Objective: To demonstrate how a radical hysterectomy with sentinel node resection for cervical cancer can be performed via vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES)., Design: Demonstration of the technique in 10 steps. making use of narrated original video footage SETTING: The surgical treatment of cervical cancer is traditionally performed via one of the following techniques: Wertheim radical hysterectomy via laparotomy, Schauta radical hysterectomy vaginally, laparoscopic radical hysterectomy or robotic radical hysterectomy. The results of the LACC trial showed that minimally invasive radical hysterectomy was associated with lower rates of disease-free survival and overall survival than open radical hysterectomy among women with early-stage cervical Cancer [1]. For endometrial cancer, a vNOTES retroperitoneal approach to sentinel node resection was first published in 2019 [2]. Based on the experience with this approach and with Schauta-Stoeckel radical hysterectomy for cervical cancer [3], a new approach was developed to perform a radical hysterectomy via vNOTES whereby most of the procedure is performed retroperitoneally [4]. This video article demonstrates in 10 steps how a radical hysterectomy via vNOTES is performed., Interventions: Radical hysterectomy via vNOTES demonstrated making use of original video footage of a 57-year-old woman operated on for cervical adenocarcinoma 7 weeks after a LEEP cone. The steps of the procedure are: 1. Vaginal cuff creation, 2. Development of lateral retroperitoneal space and sentinel node resection, 3. Uterine artery and vein transection, 4. Hypogastric nerve dissection, 5. Development of central retroperitoneal space and rectum dissection, 6. Posterior colpotomy, 7. Parametrium dissection, 8. Bladder pillar dissection, 9. Anterior colpotomy, 10. Salpingo-oophorectomy or salpingectomy. 3 Patients were so far treated by this new technique that allowed for good hemostatic control., Conclusion: vNOTES enables a potentially less invasive approach to radical hysterectomy performed largely retroperitoneally and completely transvaginally, leaving no visible scars. The endoscopic approach offers excellent visualization of the retroperitoneal and parametrial anatomy. This is a new approach that requires further validation and should only be performed in a research setting, taking into account the current reservations about endoscopic surgery for cervical cancer resulting from the LACC trial.

Introduction: Hysterectomy is one of the most common major gynecological surgeries, and it is performed for benign and malignant reasons. Currently, five types of hysterectomies are described: vaginal (VH), abdominal (AH), laparoscopic (LH), robotic, and vNOTES (vaginal natural orifice transluminal endoscopic surgery). This paper compares these two types of surgery in obese patients by analyzing the surgeries performed by our team., Materials and Methods: The research was conducted from January 2022 to December 2023 at the Department of Gynecology and Obstetrics of the General Hospital in Zadar. The study included female patients aged 18-75 years with a BMI > 30 kg/m2, regardless of parity, who were operated on for benign pathology., Results: There were 24 patients included in total. One conversion was observed in the TLH group because of excessive bleeding. Median operative time (IQR) was significantly lower in the vNOTES group (p < 0.05) than in the TLH group 35 (10.9) vs 125 (74.0) min., Conclusion: The results concerning the duration of surgery, conversion rate, and postoperative bleeding and complications show that vNOTES hysterectomies seem to be feasible for obese patients. Further studies are needed to confirm these observations., (© 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Objective: To compare hysterectomy by transvaginal natural orifice transluminal endoscopic surgery (vNOTES) versus total laparoscopic hysterectomy (TLH) as a day-care procedure., Design: Parallel group, 1:1 randomised single-centre single-blinded trial, designed as a non-inferiority study with a margin of 15%., Setting: Belgian teaching hospital., Population: Women aged 18-70 years scheduled to undergo hysterectomy for benign indications., Methods: Randomisation to TLH (control group) or vNOTES (experimental group). Stratification according to uterine volume. Blinding of participants and outcome assessors., Main Outcome Measures: The primary outcome was hysterectomy by the allocated technique. We measured the proportion of women leaving within 12 hours after hysterectomy and the length of hospital stay as secondary outcomes., Results: We randomly assigned 70 women to vNOTES (n = 35) or TLH (n = 35). The primary endpoint was always reached in both groups: there were no conversions. We performed a sensitivity analysis for the primary outcome, assuming one conversion in the vNOTES group and no conversions in the TLH group: the one-sided 95% upper limit for the differences in proportions of conversion was estimated as 7.5%, which is below the predefined non-inferiority margin. More women left the hospital within 12 hours after surgery after vNOTES: 77 versus 43%, difference 34% (95% CI 13-56%), P = 0.007. The hospital stay was shorter after vNOTES: 0.8 versus 1.3 days, mean difference -0.5 days, (95% CI -0.98 to -0.02), P = 0.004., Conclusions: vNOTES is non-inferior to TLH for successfully performing hysterectomy without conversion. Compared with TLH, vNOTES may allow more women to be treated in a day-care setting., Tweetable Abstract: RCT: vNOTES is just as good as laparoscopy for successful hysterectomy without conversion but allows more day-care surgery., (© 2018 Royal College of Obstetricians and Gynaecologists.)

