Transvaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) in Benign Gynaecology: A Systematic Review of Adnexal, Myomectomy and Prolapse Procedures

OBJECTIVE

Vaginal natural orifice transluminal endoscopic surgery (vNOTES) is utilised for gynecological procedures globally, however evidence to support its application aside from hysterectomy is lacking. A systematic review to determine feasibility and safety profile of vNOTES for benign gynaecology was conducted.

DATA SOURCES

A literature search of MEDLINE, EMBASE, CINAHL, SCOPUS, and CENTRAL was conducted, including all types of studies reporting vNOTES for gynecological indications. After excluding cases with concurrent hysterectomy, the review focuses on procedures for benign indications and oncological procedures are reported separately. Patient characteristics and perioperative outcomes were reported, with pooled analysis for sufficiently powered categories.

METHODS OF STUDY SELECTION

Fifty-four articles were analyzed, including 7 comparative studies (n = 439) and 1 RCT (n = 34), reporting 2469 cases of vNOTES, including adnexal (tubal and/or ovarian) (43 articles, n = 2261), myomectomy (10 articles, n = 136) and prolapse repair (6 articles, n = 72) in predominantly premenopausal women with BMI <30 kg/m2 on pooled analysis.

TABULATION, INTEGRATION AND RESULTS

The overall conversion rate was low (1.38%, n = 34) with procedure specific conversion rates of 0.45 to 6.8% for adnexal procedures, 1.47% for myomectomy and none reported for prolapse repair. Overall complication rates were low (3.44%, n = 85) with no associated mortality. Five (0.20%) adhesion-related rectal injuries at colpotomy were noted, all repaired intraoperatively without long-term sequelae.

CONCLUSION

vNOTES appears feasible based on limited evidence, for uterine-sparing gynecological indications, despite a notable rate of rectal injury at colpotomy. There is a negligible risk of rectal injury observed at conventional laparoscopy and robotically assisted surgery, but similar rate of entry-related gastrointestinal injury. This may be due to the learning-curve or suboptimal case selection, necessitating careful training, assessment, and appropriate patient selection. Surgeons should continue registering prospective vNOTES cases via iNOTESs, to evaluate emerging perioperative trends with global uptake of this novel technique.

[Prophylactic hysterectomy (Lynch syndrome, BRCA and others)]

Endometrial cancer is the 4th most common cancer in women in France, with an increasing incidence partly due to the increase in diabetes and obesity. A genetic predisposition is found in approximately 5% of cases, notably Lynch syndrome, Peutz-Jeghers syndrome, hamartomatous tumor syndrome (Cowden syndrome), and BRCA1/2 mutations. Although no organized screening is in place for endometrial cancer in the general population, individual screening is recommended for most of these at-risk populations. Prophylactic surgery is a key strategy to reduce the risk of endometrial cancer in high-risk women. For patients with Lynch syndrome, recommendations favor a total hysterectomy with bilateral salpingo-oophorectomy starting at age 40, after childbearing is complete. Hormonal supplementation with natural estrogens is important until the physiological age of menopause to reduce bone and cardiovascular risks and to improve the quality of life, including sexual health, for these women. In Cowden syndrome and Peutz-Jeghers syndrome, the lack of data limits surgical recommendations, although prophylactic hysterectomy may be considered starting at age 40, once childbearing is complete. For patients with BRCA1/2 mutations, while risk-reducing adnexal surgery is recommended, hysterectomy remains debated. It requires a personalized assessment with patients based on the benefit/risk balance.

Clinical efficacy and safety study of vNOTES for benign ovarian tumors in obese patients

To evaluate the clinical efficacy and safety of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) for treating benign ovarian tumors in obese patients. A retrospective analysis was conducted on the clinical data of 35 obese patients who underwent vNOTES for benign ovarian tumor resection and 41 obese patients who underwent multi-port laparoscopic surgery (MPLS) during the same period from January 2021 to June 2024 at Qinghai Red Cross Hospital. Key parameters such as operative time, intraoperative blood loss, intraoperative and postoperative complications, hospitalization duration, postoperative anal exhaust time, postoperative visual analog scale (VAS) score, and SF-36 score were analyzed. No statistical differences were observed between the two groups regarding baseline characteristics such as age, body mass index (BMI), tumor diameter, parity, and history of pelvic surgery. The vNOTES group exhibited shorter operative times compared to the MPLS group, with no significant differences in tumor pathology, intraoperative blood loss, or tumor rupture rates. Postoperatively, the vNOTES group had shorter hospital stays, fewer postoperative complications, lower 24-hour postoperative VAS scores, and higher three-month postoperative SF-36 scores compared to the MPLS group. No differences were found between the groups concerning anal exhaust time, sexual satisfaction rate, or 24-hour postoperative VAS scores. vNOTES is a safe and feasible surgical method for treating benign ovarian tumors in obese patients, offering advantages such as no abdominal incisions and quicker postoperative recovery.

Is transvaginal natural orifice transluminal endoscopic surgery (vNOTES) indicated in patients with previous extensive pelvic surgeries? A case report

Transvaginal natural orifice transluminal endoscopic surgery (vNOTES) has been increasingly applied to perform multiple gynecologic procedures. However, evidence is lacking on whether this surgical approach is feasible for patients with prior extensive abdominopelvic surgeries.

We report a case of prophylactic bilateral salpingo-oophorectomy (BSO) performed in a 51-year-old patient with previous laparotomic radical hysterectomy and pelvic lymphadenectomy for cervical cancer. The patient underwent rectovaginal examination and evaluation of the transvaginal sonographic sliding sign as preoperative screening to exclude the obliteration of the pouch of Douglas. The abdominal cavity was accessed by cautious endoscopic access to the pouch of Douglas. The BSO was realized in accordance with risk-reducing surgery guidelines. No intraoperative or postoperative complications were observed.

We suggest that selecting patients carefully prior to operation and adapting intraoperative techniques could be a safe method for conducting vNOTES interventions in patients with extensive abdominopelvic adhesions.
