Vaginal natural orifice transluminal endoscopic surgery (vNOTES) for colorectal cancer utilizes transvaginal access for bowel mobilization, vascular pedicle ligation, oncological resection, and bowel anastomosis, along with subsequent transvaginal natural orifice specimen extraction (NOSE), reducing or eliminating the need for transabdominal access. In this report, we describe the technique of vNOTES right hemicolectomy for cecal cancer, with intracorporeal anastomosis and transvaginal NOSE, including a step-by-step operative video. The patient was a 59-year-old Chinese female (body mass index 32.0 kg/m2) with a cT3N0M0 3 cm cecal adenocarcinoma. Posterior colpotomy was created with insertion of a dual-ring wound protector. vNOTES D2 right hemicolectomy with a fully stapled intracorporeal anastomosis was performed via a homemade transvaginal glove port, using extra-long rigid instruments. A 10 mm, 30° rigid laparoscope was used for operative visualization through a transumbilical port, without additional percutaneous trocars. Operative difficulties pertained to suboptimal instrument reach, lack of triangulation, and frequent clashing within the restricted access space. Surgical duration was 300 min, with 50 ml of blood loss. There was minimal postoperative pain. Return of bowel function occurred on postoperative day 2, with discharge from hospital on postoperative day 3. The patient resumed normal daily activities and regular diet by 1-week post-surgery. Self-reported cosmetic satisfaction score was excellent. No operative complications were observed at 2 months\' follow-up. vNOTES right hemicolectomy with intracorporeal anastomosis is safe and feasible in highly selected colon cancer patients. Operators should be proficient in conventional laparoscopic colectomy and transvaginal NOSE. More experience with the vNOTES technique is required to ascertain best practices.

UNASSIGNED: Vaginal assisted Natural Orifice Transluminal Endoscopic Surgery (NOTES) combines the benefits of vaginal and endoscopic surgery. This study presents the results of the first vaginal assisted NOTES hysterectomies (VANH) in The Netherlands.
UNASSIGNED: A prospective cohort study was performed in two non-academic teaching hospitals in The Netherlands. Data was collected from patients who underwent a VANH for benign indications between August 2019 and April 2023. Baseline characteristics and data of intra- and postoperative surgical outcomes were recorded and analysed. The VANHs were performed by four experienced vaginal and endoscopic gynaecological surgeons.
UNASSIGNED: A total of 200 patients underwent a VANH. Indications were dysfunctional menstrual bleeding (61 %; n = 122), abnormal cervical cytology (15.5 %; n = 31), abdominal pain (11.5 %; n = 23), post ablation/sterilization pain syndrome (3.5 %; n = 7), uterine fibroids (5.0 %; n = 10), atypical endometrial hyperplasia (2.5 %; n = 5) and Lynch or BRCA gene mutation carriers (1.0 %, n = 2). The mean surgical time was 61.4 min ( ± 22.8 min) with a mean blood loss of 88 mL ( ± 89 mL) and a mean uterine weight of 150 g ( ± 112 g). In 2.0 % (n = 4) of the cases a conversion was necessary. Same day discharge (SDD) was feasible in 80.2 % (n = 105) of the patients planned in day-care. In 2.0 % (n = 4) an intra-operative complication and in 9.0 % (n = 18) a post-operative complication occurred.
UNASSIGNED: This study shows vNOTES to be a safe and feasible surgical technique and can be safely implemented with appropriate patient selection and skilled surgeons. It highlights the importance of surgeon awareness of the challenges inherent in the initial stages of the implementation of a new surgical technique when performing their first vNOTES procedures. Additional randomized clinical trials are needed to show superiority of vNOTES compared to traditional surgery.

