Objective: This study aimed to compare the perioperative outcomes of patients who underwent hysterectomy for benign gynecologic diseases using transvaginal natural orifice transluminal endoscopic surgery (vNOTES) or transumbilical laparoendoscopic single-site surgery (TU-LESS)., Methods: A total of 314 patients who underwent hysterectomy for benign uterine disease at West China Second University Hospital between October 2018 and December 2021 were enrolled in this retrospective study. vNOTES (n = 157) and TU-LESS (n = 157) recipients were matched 1:1 in terms of uterine volume. The operation time, blood loss, postoperative decrease in hemoglobin, uterus weight, postoperative hospital stay, postoperative pain score at 12 h, postoperative indwelling catheter time, and other clinical indicators were compared between the two groups., Results: All 314 patients successfully completed the surgery, and the two groups had similar baseline characteristics, with no statistical difference. Regarding intraoperative outcomes, the operation time was shorter in the vNOTES group than in the TU-LESS group (80 vs 100 min, P = 0.04), and there were no significant differences in intraoperative blood loss, intraoperative blood transfusion rate, postoperative decrease in hemoglobin, or uterine weight. Concerning postoperative outcomes, vNOTES hysterectomy was significantly superior to TU-LESS hysterectomy in terms of the length of hospital stay (3 vs 4 days, P < 0.001), visual analog scale score for pain at 12 h after surgery (P = 0.04), postoperative indwelling catheter time (39.5 vs 64.0 h, P < 0.001), and postoperative exhaust time (24.0 vs 42.0 h, P < 0.001). There were no significant differences in postoperative complications between the two groups., Conclusion: vNOTES and TU-LESS seem safe and feasible for hysterectomy, but vNOTES hysterectomy was more conducive to the postoperative rehabilitation of patients, with less trauma, less pain, and better cosmetic effects than TU-LESS hysterectomy. As an emerging surgical approach, more studies, including large-sample, multicenter, randomized controlled trials, are needed to validate our findings., (© 2023 The Authors.

Introduction: The study aimed to compare the short-term outcomes of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) for uterosacral ligament suspension (USLS) versus nonendoscopic USLS in patients with subtotal uterine prolapse who had a concomitant vaginal hysterectomy., Methods: There were 51 patients who underwent vNOTES USLS, whereas the nonendoscopic conventional USLS group had 49 patients. The information about patient demographics, and perioperative data including the operative duration, blood loss, intraoperative and postoperative complications, and length of postoperative hospital stay were determined from the patients' files. Postoperative follow-up visits were scheduled at the first week and 1 month after surgery., Results: The demographic variables including age, body mass index, menopausal status, and parity were comparable, and no significant differences were found. A total of 90.2% of the patients in the vNOTES group and 69.4% of the patients in the shull group were at menopause (p = .09). Operation time was significantly shorter in the shull group (p < .001), and the hospitalization period (p = .029) was significantly shorter in the vNOTES group. Ba, Bp, and D points and total vaginal length (TVL) were significantly behind the hymenal ring in patients who had vNOTES USLS procedure (p < .001). None of the patients who had intraoperative significant blood loss required transfusion. One patient in the vNOTES and two patients in the shull group had a postoperative cuff hematoma., Conclusion: vNOTES USLS has a good safety profile, higher percentage of adnexal surgeries with better improvement on POP-Q points Ba, Bp, D, and TVL compared with classic USLS in patients with subtotal uterine prolapse. Studies evaluating short- and long-term results of vNOTES versus conventional USLS are needed., (© 2024 Asia Endosurgery Task Force and Japan Society of Endoscopic Surgery and John Wiley & Sons Australia, Ltd.)

