Robot-assisted nerve-sparing hysterectomy for deep endometriosis resulted in longer operative times and less blood loss compared to conventional laparoscopy, with similar hospitalization and complication rates.

This retrospective study compared robot-assisted versus conventional laparoscopic nerve-sparing modified radical hysterectomy (RA-NSmRH vs CL-NSmRH) for deep endometriosis in 68 patients (50 vs 18), assessing patient characteristics and operative and perioperative outcomes, including preservation of pelvic autonomic nerves. The groups were similar in demographics and deep endometriosis burden, and all patients achieved complete removal of deep endometriosis lesions with complete bilateral pelvic autonomic nerve preservation; however, the robotic approach had significantly longer operative time (130 ± 46 vs 98 ± 22 min) and lower estimated blood loss (35 ± 44 vs 131 ± 49 ml), with no significant differences in hospitalization days or complications (Clavien–Dindo ≥ grade III), and no postoperative self-catheterization. A key limitation is that the study is retrospective and includes unequal group sizes. This paper is centrally about endometriosis — it directly compares robotic versus conventional nerve-sparing surgery outcomes for deep endometriosis with autonomic nerve preservation.
