AbstractObjectiveTo compare robotic‐assisted laparoscopy (RAL) and laparoscopy (LPS) for intraoperative and postoperative outcomes, and functional results after a 6‐month follow‐up period among patients having undergone excision of deep endometriosis (DE) involving the sacral plexus (SP) and sciatic nerve (SN).MethodsA retrospective analysis of 100 patients included in our prospective database, who underwent surgical eradication of DE involving the SP and SN at our tertiary referral centre between September 2018 and June 2023. Patients were managed by LPS (n = 71) until 2021, and subsequently by RAL (n = 29).ResultsBaseline symptoms and distribution of DE lesions were comparable in the two groups. Nerve dissection, nerve shaving, and intra‐nerve dissection were performed in 55 (77.5%), 14 (19.7%), and 2 (5.6%) patients in the LPS group, respectively. Nerve dissection and nerve shaving were performed and in 24 (82.8%) and 5 (17.2%) patients in the RAL group, while no cases of intra‐nerve dissection were observed (P = 0.434). Mean operative times were 183.71 ± 85.32 min and 177.41 ± 77.19 min, respectively (P = 0.734). There were no reported cases of conversion to open surgery. Intraoperative and early postoperative complications were comparable between the two groups. At 6 months follow up, we observed a significant reduction in sciatic pain in both the LPS group (39.1% vs 15.6%, P < 0.001) and RAL group (37.5% vs 25%, P = 0.001), with no differences in terms of outcomes (P = 0.1).ConclusionBoth LPS and RAL result in significant long‐term relief of symptoms associated with SP and SN endometriosis. Although surgeons found that RAL improved the quality of excision of these specific DE localizations, our study did not reveal significant advantages in terms of its outcomes.