Background: There is a scarcity of prospective clinical research evidence regarding the utilization of transvaginal natural orifice translumenal endoscopic surgery (vNOTES) as a treatment option for ovarian cysts. The objective of this study was to assess the feasibility and safety of employing vNOTES for the management of ovarian cysts., Methods: Our study included women between the ages of 18 and 70 who intended to undergo surgical intervention for benign lesions. Stratified blocked randomization was employed to allocate participants into groups. The main objective was to assess whether the assigned group adhered to the recommended surgical technique for ovarian cystectomy or adnexectomy, without any deviation to alternative surgical methods., Results: A total of 196 patients were included in the study, with all surgeries in each group being conducted according to the assigned procedures. Among them, the ovarian cystectomy layer included 58 cases in the vNOTES group and 58 cases in the conventional laparoscopy (CL) groups. The adnexectomy layer included 40 cases in the vNOTES group and 40 cases in the CL group. Utilizing a sensitivity analysis, the two-sided 95% lower confidence limit was determined to be 5.5% for the disparity in proportions between the vNOTES groups and CL groups. These lower limits fell below the predetermined non-inferiority margin of 10%., Conclusions: The study findings demonstrate that vNOTES was not inferior to CL in terms of adnexectomy or ovarian cystectomy. vNOTES can be considered a more minimally invasive surgical approach, as it results in reduced postoperative pain, faster recovery, and absence of visible incisions. Overall, vNOTES proves to be a safe, feasible, and less invasive treatment option., Trial Registration: This study retrospectively registered with the China Clinical Trial Registry with the registration number ChiCTR2100052223(22-10-2021)., (© 2024.

Background: Natural orifice transluminal endoscopic surgery (NOTES) is an achievement in the field of minimally invasive surgery. However, the vantage point of vaginal natural orifice transluminal endoscopic surgery (vNOTES) in gynecologicalprocedures remains unclear. The main purpose of this study was to compare vNOTES with laparo-endoscopic single-site surgery, and to determine which procedure is more suitable for ambulatory surgery in gynecologic procedures., Methods: This retrospective observational study was conducted at the Department of Gynecology, Chengdu Women's and Children's Central Hospital. The 207 enrolled patients had accepted vNOTES and laparo-endoscopic single-site surgery in gynecology procedures from February 2021 to March 2022. Surgically relevant information regarding patients who underwent ambulatory surgery was collected, and 64 females underwent vNOTES., Results: Multiple outcomes were analyzed in 207 patients. The Wilcoxon Rank-Sum test showed that there were statistically significant differences between the vNOTES and laparo-endoscopic single-site surgery groups in terms of postoperative pain score (0 vs. 1 scores, p = 0.026), duration of anesthesia (90 vs. 101 min, p = 0.025), surgery time (65 vs. 80 min, p = 0.015), estimated blood loss (20 vs. 40 mL, p < 0.001), and intestinal exhaustion time (12.20 vs. 17.14 h, p < 0.001). Treatment with vNOTES resulted in convenience, both with respect to time savings and hemorrhage volume in surgery and with respect to the quality of the prognosis., Conclusion: These comprehensive data reveal the capacity of vNOTES to increase surgical efficiency. vNOTES in gynecological procedures may demonstrate sufficient feasibility and provide a new medical strategy compared with laparo-endoscopic single-site surgery for ambulatory surgery in gynecological procedures., (© 2024.

Study Objective: To show feasibility and short-term outcomes of robot-assisted vaginal NOTES (RvNOTES) for the treatment of stage IV endometriosis during total hysterectomy with/without complete cul-de-sac obliteration., Design: Retrospective case series., Setting: Single academic tertiary care hospital in Houston, Texas, USA., Patients: Twenty-three adult women with stage IV endometriosis., Interventions: RvNOTES with total hysterectomy for excision of severe endometriosis., Measurements and Main Results: Patients were assessed for various metrics including total operative time, robot dock time, robot console time, hysterectomy time, estimated blood loss, perioperative pain using the Visual Analogue Scale (VAS), and complications. The mean total operative time was 224.3 minutes. The study also found that patients with complete cul-de-sac obliteration had significantly longer operative times and higher estimated blood loss compared to those with partial or no obliteration. Postoperative VAS pain scores showed a significant reduction over a 6-week period. Complications included one case of complete ureteral transection, pelvic hematoma with infection, vaginal abscess, urinary tract infection, and pneumonia., Conclusion: Our findings suggest that RvNOTES may be a feasible surgical approach in expert hands for treating stage IV endometriosis, even in cases with complete obliteration of the cul-de-sac., (Copyright © 2024 AAGL.

