Assessing the role of robotic surgery versus laparoscopic surgery in patients with a diagnosis of endometriosis: A meta-analysis

Abstract

Background: Surgical management of endometriosis can be carried out with the traditional standard laparoscopic technique or the robotic surgery technique; however, it is not clear if there is a significant difference between techniques. This meta-analysis aims to evaluate and compare the impact of robotic and standard laparoscopic techniques in endometriosis regarding the clinical outcome. Methods: Studies comparing robotic surgery to laparoscopic surgery for endometriosis were among the studies from various languages that met the inclusion criteria. Using dichotomous and continuous random-effect models, the results of these investigations (surgery time, hospitalization time, blood loss, complications, and conversion rate) were examined, and the mean difference with 95% confidence intervals was computed. Results: Eight studies from 2013 to 2022 were selected for the current analysis including 1741 patients with endometriosis. The studied data revealed a statistically significant (P = .01) lower operation time related to laparoscopic surgery compared with the robotic technique. In addition, the hospitalization time of laparoscopic surgery is significantly (P = .03) lower than that of robotic surgery. On the other hand, blood loss, rehospitalization, postoperative and intraoperative complications, and conversion rates were not significantly different between both techniques. Heterogeneity values were variable according to the analysis factor, from 0% to 91%. Conclusion: Both robotic and standard laparoscopic techniques have similar outcomes regarding blood loss, rehospitalization, conversion rate, and rate of complication. However, the substantial difference between techniques was in favor of standard laparoscopic surgery regarding operation and hospitalization time.