UNASSIGNED: To evaluate safety, efficacy, pre- and postoperative outcomes of vNOTES hysterectomy compared to conventional laparoscopic (CL) hysterectomy.
UNASSIGNED: This prospective study was conducted on patients who underwent CL or vNOTES hysterectomy for benign gynecological indications between January and July 2021. Sociodemographic, clinical, and surgical data were collected. Health-related quality of life (HRQoL) outcomes were evaluated using the EQ-5D-5L questionnaire.
UNASSIGNED: A total of 228 patients (CL vs. vNOTES: 147 vs. 81) were included. No significant differences were observed between the two groups in terms of blood loss, uterine weight, complications, length of hospital stay, and readmission rate. Patients in the vNOTES group experienced significantly less postoperative pain and required less analgesia compared to those who underwent CL hysterectomy (p < 0.001). The CL group had a shorter operative time (p < 0.001). There was a significant difference between the two groups in the EQ-5D-5L pain/discomfort dimension (p = 0.047).
UNASSIGNED: This research showed that vNOTES has various advantages, such as less postoperative pain, reduced analgesic usage, and better HRQoL outcomes three months after surgery.

BACKGROUND: Vaginal hysterectomy (VH) rate is declining despite being considered as the optimal minimally invasive option for hysterectomy with reduced operative time and length of stay compared with laparoscopic hysterectomy (LH). Vaginal assisted natural orifice transluminal endoscopic surgery hysterectomy (VANH) combines the advantages of both vaginal and endoscopic approach to surgery.
OBJECTIVE: To report feasibility and early experience of a single surgeon adopting VANH at a tertiary Australian hospital.
METHODS: Prospective review of the first 20 VANH cases with complete data set collected retrospectively including patient demographics, indication for surgery and perioperative outcomes.
RESULTS: The median age of the first 20 participants was 51.5 years (47-57 years of age) and the median body mass index was 33.5 kg/m2 (27.8-38.3 kg/m2). The predominant indication was complex hyperplasia with atypia (12/20, 60%). The median parity was two (1-3) where four patients were nulliparous. The median blood loss was 125 mL (100-200 mL) with an operative time of 149 min (138-198 min) and median weight of the specimen of 181.5 g (66.5-219 g). The mean length of stay was 1.4 days (1-2 days). Five cases had conversion to laparoscopy and the majority (80%) occurred within the first ten cases.
CONCLUSIONS: VANH is feasible but there is a learning curve to achieve competence in this technique, which requires adequate training in the early stages of adoption with careful case selection. Until further robust data is available to determine the clinical benefit and safety profile of VANH, patients should be carefully counselled and the decision on mode of hysterectomy be individualised.

BACKGROUND: To explore the possibility of treatment with VNOTES sentinel lymph node dissection concept in patients with endometrial cancer.
METHODS: Patients who underwent VNOTES sentinel lymph node biopsy with the Comba modification were compared to patients who underwent conventional laparoscopic sentinel lymph node biopsy performed by the same surgical team. A total of 38 patients who underwent sentinel lymph node biopsy + total laparoscopic hysterectomy and bilateral salpingo-oophorectomy (BSO) were compared with 19 patients who underwent VNOTES retroperitoneal sentinel lymph node biopsy + hysterectomy and BSO. Surgical steps were described.
RESULTS: The average operation time, perioperative blood loss, the number of sentinel lymph nodes, presence of complications, and preoperative-postoperative hemoglobin-hematocrit differences, tumor stages, grades, largest tumor diameter, depths of invasion, and histological subtypes were similar in both the VNOTES and conventional laparoscopy groups. The postoperative pain scores were lower and the hospital stay was shorter in the VNOTES group than in the conventional laparoscopy group. No disease recurrence had been detected in either group at the time of writing.
CONCLUSIONS: Compared to conventional laparoscopy, sentinel lymph node biopsy with the VNOTES technique provides similar surgical results and is more advantageous in terms of postoperative pain and hospital length of stay.

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.
BACKGROUND: This study retrospectively registered with the China Clinical Trial Registry with the registration number ChiCTR2100052223(22-10-2021).

