Is this trial a fit for you?

Likely a good fit

Women aged 18–43 with symptomatic endometriosis and at least one endometrioma >20 mm who plan to try to conceive after surgery and can attend follow-up visits are ideal candidates.

Probably not a fit

Patients who are not planning pregnancy, are pregnant or breastfeeding, have cysts later found not to be endometriomas, are under legal guardianship, or cannot understand French are unlikely to benefit.

What this trial studies

This randomized interventional study will enroll women aged 18–43 with at least one endometrioma larger than 20 mm who intend to conceive after surgery. Participants are randomly assigned to one of several surgical approaches — cystectomy, plasma vaporization, or sclerotherapy — performed at Clinique Tivoli in Bordeaux. Researchers will track pregnancies (natural and with fertility treatment), births continuing beyond 12 weeks, recurrence of endometriomas, surgical complications, and changes in pain using follow-up visits at about 3 months and 24 months after the procedure. The primary outcome is pregnancy within 24 months, with secondary outcomes including birth rates, recurrence, complications, and pain scores.

Why it matters

Potential benefit: If successful, the results could identify the surgical method that best preserves ovarian function and improves the chance of pregnancy while reducing recurrence and complications.

How similar studies have gone: Previous studies have shown mixed results: cystectomy can reduce recurrence but may reduce ovarian reserve, while sclerotherapy and ablation techniques are less invasive with limited and inconsistent evidence on pregnancy outcomes.
