Robotic Surgery for Severe Endometriosis: A Preliminary Comparative Study of Cost Estimation.

STUDY

OBJECTIVE

To compare the postoperative outcomes and the overall expenses between conventional laparoscopy and robotic surgery, in a series of consecutive patients managed for only severe endometriosis in our institute.

DESIGN

A cohort comparative study.

SETTING

Center of Excellence in Multidisciplinary Endometriosis Care.

PATIENTS: A total of 175 symptomatic patients undergoing surgery for only severe endometriosis from March 2021 to August 2022.

INTERVENTIONS: We treated patients with endometriosis involving the digestive tract such as rectum, sigmoid colon, and ileocecal junction by rectal shaving, discoid resection, or segmental resection (141 surgeries) with or without bladder (23 surgeries), sacral plexus (19 surgeries), and diaphragm involvements (14 surgeries).

MEASUREMENTS AND MAIN

RESULTS

Postoperative outcomes were evaluated in terms of total surgical time (total surgical room occupancy time and total operating time), hospitalization period, postoperative complications, rehospitalization, and second surgical procedures. A statistically higher total surgical room occupancy (203 minutes vs 151 minutes) and operating time (150 minutes vs 105 minutes) were observed in the robotic group (p = .001). No differences in terms of mean hospital stay (p = .06), postoperative complications (p = .91), rehospitalization (p = .48), and secondary surgical treatment (p = .78) were identified. Concerning the cost analysis only for disposable supply, the cost of colorectal resection was totaled at 2604 euros for the laparoscopic conventional approach vs 2957 euros for the robotic approach (+352.6 euros, +14%). The cost of rectal disc excision was 1527 euros for the laparoscopic conventional approach vs 1905.85 euros (+378 euros, +25%).

CONCLUSIONS

Our study confirms the feasibility of the robotic approach for the treatment of severe endometriosis, with however a higher cost of robotic approach. Next studies should identify specific indications for robotic surgery, where technical advantages provided by the technology are followed by objective improvement of patients' outcomes.
