vNOTES Hysterectomy: Can It Be Considered the Optimal Approach for Obese Patients?

What is the applicability of tubal ligation with the vaginal natural orifice transluminal endoscopic surgery technique and its value in patient comfort?

OBJECTIVE

The aim of this study was to observe the feasibility of the tubal/adnexal approach using vaginal natural orifice transluminal endoscopic surgery and compare its contribution with surgeon ergonomics and postoperative patient comfort with that of conventional laparoscopy.

METHODS

We completed this study retrospectively with 47 patients. Patients were followed at their postoperative first month. We analyzed the usability of the vaginal natural orifice transluminal endoscopic surgery method over conventional laparoscopy by comparing the demographics, surgical data, and postoperative findings collected between the two groups.

RESULTS

Patients in the conventional laparoscopy group were older (39.1±3.3 years) than those in the vaginal natural orifice transluminal endoscopic surgery patient group (p=0.005). Pain intensity 24 h after surgery was lower in the vaginal natural orifice transluminal endoscopic surgery group (p=0.003), while sexual function and dyspareunia did not differ between the two groups in the first month. Patients in the vaginal natural orifice transluminal endoscopic surgery group were more relieved about painlessness and the comfort it brought than the conventional laparoscopy group (p=0.027, χ2=12.56).

CONCLUSION

Patients subjected to the vaginal natural orifice transluminal endoscopic surgery procedure showed higher levels of satisfaction, less postoperative pain, and greater comfort than those subjected to conventional laparoscopy.

Impact of Uterine Weight and Shape on vNOTES Hysterectomy: Analysis of 238 Consecutive Cases

STUDY OBJECTIVE

To compare the perioperative outcomes of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) hysterectomies for different uterine weights and shapes.

DESIGN

Observational study.

SETTING

Swiss teaching hospital.

PATIENTS

Women who underwent vNOTES hysterectomy for benign conditions between May 2020 and July 2023 (N = 238). Patients were divided into 4 subgroups depending on uterus weight and shape. Uteri weighting <280 g were classified as type 0. Uteri weighting ≥280 g were categorized as type 1 (no vascular pedicle displacement), type 2 (cranial displacement of adnexal vascular pedicles), and type 3 (displacement of uterine arteries).

INTERVENTIONS

All women underwent vNOTES hysterectomies. We compared perioperative outcomes for the 4 subgroups.

MEASUREMENT AND MAIN RESULTS

We classified 168 patients (70.6%) as uterus type 0, 33 patients (13.9%) as type 1, 24 patients (10.1%) as type 2, and 13 patients (5.4%) as type 3. Mean uterine weight was 135.8 ± 59.5 g in type 0, 398.0 ± 167.3 g in type 1, 603.5 ± 217.9 g in type 2, and 661.7 ± 281.6 g in type 3. Operative time in type 0 (65.1 ± 30.9 minutes) and type 1 (65.1 ± 24.0 minutes) was shorter than in type 2 (102.3 ± 60.0 minutes) and type 3 (115.2 ± 40.3 minutes). Blood losses were more significant in type 2 (158.5 ± 212.0 mL) and type 3 (158.5 ± 110.7 mL) than in type 0 (85.6 ± 113.5 mL). No difference in the rate of total complications among groups was observed (8.3%, 3.0%, 12.5%, and 15.4% in types 0, 1, 2, and 3, respectively).

CONCLUSION

The displacement of the vascular pedicles seems associated with longer operative time and more blood loss and could represent a marker for technical difficulty in vNOTES hysterectomy. However, it does not influence the perioperative complication rate.

Transvaginal natural orifice endoscopic surgery for ovarian cystectomy: a more suitable surgical approach for the day-care procedure

Introduction

Although previous studies have shown that vaginal natural orifice transluminal endoscopic surgery (vNOTES) has the advantages of causing less pain, faster recovery, and better concealment of surgical incisions, which aligns with the concept of the day-care procedure, this approach poses a greater risk of damaging adjacent organs (i. e., rectum and bladder) due to its anatomical specificity. Moreover, the day-care procedure may lead to relatively less preoperative evaluation and postoperative care. Hence, it is necessary to explore the safety and effectiveness of vNOTES for ovarian cystectomy in the day-care procedure, to provide a theoretical basis for the wider development of vNOTES surgery.