Study Objective: To show feasibility and techniques used to perform a total hysterectomy, bilateral salpingectomy, endometriosis resection, and ovarian reconstruction in a patient with a frozen pelvis secondary to a history of ruptured tubo-ovarian abscess., Design: Narrated step-by-step video demonstration., Setting: Single academic institution., Interventions: In patients with a history of multiple abdominal surgeries, abdominal mesh, or in the case of this patient, a history of a ruptured tubo-ovarian abscess, a vaginal approach may be safer. Immediate access to the uterine pedicles through the vagina bypasses the need for extensive enterolysis and adhesiolysis when compared to an abdominal approach. With the use of indocyanine green injected into bilateral ureters, we highlight the benefits of immediate identification of the ureters allowing for safer and more efficient dissection. We show rotational uterine maneuvers to aid in rectosigmoid-to- posterior-uterus dissection in a limited space due to dense pelvic adhesions. Lastly, we demonstrate ovarian reconstruction and oophoropexy for the purpose of easier ovarian identification in future surgeries to possibly reduce the risks of ovarian remnant syndrome., Conclusion: This video highlights the feasibility and strategies used to perform robot-assisted vaginal natural orifice transluminal endoscopic surgery on a patient with a frozen pelvis., (Copyright © 2024 AAGL.

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.

Objective: To reflect on the complications of transvaginal natural orifice transluminal endoscopic surgery (vNOTES), identify the corresponding risk factors, and provide caution to surgeons when performing this novel surgery., Methods: A retrospective study was carried out among 2000 patients in our hospital who underwent vNOTES between May 2019 and May 2022. Perioperative complications were stratified in chronological order and divided into those developed while establishing the vNOTES approach, during surgery, postoperatively, and 1 month after discharge. The complications were classified based on the Modified Clavien-Dindo classifications. The causes of each type III/IV complication were analyzed., Results: Of the 2000 patients, 88 (4.4%) experienced complications, which is not higher than that reported in laparoendoscopic surgery in previous studies. Grade I, II, III, IV, and V complications developed in 19 (0.95%), 57 (2.85%), 11 (0.55%), 1 (0.05%), and 0 (0%) patients, respectively. Complications were developed while establishing the approach platform, during the surgery, postoperatively, and within 1 month after discharge in 5 (0.25%), 30 (1.50%), 50 (2.50%), and 3 (0.15%) patients, respectively. Eight patients (0.4%) underwent conversion, including five cases of rectal injury repair., Conclusion: The summarized suggestions were divided into three levels. Considering the security and effectiveness of vNOTES, it can be routinely used in various gynecologic operations. However, surgeons should focus on preoperative evaluation, strictly conduct preoperative disinfection, conform to prompt conversion during surgery, call for the presence of experienced doctors, and have routine use of antibiotics to prevent postoperative infections., Trial Registration: ChiCTR2100053483., (© 2023 The Authors.

This study aimed to investigate the feasibility, indications, and benefits of transvaginal natural orifice transluminal endoscopic surgery (v-NOTES) hysterectomy for nonmalignant gynecological diseases. The clinical data, including the baseline information and surgical conditions of 81 patients who underwent v-NOTES hysterectomy for nonmalignant gynecological diseases in a tertiary university hospital from October 2018 to August 2022, were retrospectively analyzed and compared with the total laparoscopic hysterectomy group (200 cases) and the transumbilical laparoendoscopic Single Site Surgery group (150 cases). In comparison with the other 2 groups, the highest proportion of patients in the v-NOTES group had cervical intraepithelial neoplasia. Accordingly, mean preoperative uterine volume measured by sonography was significantly smaller in the v-notes group. In the v-NOTES group, the mean number of vaginal deliveries and age were significantly higher, while the mean number of previous abdominal surgeries was lower compared to the other 2 groups. The V-NOTES group had a shorter operation time, shorter postoperative urinary catheter insertion time, earlier intestinal recovery days, shorter hospital stay, and lower visual analogue scale scores after surgery, and the differences were statistically significant. When indicated appropriately, v-NOTES hysterectomy can be a feasible and advantageous surgical modality. In particular, in comparison to the laparoendoscopic Single Site Surgery and total laparoscopic hysterectomy groups, the v-NOTES group had advantages in postoperative recovery and had more aesthetic surgical results., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Objective: Vaginal natural orifice transluminal endoscopic surgery (vNOTES) is widely recognized for its potential benefits, including reducing post-surgical pain and leaving no discernible scarring. However, the anatomical specificity of the vNOTES approach may elevate the risk of nearby organ damage, such as the rectum and bladder. Thus, this study aims to demonstrate the safety and relative merits of vNOTES over transumbilical laparoendoscopic single-site surgery (LESS)., Methods: The Longitudinal Vaginal Natural Orifice Transluminal Endoscopic Surgery Study (LovNOTESS), which was conducted in Chengdu, China. A total of 110 patients who underwent myomectomy in vNOTES or LESS from January 2021 to December 2022. This study prospectively collected and compared perioperative and follow-up data of the two groups., Results: In the vNOTES group, patients had shorter postoperative anal exhaust time, lower pain medications use rate, shorter hospital stay but higher intraoperative conversion rate, and higher postoperative fever rate. vNOTES decreased the anal exhaust time by approximately 8.7 h (95 %CI: -16.182, -1.262, p = 0.007). Moreover, vNOTES reduces pain medication use risk by 73.1 % (OR: 0.269, 95 %CI: 0.172, 0.318, p = 0.016)., Conclusion: Relative to LESS, vNOTES can make patients mitigate postoperative discomfort, accelerate the recovery of gastrointestinal function, curtail hospitalization duration, and enable a more rapid return to daily activities in myomectomy. However, vNOTES has a higher risk of surgical conversion and adjacent organ injury. Therefore, larger scale prospective studies are needed to prove its security and promote the widespread application of vNOTES in myomectomy., 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 Authors.

