Transvaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) is a recent innovation in minimally invasive surgery which has already proven its non-inferiority to conventional abdominal laparoscopy (CAL) for hysterectomy in terms of efficiency and safety. However, the investigators note a lack of medical literature and no specific randomized controlled trial (RCT) assessing women's sexual function after vNOTES for benign adnexal surgery.
The aim of this RCT is to confirm the non-inferiority of the vNOTES approach for benign adnexal pathology compared to CAL on women's sexual function. Secondary outcomes will evaluate vNOTES's efficiency, morbidity and postoperative complications compared to CAL for benign adnexal surgery. The relationship between adnexal mass morcellation/aspiration and the quality of the histological analysis on surgical specimens will also be evaluated as secondary outcome.
This study focuses on women aged 18 to 70 who require surgery for benign adnexal disease (removal of an ovarian cyst, ovary and/or fallopian tube). This is a randomised study, i.e. each woman will be randomly assigned the surgical technique used for the planned operation, either vNOTES or conventional transabdominal laparoscopy.
Currently, there are no randomised clinical trials specifically investigating the impact on women's sexual quality of life after benign adnexal surgery compared to conventional transabdominal laparoscopy. Patients appear to be more reticent about the vaginal approach to surgery due to fear of possible alteration of their sexual activity afterwards. Indeed, their fears relate to the vaginal scarring that occurs during the vNOTES surgery. The vaginal scar could cause vaginal pain and pain during sexual intercourse, especially if there is a post-operative complication with the vaginal scar. The vaginal scar could also alter women's perception of their bodies during sexual intercourse. This study is necessary to answer these questions and increase women's acceptance of the vNOTES technique for benign adnexal surgery. In this way, women would benefit from the advantages of vNOTES without fearing an impact on their sexual quality of life.
The primary objective of this study is to demonstrate that the vNOTES technique, although using the vagina as an entry route, does not significantly alter the quality of sexual life of women after benign adnexal surgery compared to conventional transabdominal laparoscopy.
The secondary objectives of this study evaluate the effectiveness of vNOTES (impact on pain, length of stay after surgery and patient satisfaction), complications ( during surgery and up to 30 days after surgery), as well as the relationship between the need to cut the surgical specimen for extraction and the difficulty of microscopic analysis.
All participants in the study, regardless of the surgical technique assigned to them, will complete questionnaires to assess their quality of sexual life before surgery and at 3 and 6 months after surgery. These are the FSFI (female sexual function), CSI-16 (couple satisfaction) and a self-created questionnaire on pain during sex (dyspareunia). These questionnaires will determine whether there is a difference in the women's quality of sexual life before and after surgery, as well as comparing the two surgical techniques. The participants' general and medical data will be collected at the time of study enrolment, during hospitalisation and at one month after surgery to assess the secondary objectives of the study.

| Women's quality of sexual life evaluation - Female Sexual Function Index (FSFI) | Women's sexual Quality of Life evaluation after benigne adnexal surgery by vNOTES compared to Conventional Abdominal Laparoscopy using the Female Sexual Function Index (FSFI) questionnaire. FSFI, created in 2000 by Raymond Rosen, is a reliable and complete multidimensional self-reported instrument for the measurement of female sexual function. It is validated in English and assesses 19 items divided into six domains of sexual function: (a) desire (2 items), (b) subjective arousal (4 items), (c) lubrication (4 items), (d) orgasm (3 items), (e) satisfaction (3 items) and (f) pain/discomfort (3 items). Each item focuses on the situation during the last 4 weeks. The total score is the sum of answers provided for each of the 6 domains. Lower is the score, worse is the patient's sexual function. A total score below 26 defines impaired sexual function. | Preoperative |
