Clash of the Titans: the first multi-center retrospective comparative study between da Vinci and Hugo™ RAS surgical systems for the treatment of deep endometriosis.

Background: The proliferation of several robotic platforms presents an opportunity to pinpoint the most suitable system for specific procedures and patient profiles. This study aims to explore differences in complications and functional outcomes among patients undergoing deep endometriosis excision with the da Vinci surgical system compared to the Hugo^™ RAS system.

Method: This is a retrospective, multicenter cohort study. Patients were categorized based on the surgical system used: the Da Vinci system and the Hugo^™ RAS system. Perioperative complications, functional outcomes (via validated questionnaire: BFLUTS, KESS, GIQLI), and pain symptoms both before and after surgery were compared between the two groups.

Results: A total of six postoperative complications were reported: four in the Da Vinci system group (20%) and two in the Hugo^™ RAS system group (12.5%). No difference in the mean operative time (p = 0.647), median estimated blood loss (p = 0.179), and hospital stay (p < 0.0001) was found between the two groups. A significant difference was reported in questionnaire score changes and dyspareunia severity in the da Vinci system arm.

Conclusions: Both robotic systems offer comparable performances in terms of intraoperative complications, although there was a higher incidence of postoperative complications in patients who underwent surgery with the Da Vinci system. Moreover, there was an improvement in dyspareunia, urinary, and gastrointestinal function in the same group.