Iatrogenic stomach perforation is a detrimental, irreversible, and fatal condition. Traditional surgery and endoscopic suturing clips and devices have been introduced to seal holes and prevent sepsis and disease progression. However, the development of endoscopic devices for perforations remains challenging, with no standard device available. This study investigates the superficial layer approximation strengths of the newly designed ENDOCRAB system for gastric wall defects. Thirty porcine stomachs were prepared ex vivo for the perforation model and distributed equally into three groups: ENDOCRAB system, Through-the-Scope Clip (TTSC), and hand suturing (HS). Both ENDOCRAB and TTSC achieved mucosal-submucosal layer apposition, whereas HS allowed a full-thickness layer. Their air leakage pressure and procedural duration were measured. The analysis of air-leakage pressure demonstrated comparable suture strength between ENDOCRAB (118.5 ± 41.7 mmHg) and HS (127.4 ± 30.2 mmHg, P = 0.812), but inferior strength with TTSC (73.6 ± 21.6 mmHg, P = 0.012). HS achieved the shortest procedural duration, whereas ENDOCRAB and TTSC showed no significant differences. The ENDOCRAB system showed significantly greater strength than the TTSC, was comparable to HS in strength, and required a procedural duration similar to that of the TTSC. Furthermore, long-term in vivo experiments and histological evaluations are essential., (© 2024. The Author(s).)

In this report, we described a new technique of gasless V-NOTES for hysterectomy and salpingectomy on a robotic platform with flexible devices in a porcine model. As a result, the gynecological procedures were successfully completed. The total operative time was 110 min, while the docking time was 10 min. The estimated blood loss was estimated to be 10 mL with no intraoperative complications. It revealed that gasless V-NOTES for hysterectomy and salpingectomy on a robotic platform with flexible devices appeared to be feasible and safe in the porcine model and has the potential for clinical use in human beings., (© 2024.

Chemotherapy and radiation therapy can cause gonadal dysfunction in women of reproductive age. Ovarian tissue cryopreservation is performed to restore fertility by allowing transplantation of the patient's frozen-thawed ovarian tissue or through future in vitro maturation and in vitro fertilization of frozen-thawed oocytes. Herein, we describe our initial experience with vaginal natural orifice transluminal endoscopic surgery for ovarian tissue preservation in a young woman with malignant tumor. A 23-year-old woman with anaplastic lymphoma kinase-positive malignant lymphoma was scheduled for hematopoietic stem cell transplantation after experiencing relapse following R-cyclophosphamide, doxorubicin, vincristine, and prednisolone therapy. Ovarian tissue cryopreservation was selected as only MII2 oocytes were collected. Vaginal natural orifice transluminal endoscopic surgery was performed to excise the left ovary. Ovarian tissues were frozen using the vitrification method. The operative time was 37 min, and blood loss was minimal. Pathological examination revealed no metastatic findings of malignant lymphoma and no thermal damage to the ovarian tissue due to bipolar disorder. The patient was discharged on the first day postoperatively, and her postoperative course was uneventful. The vaginal natural orifice transluminal endoscopic surgery technique can provide a safe and effective alternative to laparoscopy or laparotomy for the cryopreservation of ovarian tissue in young patients with cancer. We believe this method has potential application in sexually mature female cancer survivors.

