Brief summary

The goal of this clinical trial is to compare pregnancy rates after different surgical treatments for endometriomas in adult women who have one or more ovarian cysts (endometriomas) larger than 2 cm requiring surgery. The main questions it aims to answer are: How many women become pregnant within 24 months after surgery ? What are the birth rates and different types of pregnancies (natural, with fertility treatments, and those continuing beyond 12 weeks)? How often do the endometriomas come back after surgery? What surgery-related complications occur? How do pain levels change after treatment? Researchers will compare different surgical treatment groups to see if one approach results in better pregnancy outcomes and fewer complications. Participants will: Be randomly assigned to different surgical treatment groups Undergo surgery for their endometriomas and endometriosis Attend follow-up visits at 3 months and 24 months after the procedure Have their pregnancy outcomes, pain levels, and potential complications monitored throughout the study period

Interventions

PROCEDURECystectomy

Surgical removal of the endometrioma by gently pulling the cyst wall away from the ovarian tissue (divergent traction technique)

PROCEDUREplasma vaporization

It consists of destroying the cyst wall (vaporization) using plasma energy

PROCEDURESclerotherapy

Ethanol sclerotherapy destroys the endometriotic tissue lining the inner wall of the cyst through prolonged contact with 96% alcohol

Inclusion criteria

* Patient aged between 18 and 43 years (inclusive) * Patient diagnosed with endometriosis (by histology or imaging) and symptomatic, requiring surgery (pelvic pain and/or infertility and/or risk to an organ) * Pelvic MRI or ultrasound performed within the last year showing at least one endometrioma larger than 20 mm in diameter * Patient with an intention to conceive (probable or certain) after surgery * Patient informed and having signed the consent form * Patient covered by a social security scheme

Exclusion criteria

Design outcomes

Primary

MeasureTime frameDescription
To compare pregnancy rates observed up to 24 months after surgery for endometriosis with endometrioma treatmentFrom enrollment to 24 months after the surgeryA Pregnancy is considered if the CGH is \>1000 UI/L or a intra uterine pregnancy after 5 weeks of amenorrhea

Secondary

MeasureTime frameDescription
To compare birth rates pregnanciesFrom enrollment to 24 months after the surgery
To compare spontaneous pregnancy ratesFrom enrollment to 24 months after the surgery
To compare pregnancies achieved through assisted reproductive technology (ART)From enrollment to 24 months after the surgery
To compare pregnancies progressing beyond 12 weeks of amenorrheaFrom enrollment to 24 months after the surgery
To compare the recurrence rate of endometriomas, defined as the appearance of an endometrioma larger than 2 cm on the same ovary.From enrollment to 24 months after the surgery
To compare postoperative complication ratesDuring 3 months after the surgery
To compare pain scores using the Biberoglu and Behrman scale (Biberoglu and Behrman >4)From enrollment to 24 months after the surgeryPelvic pain will be assessed using the Biberoglu and Behrman scale, which evaluates pain in three domains: dysmenorrhea, dyspareunia, and pelvic pain on palpation. Each domain is scored from 0 (no pain) to 3 (severe pain), with a total score ranging from 0 to 9. Higher scores indicate more severe pain (i.e., a worse outcome). A score greater than 4 is considered clinically significant.
