Evidence about intra‐ and postoperative complication rates related to transvaginal natural orifice transluminal endoscopic surgery (vNOTES) for benign gynecological conditions is still limited. We report and analyze data from a large cohort of patients operated in a single institution during 3.5 years.

To evaluate the safety and feasibility of vaginal natural orifice transluminal endoscopic surgery (vNOTES) for benign gynaecological indications.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.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(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).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.Copyright © 2020.

The current standard treatment for endometrial cancer is a laparoscopic hysterectomy with adnexectomies and bilateral sentinel node resection. A retroperitoneal vNOTES sentinel node resection has several theoretical potential advantages. These include being less invasive, leaving no visible scars, operating without Trendelenburg, and therefore offering the anesthetic advantage of easier ventilation in obese patients and following the natural lymph node trajectory from caudally to cranially and therefore a lower risk of missing the sentinel node. The aim of this study is to determine the feasibility of a retroperitoneal vNOTES approach to sentinel lymph node dissection for staging of endometrial cancer.

Surgical staging is essential in the management of ovarian cancers. This staging has traditionally been performed by laparotomy, but minimally invasive techniques are increasingly employed. Transvaginal natural orifice transluminal endoscopic surgery (vNOTES) is a promising technique in the field of gynecological oncology. We report 2 cases of vNOTES surgical staging for suspicious ovarian tumors. We operated on 2 patients aged of 81 and 62 years for low-grade serous ovarian carcinoma and ovarian cystadenofibroma, respectively. We performed surgical staging with a pure vNOTES technique for the first patient and used a hybrid approach for the second. No intraoperative or postoperative complications were observed. We suggest that vNOTES is a feasible and effective approach to surgically manage early-stage ovarian cancers.

Transvaginal surgery is the most minimally invasive surgery for a gynecologic procedure. A 67-year-old woman who had four children with vaginal deliveries and one abortion, with no underlying disease and a body mass index of 22.4 kg/m, came to the hospital due to menorrhagia. Her diagnosis was myoma uteri from an asymptomatic palpated mass at the lower abdomen. The ultrasonography showed a 9 cm × 5.9 cm myoma mass at the anterior wall of the uterus. After counseling, the transvaginal natural orifice transluminal endoscopic surgery (NOTES) operation was conducted on May 2018. The process was a transvaginal NOTES hysterectomy following a transvaginal NOTES-assisted myomectomy. The uterine weight was 376 g. In this case, the surgeons could not enter into the pelvic cavity completely because the myoma mass was attached to the bladder which led to the surgeons safely performing the transvaginal NOTES myomectomy before the hysterectomy.Copyright: © 2020 Gynecology and Minimally Invasive Therapy.

Adhesion at the vesicouterine fold presents a great challenge when performing hysterectomy through transvaginal natural orifice transluminal endoscopy surgery (NOTES) in women with a history of cesarean section. An attempt to lyse adhesions often prolongs the procedure and may inadvertently result in cystostomy. The purpose of this report is to demonstrate a safe technique for the lysis of vesicouterine adhesions during NOTES hysterectomy. We present the cases of two patients with a history of cesarean section. Severe adhesions at the vesicouterine peritoneum were encountered in both cases, and one patient had an extensive adhesion involving lower half of the uterus. Although the lateral approach is sufficient in most cases, it does not allow a surgeon to approach the peritoneal cavity if there is extensive adhesion. In cases such as these, direct dissection of the adhesion on the uterus is required.

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.

Advances in surgical techniques and perioperative management are the two major contributing factors to improved surgical outcomes. The purpose of the current study was to compare the efficacy of single-port surgery and perioperative enhanced recovery after surgery (ERAS) management in laparoscopic myomectomy.The present study included 120 patients undergoing laparoscopic myomectomy in the Gynecological Ward of Quzhou Affiliated Hospital of Wenzhou Medical University. According to the traditional perioperative management mode and ERAS management, multi-port and single-port procedures, all patients were assigned to the Conventional-SPLS (Single-Port Laparoscopic Surgery with conventional perioperative care) group (n = 34), Conventional-Multi (multi-port laparoscopic surgery with conventional perioperative care) group (n = 47), and ERAS (multi-port laparoscopic surgery with ERAS perioperative care) group (n = 39). The surgical outcomes of the three groups were compared operation time, intraoperative blood loss, variations in postoperative hemoglobin, postoperative walking time, postoperative flatus expelling time, postoperative hospital stay, and visual analog scale (VAS) scores at 6 and 12 h following surgery.The ERAS group recovered the quickest in terms of postoperative walking time and flatus expelling duration. The ERAS group also recovered the shortest postoperative hospital stay (3.85 ± 1.14 days), which differed significantly from that in the Conventional-Multi group, but not significantly from that in the Conventional-SPLS group. In terms of VAS scores at 6 and 12 h after surgery, the ERAS group had the lowest pain intensity, which differed significantly from that of the other two groups. The effect of surgical procedures or postoperative care on hospital stay was assessed using multiple regression analysis. The results demonstrated that ERAS was an important independent contributor to reducing postoperative hospital stay (β = 0.270, p = 0.002), while single-port surgery did not affect this index (β = 0.107, p = 0.278).In laparoscopic myomectomy, perioperative ERAS management could control postoperative pain and shorten hospital stay. Single-port surgery could speed up the recovery of gastrointestinal function and postoperative walking time, but it did not affect postoperative pain management or the length of hospital stay. Thus, the most effective approach to improving postoperative outcomes in laparoscopic myomectomy was the application of perioperative ERAS management.© 2023. The Author(s).

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).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.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).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.Copyright © 2024 The Authors. Published by Elsevier B.V.

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.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.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.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.Copyright © 2021 Elsevier B.V.

Laparoscopic myomectomy (LM) is one of the techniques feasible for the treatment of intramural myoma. This technique is reported to be difficult when large fibroids are involved because of excessive blood loss during surgery. Skillful and fast suturing appears to be associated with reduced blood loss during LM. In this study we compared the surgical outcomes of using bidirectional Stratafix® barbed suture versus conventional suture during LM.

Hysterectomy may have an effect on the pelvic floor. Here, we evaluated the rates and risks for pelvic organ prolapse (POP) surgeries and visits among women with a history of hysterectomy for benign indication excluding POP.