Objectives: Transvaginal natural orifice transluminal endoscopic surgery (vNOTES) and transumbilical laparoendoscopic single-site surgery (LESS) have shown the prospection as minimally invasive procedures. Here we aimed to compare ovarian cystectomy assisted by vNOTES and by LESS for ovarian mature cystic teratoma (OMCT)., Material and Methods: A total of 81 premenopausal women with OMCT were randomized to undergo ovarian cystectomy assisted by either vNOTES (n = 41) or LESS (n = 40). The main outcome was the operative time. Secondary outcomes included the length of hospital stay, visual analog scale (VAS) pain scores, abdominal contamination by teratoma contents, and intraoperative and postoperative complications., Results: There were no intergroup differences in age, body mass index, tumor size, or bilaterality of tumor. The operative time for the vNOTES group was significantly shorter than that for the LESS group (68.41 ± 20.92 min vs 85.05 ± 32.94 min, p = 0.008). The highest VAS pain score 24 hours postoperatively was 1.21 ± 0.48 in the vNOTES group and 2.43 ± 0.57 in the LESS group (p < 0.001). Twenty-four of the 40 patients in the LESS group experienced teratoma rupture intraoperatively, leading to abdominal contamination by the teratoma content, while 5 abdominal contamination was observed in the vNOTES group （p = 0.005. No significant differences between the two groups were observed in the other outcomes., Conclusions: vNOTES assisted ovarian cystectomy has short operative time, fast recovery, no scarring, less pain, and low rate of abdominal contamination. Consequently, vNOTES might be superior to LESS for treating OMCTs.

Transsphenoidal endoscopic surgery is the first-line treatment for growth hormone-secreting adenomas. To analyse the results of the transsphenoidal endoscopic approach for acromegaly and to determine the predictive factors of remission. A single-centre retrospective review was performed in patients who underwent endoscopic transsphenoidal surgery for acromegaly between January 2009 and January 2019. Demographic features, clinical presentation, histopathology records, complications and pre- and postoperative radiologic and endocrinological assessments were evaluated. The factors that influenced the remission rates were investigated. A total of 73 patients underwent surgery via the transsphenoidal endoscopic approach. Cavernous sinus invasion was detected in 32 patients (43.8%); and macroadenoma, in 57 (78%). The pathology specimens of the 27 patients (36.9%) showed dual-staining adenomas with prolactin. A total of 51 patients (69.8%) attained biochemical remission 1 year after surgery. A second operation was performed in 10 patients (13.6%) with residual tumours without biochemical remission in the first year. Six (60%) of the patients attained remission at the last follow-up. Transient diabetes insipidus was observed in 18 patients (24.6%); and rhinorrhoea, which was resolved with conservative treatment, in 4 (5.4%). None of the patients developed panhypopituitarism. The presence of cavernous sinus invasion and preoperative IGF-1, immediate postoperative GH and third-month IGF-1 levels were predictive of remission. Transsphenoidal endoscopic surgery is a safe and effective treatment for acromegaly. Reoperation should be considered in patients with residual tumours without remission. [ABSTRACT FROM AUTHOR]

Objective Unilateral biportal endoscopic (UBE) surgery has recently been used as a minimally invasive procedure for the treatment of lumbar spinal stenosis and is associated with less perioperative blood loss. However, perioperative hidden blood loss (HBL) may be neglected during UBE. This study aimed to examine the volume of HBL and discuss the influential risk factors for HBL during unilateral biportal endoscopic surgery. Methods From January 2022 to August 2022, 51 patients underwent percutaneous unilateral biportal endoscopic surgery for lumbar spinal stenosis at the Department of Spinal Surgery of the Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University and were enrolled in this study. The data included general indicators (age, sex and body mass index [BMI]), underlying disease (hypertension and diabetes), laboratory test results (prothrombin time [PT], activated partial thromboplastin time [APTT], fibrinogen [Fbg]), and preoperative and postoperative hematocrit and hemoglobin), related imaging parameters (severity of intervertebral disc [IVD] degeneration and soft tissue thickness of the interlaminar approach), number of operated vertebrae and operation time. Total blood loss (TBL) and HBL during surgical procedures were measured via the Gross formula. Influential factors were further analyzed by multivariate linear regression analysis and t‐tests. Results The mean HBL was 257.89 ± 190.66 mL for single‐operation patients and 296.58 ± 269.75 mL for two‐operation patients. Patients with lower PT (p = 0.044), deeper tissue thickness (p = 0.047), and diabetes mellitus were determined to have more HBL during UBE. The operation time might also be an important factor (p = 0.047). However, sex (p = 0.265), age (p = 0.771/0.624), BMI (p = 0.655/0.664), APTT (p = 0.545/0.751), degree of degenerated IVD (p = 0.932/0.477), and hypertension (p = 0.356/0.896) were not related to HBL. Conclusion This study determined the different influential factors of HBL during UBE. PT, tissue thickness, and diabetes mellitus are the independent risk factors that affect HBL incidence. Long PT may decrease the volume of HBL within a certain range. Tissue thickness and diabetes mellitus can lead to an increased volume of HBL.