Materials and methods

This retrospective study included 131 patients at our hospital who underwent ovarian cystectomy from September 2021 to October 2022. Based on the surgical approach, patients were classified into transumbilical laparoendoscopic single-site surgery (LESS) and vNOTES groups. The patients' demographic characteristics and follow-up data were collected during the perioperative period and 1-month postoperatively.

Results

Vaginal natural orifice transluminal endoscopic surgery has less postoperative exhaust time, a lower postoperative 6-hour pain score, and a lower incidence of analgesic drug use, with higher surgical conversion incidence. Multiple linear regression analysis showed that the surgical conversion, chocolate cyst, bilateral cyst, and pelvic adhesion increased the operation duration by ~43 (95% CI: 10.309, 68.152, p < 0.001), 15 (95% CI: 6.342, 45.961, p = 0.036), 10 (95% CI: 3.07, 40.166, p = 0.019), and 8 (95% CI: 4.555, 26.779, p = 0.035) min, respectively. Interestingly, vNOTES decreased the operation duration by ~8.5 min (95% CI: -18.313, -2.699, p = 0.033).

Conclusion

Vaginal natural orifice transluminal endoscopic surgery was equally safe and effective for ovarian cystectomy compared to LESS. vNOTES aligned with the concept of the day-care procedure due to its reduced postoperative pain, shorter exhaust time, and absence of scarring. However, surgeons should conduct a comprehensive preoperative evaluation and exclude patients suspected to have severe pelvic adhesions.

Hysterectomy Using Vaginal Natural Orifice Transluminal Endoscopic Surgery Compared with Classic Laparoscopic Hysterectomy: A New Advantageous Approach? A Systematic Review on Surgical Outcomes

INTRODUCTION

Minimally invasive surgery aims to reduce surgical trauma and post-operative morbidity. Natural orifice transluminal endoscopic surgery is a safe and valid surgical option for hysterectomy. The present systematic review aims to compare hysterectomy by transvaginal natural orifice transluminal endoscopic surgery (vNOTES) with laparoscopic hysterectomy in terms of efficacy, surgical outcomes, complications, and cost.

MATERIALS AND METHODS

This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. It includes randomized controlled trials, controlled clinical trials, prospective or retrospective cohorts, case-control studies, and previous systematic reviews. Inclusion criteria are as follows: female patients undergoing hysterectomy for benign pathologies by vNOTES or laparoscopic hysterectomy. The assessed outcomes were the following: conversion rate, mean uterus weight (g), operative time (mins), hospital stay (days), peri-operative complications, post-operative complications, peri-operative blood loss (mL), blood transfusion needs, post-operative day 1 hemoglobin (Hb) change (g/dL), post-operative pain level (VAS), and cost (USD) in both techniques.

RESULTS

Seven studies were included. vNOTES hysterectomy was not inferior to laparoscopic hysterectomy regarding surgical outcomes, with a shorter operative time, shorter recovery time, less post-operative pain, and fewer post-operative complications. There was no significant difference in the rate of peri-operative complications and no differences in peri-operative blood loss, post-operative day 1 Hb change, and transfusions. Nevertheless, vNOTES hysterectomy was shown to be more expensive than its laparoscopic counterpart.

CONCLUSIONS

While the feasibility and safety of the vNOTES hysterectomy were already established, this review also underlines the noninferiority of this technique when compared to laparoscopic hysterectomy in terms of surgical outcomes. In addition, vNOTES hysterectomy was associated with faster operating time, shorter hospital stay, and better post-operative pain scores compared with laparoscopic hysterectomy.

The Future in Standards of Care for Gynecologic Laparoscopic Surgery to Improve Training and Education

Standards of care offer doctors and patients the confidence that an established quality, evidence-based, care is provided, and represent a tool for optimal responding to the population’s needs. It is expected that they will increasingly express a multimodal relationship with gynecologic laparoscopy. Laparoscopy is, now, a standard procedure in operative gynecology, standards are embedded in many laparoscopic procedures, standardization of the skills/competency assessment has been progressively developed, and the proof of competency in laparoscopy may become a standard of care. A continuous development of surgical education includes standard equipment (that may bring value for future advance), standardized training, testing (and performance) assessment, educational process and outcome monitoring/evaluation, patients’ care, and protection, etc. Standards of care and training have a reciprocally sustaining relationship, as training is an essential component of standards of care while care is provided at higher standards after a structured training and as credentialing/certification reunites the two. It is envisaged that through development and implementation, the European wide standards of care in laparoscopic surgery (in close harmonization with personalized medicine) would lead to effective delivery of better clinical services and provide excellent training and education.

