Official title: ENDometriosis: Evaluation of Detection and Need for ALGOlogic Care Before Surgery

Run by University Hospital, Limoges · NCT06997809 · Data updated 2026-11-12

We will test whether algologic care before endometriosis surgery can improve pain and quality of life for women who have not had relief from medical therapy.

Is this trial a fit for you?

Likely a good fit

Women aged 18 to 49 with radiologically confirmed endometriosis, significant pain-related quality of life impairment, and planned laparoscopic or robotic lesion resection who understand French and have consented to participate.

Probably not a fit

Individuals without pain-related quality of life impairment or without a clear preoperative plan for algologic care may not benefit.

What this trial studies

This interventional study explores a preoperative pathway of algologic care for women with endometriosis-related pain who are planning surgery. Eligible participants have radiologically confirmed endometriosis, impaired quality of life due to pain, and a surgical plan for lesion resection. The goal is to determine if addressing pain mechanisms such as neuropathic features before surgery can improve outcomes or reduce postoperative pain. The trial compares the care pathway timing to standard pre-surgical management within a structured enrollment window. Randomization is limited by a maximum 4-month interval between randomization and scheduled surgery.

Why it matters

Potential benefit: If successful, participants may experience better pain control and quality of life before and after surgery.

How similar studies have gone: Prior research in pain management pathways suggests potential benefits of preoperative pain-targeted care, but this exact algologic pre-surgery approach for endometriosis is relatively novel.
