Objective: Vaginal hysterectomy combined with uterosacral suspension (USLS) is a technique for treating pelvic organ prolapse. Vaginal natural orifice transluminal endoscopic surgery (vNOTES) has been described as an alternative minimal invasive approachfor treating various gynecological and non-gynecological pathologies. The aim was to compare the surgical time between conventional vaginal hysterectomy combined with USLS and vNOTES hysterectomy combined with USLS., Study Design: Multi-center randomized controlled trial performed 2019-2021 at Rambam Health Care Campus (Israel) and Imelda Hospital (Belgium). Thirty women underwent vNOTES procedures and 30 women underwent conventional vaginal procedures. The primary outcome was total surgical time. Secondary outcomes included hysterectomy time, USLS time, intraoperative bleeding, length of hospitalization, pain during the first 24 h postoperative, the need of analgesia, intraoperative and postoperative adverse events, and patient-reported outcomes questionnaires. Parametric statistical methods were used to analyze the data., Results: Compared to conventional vaginal procedures, vNOTES procedures were shorter in total surgical time (77 vs. 93 min, p = 0.004), hysterectomy time (26 vs 33 min, p < 0.001), and USLS time (20 vs 26 min. p = 0.02). Blood loss was higher in conventional vaginal compared to vNOTES surgery, as reflected by the mean blood loss estimate (143 vs 60 ml. p < 0.001) and the delta-hemoglobin (pre-operation minus the post-operation hemoglobin level (1.8 vs 1.2 ml/dL, p = 0.01). There was no difference between the groups regarding analgesics used, postoperative pain, surgical objective outcomes, and scores on patient-reported outcomes questionnaires. Adverse events were significantly more frequent in the conventional vaginal group than in the vNOTES group (p < 0.001 for intraoperative events and p = 0.05 for events that occurred in the follow-up time interval)., Conclusion: vNOTES hysterectomy with USLS has lower surgical times than conventional vaginal hysterectomy with USLS, lower blood loss and less adverse events. Other surgical objective and subjective outcomes were similar between the approaches., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

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., (Crown Copyright © 2022. Published by Elsevier B.V. All rights reserved.)

Study Objective: The first ever report of vaginal natural orifice transluminal endoscopic surgery (vNOTES) for benign gynaecological was reported in 2012. There has been an exponential uptake of the number of surgeons performing such procedures worldwide with no official guidance to ensure the safe implementation of this technique into gynaecological practice due its recency. The objective of this study is to report an international consensus-based statement to help guide a basis for adopting vNOTES into clinical practice., Study Design: The consensus-based statement was developed amongst 39 international experts using the Delphi methodology over three successive rounds. Consensus was pre-defined as an agreement of 80% or more by the experts. Consensus sought over eight key concepts pertaining to vNOTES including patient selection, perioperative management, surgical technique, instruments, anatomy, training, registries and trials and definition of the surgical technique. Recommendations from an expert anaesthetist and urogynaecologist were also sought to give a broader perspective with respect to the implementation of vNOTES., Results: Fifty nine international surgeons were invited to participate and 39 (66%) agreed to participate based on being involved in a minimum of 20 vNOTES procedures. They were from 13 countries across 5 continents (Europe, North America, South America, Australia and Asia). Participation was 100% on all three rounds. Overall, consensus was reached in 50 of the 56 questions (89%) with the remaining 6 questions where consensus was not reached pertaining to the domain of patient selection., Conclusion: An international expert based vNOTES statement is presented here to help guide adoption of vNOTES based on the experience of early adopters. Consensus was achieved on most components of this consensus statement. Given the recency of this technique, until high-level evidence becomes available, this statement provides an appropriate guidance to the safe implementation of vNOTES into gynaecological practice., Competing Interests: Declaration of Competing Interest The authors declare that they have no conflicts of interest.

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/m 2 (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., Competing Interests: Declaration of Competing Interest The authors report no declarations of interest., (Copyright © 2020.

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.)