Long-term satisfaction of patients after laparoscopic and robotic-assisted hysterectomy

Introduction

Da-Vinci-Xi is the most recent device used in gynecologic robotic surgery. The aim of the present study was to compare the long-term satisfaction of patients who had undergone conventional laparoscopic hysterectomy or robotic assisted laparoscopic hysterectomy using the Da-Vinci-Xi surgical system.

Methods

All hysterectomies performed at the University Hospital of Luebeck from 2018 to 2019 were reviewed. Postoperative outcomes were compared between women who had undergone total hysterectomy with da Vinci Xi (n = 42) or conventional laparoscopy (n = 97). Postoperative outcomes included pain, elimination of complaints after surgery, bladder function, sexual function, satisfaction with the cosmetic outcome, positive experiences after robotic surgery, and satisfaction with the surgeon’s preoperative explanation. Obese patients were evaluated separately in a subgroup analysis.

Results

Both groups had similar baseline characteristics and complication rates. Preoperative complaints subsided after surgery in a little more than 90% of patients. No significant differences were noted between groups in this regard (p = 0.262), or with reference to postoperative pain after one week (p = 0.866) and one month (p = 0.580), stress incontinence (p = 0.343), sexual function (p = 0.766) and the cosmetic outcome of the abdominal incisions (p = 0.273). The majority of patients who had undergone robotic surgery (96.8%) would be willing to undergo the procedure again if necessary. The subgroup analysis of obese patients revealed no significant differences.

Conclusion

The Da-Vinci-Xi device did not improve the long-term surgical satisfaction of normal-weight or obese patients who underwent hysterectomy compared with patients who underwent conventional laparoscopy performed by experienced laparoscopic surgeons.

The Comparison of Transvaginal Natural Orifice Transluminal Endoscopic Surgery and Conventional Laparoscopy in Opportunistic Bilateral Salpingectomy for Permanent Female Sterilization

STUDY OBJECTIVE

To compare the transvaginal natural orifice transluminal endoscopic surgery (vNOTES) approach with conventional laparoscopy (CL) in opportunistic bilateral salpingectomy (BS) alone for permanent female sterilization as an opportunistic cancer prevention strategy.

DESIGN

Prospective cohort study.

SETTING

Two-centered tertiary hospitals.

PATIENTS

Ninety-six women with a nonprolapsed uterus seeking definitive surgical permanent contraception.

INTERVENTIONS

Patients were scheduled for BS and assigned to a study arm in a 2:1 fashion (CL:vNOTES allocation ratio) concerning patient's choice.

MEASUREMENTS AND MAIN RESULTS

Patients were followed at their postoperative first week and first month. The visual analog score (VAS), Patient Global Impression of Improvement, and Female Sexual Function Index scales were used to assess the pain, patient satisfaction, and discomfort/pain after vaginal penetration, respectively. Patients who underwent to vNOTES had a significantly higher number of previous abdominal surgery (median difference, 1.97; 95% confidence interval [CI], 1.12-3.48; p = .016). Compared with CL, vNOTES was associated with lower 6-hour (rate ratio [RR], 0.63; 95% CI, 0.50-0.77) and 24-hour (RR, 0.33; 95% CI, 0.23-0.46) postoperative VAS scores and less amount of postoperative analgesics (RR, 0.54; 95% CI, 0.36-0.78). The slope of change in postoperative VAS scores was in a shorter time in the vNOTES group (RR, 0.47; 95% CI, 0.36-0.60). The rate of postoperative improvement was higher in the vNOTES group than the CL group at the postoperative first week (87.5% vs 68.2%, χ² = 4.232, p = .032) and first month (96.9% vs 87.9%, χ² = 2.091, p = .140). The rate of patients reporting postoperative decline in Female Sexual Function Index /pain scores (RR, 0.97; 95% CI, 0.47-1.96) was found to be similar in both of the study groups, and no postoperative complication was observed in either group.

CONCLUSION

Women seeking permanent sterilization and who underwent BS for ovarian cancer risk reduction purposes had higher satisfaction, less postoperative pain, lower analgesic requirement, and similar surgical outcomes in the vNOTES group than the CL group, even in patients with previous surgeries and a nonprolapsed uterus. vNOTES approach could be the preferred method for the opportunistic BS in female sterilization.