Objective: To critically appraise studies comparing benefits and harms in women with benign disease without prolapse undergoing hysterectomy by natural orifice transluminal endoscopic surgery (NOTES) versus laparoscopy., Study Design: We followed the PRISMA guidelines. We searched MEDLINE, EMBASE and CENTRAL for randomised controlled trials (RCTs), controlled clinical trials (CCTs) and cohort studies comparing NOTES with laparoscopy assisted vaginal hysterectomy (LAVH) or total laparoscopic hysterectomy (TLH) in women bound to undergo removal of a non-prolapsed uterus for benign disease. Two authors searched and selected studies, extracted data and assessed the risk of bias independently. Any disagreement was resolved by discussion or arbitration., Results: We did not find RCTs but retrieved two retrospective cohort studies comparing NOTES with LAVH. The study quality as assessed by the Newcastle-Ottawa scale was acceptable. Both studies reported no conversions. The operative time in women treated by NOTES was shorter compared to LAVH: the mean difference (MD) was -22.04min (95% CI -28.00min to -16.08min; 342 women; 2 studies). There were no differences for complications in women treated by NOTES compared to LAVH: the risk ratio (RR) was 0.57 (95% CI 0.17-1.91; 342 women; 2 studies). The length of stay was shorter in women treated by NOTES versus LAVH: the MD was -0.42days (95% CI -0.59days to -0.25days; 342 women; 2 studies). There were no differences for the median VAS scores at 12h between women treated by NOTES (median 2, range 0-6) or by LAVH (median 2, range 0-6) (48 women, 1 study). There were no differences in the median additional analgesic dose request in women treated by NOTES (median 0, range 0-6) or by LAVH (median 1, range 0-5) (48 women, 1 study). The hospital charges for treatment by NOTES were higher compared to LAVH: the mean difference was 137.00 € (95% CI 88.95-185.05 €; 294 women; 1 study)., Conclusions: At the present NOTES should be considered as a technique under evaluation for use in gynaecological surgery. RCTs are needed to demonstrate its effectiveness., (Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.)

Introduction: Natural orifice transluminal endoscopic surgery (NOTES) uses natural body orifices to access the cavities of the human body to perform surgery. NOTES limits the magnitude of surgical trauma and has the potential to reduce postoperative pain. This is the first randomised study in women bound to undergo hysterectomy for benign gynaecological disease comparing NOTES with classical laparoscopy., Methods and Analysis: All women aged 18-70 years, regardless of parity, consulting at our practice with an indication for hysterectomy due to benign gynaecological disease will be eligible. After stratification according to uterine size on clinical examination, participants will be randomised to be treated by laparoscopy or by transvaginal NOTES. Participants will be evaluated on day 0, days 1-7 and at 3 and 6 months. The following data will be collected: the proportion of women successfully treated by removing the uterus by the intended approach as randomised; the proportion of women admitted to the inpatient hospital; postoperative pain scores measured twice daily by the women from day 1 to 7; the total amount of analgesics used from day 1 to 7; readmission during the first 6 weeks; presence and intensity of dyspareunia and sexual well-being at baseline, 3 and 6 months (Short Sexual Functioning Scale (SSFS) scale); duration of surgery; postoperative infection or other surgical complications; direct and indirect costs incurred up to 6 weeks following surgery. The primary outcome will be the proportion of women successfully treated by the intended technique; all other outcomes are secondary., Ethics and Dissemination: The study was approved on 1 December 2015 by the Ethics Committee of the Imelda Hospital, Bonheiden, Belgium. The first patient was randomised on 17 December 2015. The last participant randomised should be treated before 30 November 2017. The results will be presented in peer-reviewed journals and at scientific meetings within 4 years after starting recruitment., Trial Registration Number: NCT02631837; Pre-results., (Published by the BMJ Publishing Group Limited.

Vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) combines the advantages of vaginal surgery with those of laparoscopic surgery. Feasibility of vNOTES for other indications such as hysterectomy, ovarian cystectomy and myomectomy has been established. In this article, we describe a standardised step by step process to perform adnexal surgery by vNOTES. [ABSTRACT FROM AUTHOR]

Study Objective: To evaluate the safety and feasibility of vaginal natural orifice transluminal endoscopic surgery (vNOTES) for benign gynaecological indications.Study Design: Prospective observational study (Canadian Task Force classification II-3) in a non-university teaching hospital. One thousand consecutive patients (2013-2018) who were eligible for vNOTES approach to benign gynaecological surgery were included.Results: Patient data and perioperative outcomes were included for analysis after the vNOTES surgical approach was standardized and made the default route of surgery. Of the 1000 vNOTES cases performed during this study period, hysterectomy (73%) was the most common followed by adnexal surgery (18%) and salpingectomy (4%). The mean age of the patient cohort was 46 yrs of age (22-83) and mean BMI, 26 kg/m2(16.5-52). There was a conversion rate of 0.4% (4 cases), 3 to conventional laparoscopy and 1 to laparotomy. The mean operating time was 42 minutes (14-250 minutes). The total complication rate was 3.9% (39) of which 1% (10) was intraoperative complications and 2.9% (29) were post-operative complications. When the hysterectomy cohort was sub analyzed, the total complication rate was 5.2% in this group (intraoperative 1.4% and post-operative 3.8%) with only a 0.4% complication rate in the non-hysterectomy sub-group. Of the complications in the hysterectomy group there were 9 cystotomies (1.2%). The mean specimen weight for all hysterectomies was 172 g (20-3361 g) with an average operating time of 46 minutes (20-250).Conclusion: The perioperative outcomes of this large vNOTES case series for benign gynaecological indications is comparable to other vNOTES procedures reported in the literature apart from the risk of cystotomy which is a hysterectomy specific risk. The outcomes are that of a single high-volume surgeon incorporating cases within his respective learning curve of the surgical technique and as such should be interpreted accordingly. Since 2015 the International NOTES Society has initiated a prospective complication database where all vNOTES surgeons are invited to register their cases. [ABSTRACT FROM AUTHOR]