In nasal endoscopic surgery, recurrence of chronic rhinosinusitis is not uncommon which may be due to the trauma and injury viz. bone exposure, fibrous scarring, and ostia stenosis caused by surgical procedure. Here, we have investigated the various factors that contribute to such recurrence. Eligibility assessment was conducted on all patients with chronic rhinosinusitis admitted to our hospital between January 2020 and April 2023, resulting in the recruitment of 200 patients scheduled for nasal endoscopic surgery. After a minimum of 12 months postoperative follow-up, patients included in the final analysis were categorized into recurrence and non-recurrence groups. Through multifactorial logistic regression analysis, smoking, VAS score, pterygoid sinus (S) score, sinus-oral sinus complex (OMC) nasal polyps, allergic rhinitis, deviated septum, and postoperative infection were identified as independent influencing factors for postoperative recurrence (P <0.05). Thus, the factors influencing recurrence after nasal endoscopic surgery in patients with chronic sinusitis comprise smoking, VAS score, lesion extent (AE, S, OMC score), nasal polyps, allergic rhinitis, deviated septum, and postoperative infection. The study concludes that implementing effective clinical interventions targeting these factors is crucial for reducing recurrence rates in patients. [ABSTRACT FROM AUTHOR]

The objective of this study is to evaluate the surgical outcomes for robotic-assisted vaginal natural orifice transluminal endoscopic surgery (R-VNOTES) hysterectomy versus robotic-assisted single-site port (RSSP) hysterectomy when performed for benign indications. This is a retrospective chart review in an academic tertiary setting. 404 patients underwent hysterectomy for benign indications. R-VNOTES hysterectomy and RSSP hysterectomy were performed by a single minimally invasive gynecologic surgeon from January 2015 to August 2022. The primary outcome of our study was total operative time (minutes). Secondary outcomes included estimated blood loss (mL), length of hospital stay (days), and postoperative pain score. Other intraoperative and postoperative surgical complications were also compared. 159 patients underwent R-VNOTES hysterectomy, and 269 patients underwent RSSP hysterectomy. Median length of surgery (minutes) demonstrated a statistically significant shorter operative time in the R-VNOTES hysterectomy group when compared to the RSSP hysterectomy group, (132 min versus 146 min, respectively, p = 0.0001). Additionally, patients in the R-VNOTES hysterectomy group experienced decreased postoperative pain levels at week 1 (6 versus 7, respectively, p = 0.01) and week 3 (1.5 versus 2.5, respectively, p = 0.01) after surgery. There were no statistically significant differences between the two groups when comparing length of hospital stay, estimated blood loss, and weight of the uterus. There was no difference in rates of urinary tract infection, blood transfusion, bowel injury, readmission, reoperation, conversion, deep surgical site infection, and venous thromboembolism between both groups. However, there was a higher rate of superficial SSI in the RSSP hysterectomy group (0.6% versus 4.5%, respectively, p = 0.03). When compared to RSSP hysterectomy, R-VNOTES hysterectomy is safe and feasible, as both approaches have comparable surgical outcomes. Patients undergoing R-VNOTES hysterectomy had shorter length of surgery, decreased postoperative pain, and lower rates of superficial surgical site infections., (© 2023.

This study reviews the progress and recent advances in vaginal natural orifice transluminal endoscopic surgery (vNOTES) as a minimally invasive gynecologic procedure. The proposed advantages of vaginal natural orifice transluminal surgery include enhanced cosmesis due to a scarless procedure, better exposure compared with the pure vaginal approach, tolerable pain scores, fewer perioperative complications, and a shorter hospital stay. Recent advances in surgical instrumentation and technology have improved the feasibility of vNOTES as an innovative treatment option for gynecological conditions. However, technical challenges and training issues must be overcome before its widespread use. As a promising surgical innovation, further randomized comparative studies are required to clarify the safety and effectiveness of vNOTES in gynecology.
