Introduction:
Endometriosis affects 5-10% of women during reproductive years, with a 20-30% incidence among those with infertility. Deep infiltrating endometriosis (DIE) affects 10-15% of women of childbearing age and 50% of infertile women. When hormonal therapy and conservative surgery prove ineffective, total hysterectomy with or without bilateral salpingo-oophorectomy may be the ultimate therapeutic option. Laparoscopic surgery is the gold standard for treating endometriosis, offering effective disease eradication, safety, reduced pain, shorter hospital stay and faster recovery compared with laparotomy. However, patients undergoing total laparoscopic hysterectomy with DIE have higher risks of complications and organ damage, particularly urinary tract damage. Robot-assisted laparoscopic hysterectomy has emerged as a promising alternative, with a significantly lower conversion rate than total laparoscopic hysterectomy in patients with endometriosis. This study evaluates the safety and efficacy of robot-assisted total laparoscopic hysterectomy (RATLH) versus total laparoscopic hysterectomy (TLH) in the management of DIE. We hypothesise that robot-assisted laparoscopic hysterectomy will result in fewer complications and better outcomes compared with total laparoscopic hysterectomy in DIE patients.
Methods And Analysis:
The ENDORAS trial is a prospective, multicentre, open-label, randomised controlled trial conducted in French reference hospitals specialising in endometriosis surgery. A total of 224 adult women patients will be enrolled in this study if they have DIE with adenomyosis, and without digestive tract involvement as confirmed by MRI. Participants will be randomised to undergo either RATLH or TLH. The primary outcome will be the intraoperative and postoperative complication rates, classified according to the Clavien-Dindo classification (grade 2 or above) at the 3-month postoperative follow-up. Among the secondary outcomes, we will evaluate the quality of life using various questionnaires, including the Endometriosis Health Profile-30, the Short Form-306 and the Female Sexual Function Index.
Ethics And Dissemination:
The ENDORAS trial will be conducted in accordance with the International Council on Harmonization Good Clinical Practice guidelines. All trial documents and procedures have been reviewed and approved by the Ethics Committee Ile de France II (approval ID number: 24.01408.000300). Informed consent will be obtained during the preoperative check-up by the operating gynaecologist. The results will be actively disseminated through peer-reviewed journals, conference presentations, social media, broadcast media, print media and the internet.