Urinary incontinence affects 25-45 % of women with the gold standard surgical approach being placement of mid-urethral synthetic slings; tension-free vaginal tape (TVT) and trans-obturator tape (TOT). Due to the controversies regarding vaginal mesh the last decade, an increasing demand has evolved for incontinence treatment without vaginal synthetic mesh. The short term results of autologous rectus fascia sling for TOT surgery have shown similar success rates compared to those after the use of synthetic mesh, but the harvesting of the mesh is less minimally invasive and is associated with longer surgical time. vNOTES is a combination of a vaginal entrance to the abdomen and endoscopy via the vagina. The aim with the video is to show a new surgical technique with a fully vaginal, scarless vNOTES approach for harvesting the posterior rectus fascia for TVT and TOT procedures.

(1) Background: Sentinel lymph node (SLN) mapping represents an accurate and feasible technique for the surgical staging of endometrial and cervical cancer. This is commonly performed by conventional laparoscopy or robotic-assisted laparoscopy, but in recent years, a new retroperitoneal transvaginal natural orifice transluminal endoscopic surgery (vNOTES) approach has been described and developed by Jan Baekelandt. This technique provides easy visualization of lymphatic afferent vessels and pelvic lymph nodes, early SLN assessment, and a coherent mapping methodology following the lymphatic flow from caudal to cranial. However, only a few publications have reported it. Following the IDEAL (Idea Development Exploration Assessment Long-term follow-up) framework, research concerning this technique is in Stage 2a, with only small case series as evidence of its feasibility. Its standardized description appears necessary to provide the surgical homogeneity required to move further. (2) Methods: Description of a standardized approach for retroperitoneal pelvic SLN mapping by vNOTES. (3) Results: We describe a 10-step approach to successfully perform retroperitoneal vNOTES SLN mapping, including pre-, intra-, and postoperative management. (4) Conclusions: This IDEAL Stage 2a study could help other surgeons approach this new technique, and it proposes a common methodology necessary for evolving through future IDEAL Stage 2b (multi-center studies) and Stage 3 (randomized controlled trials) studies.

UNASSIGNED: As the second most common surgery performed on women in the United States, hysterectomy techniques are constantly examined for validity and superiority. The vaginal natural orifice transluminal endoscopic surgery (vNOTES) has increased in popularity since the first vNOTES hysterectomy was performed in 2012. We sought out to evaluate the safety and effectiveness of hysterectomy by vNOTES compared to conventional vaginal hysterectomy for various benign indications.
UNASSIGNED: We searched Scopus, Medline, PubMed, ClinicalTrials.Gov, and the Cochrane Library. Our search included all studies from each respective database\'s inception until September 1, 2023.
UNASSIGNED: We included eligible studies that compare vNOTES hysterectomy versus conventional vaginal hysterectomy for various benign indications, and included at least one of our preselected outcomes. The main outcomes were estimated blood loss (mL), operation time (min), length of hospital stay (d), Visual Analogue Scale pain score at Day 1, intraoperative complications, and postoperative complications.
UNASSIGNED: We analyzed data of our continuous outcomes using RevMan 5.4.1. Continuous outcomes were analyzed using mean difference (MD) and 95% confidence intervals (CIs) under the inverse variance analysis method. We assessed the quality of the studies using the ROBINS-I assessment tool.
UNASSIGNED: We found 4 eligible studies to include in our analysis. Surgeon declared estimated blood loss was found to be similar in both groups (MD=-44.70 [-99.97, 10.57]; P=.11). Also, the total length of hospital stay (in days) was found to be comparable in both groups (MD=-0.16 [-1.62, 1.30]; P=.83). We also found no other statistically significant difference between hysterectomy by vNOTES and vaginal hysterectomy in other studied outcomes, including the duration of the operation, the Visual Analogue Scale Pain score after 1 day, intraoperative complications, and postoperative complications.
UNASSIGNED: vNOTES seems to be associated with a nonsignificant lower surgeon declared estimated blood loss. We found no other significant differences in hospital stay, intraoperative, or postoperative outcomes. Further studies may clarify if other differences in safety or efficacy exist.

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.
CONCLUSIONS: 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.
