Project description:ObjectiveThe goal of this research was to investigate the feasibility, safety, and short-term clinical outcome of pure extraperitoneal sacrocolpopexy with transvaginal natural orifice transluminal endoscopic surgery (V-NOTES) for treating central pelvic defects.Material and methodsA total of 9 patients with central pelvic prolapse underwent extraperitoneal sacrocolpopexy with V-NOTES, at the Chengdu Women's and Children's Central Hospital, Chengdu, Sichuan, China, between December 2020 and June 2022. The patients' demographic characteristics, perioperative parameters, and clinical outcomes were analyzed retrospectively. Each patient had the following major surgical procedures: (1) Establishing a platform for an extraperitoneal approach with V-NOTES; (2) separating the extraperitoneal path to the sacral promontory region; (3) suturing the long arm of the mesh to the anterior longitudinal ligament S1; and (4) suturing and fixating the short arm of the mesh at the top of the vagina.ResultsThe median patient age was 55, the median operative time was 145 minutes, and the median intraoperative blood loss was 150 mL. The operations were successful for all 9 cases, with a median preoperative Pelvic Organ Prolapse-Quantification score of C: +4, and a 3-months postoperative score of C: -6. There were no recurrences during a follow-up of 3-11 months, and no complications occurred, such as mesh erosion, exposure, and infection.ConclusionAs a new surgical approach, extraperitoneal sacrocolpopexy with V-NOTES is safe and feasible.

Project description:PurposeNatural orifice transluminal endoscopic surgery (NOTES) is a novel technique in minimally invasive surgery whereby a flexible endoscope is inserted via a natural orifice to gain access to the abdominal cavity, leaving no external scars. This innovative use of flexible endoscopy creates many new challenges and is associated with a steep learning curve for clinicians.MethodsWe developed NOViSE-the first force-feedback-enabled virtual reality simulator for NOTES training supporting a flexible endoscope. The haptic device is custom-built, and the behaviour of the virtual flexible endoscope is based on an established theoretical framework-the Cosserat theory of elastic rods.ResultsWe present the application of NOViSE to the simulation of a hybrid trans-gastric cholecystectomy procedure. Preliminary results of face, content and construct validation have previously shown that NOViSE delivers the required level of realism for training of endoscopic manipulation skills specific to NOTES.ConclusionsVR simulation of NOTES procedures can contribute to surgical training and improve the educational experience without putting patients at risk, raising ethical issues or requiring expensive animal or cadaver facilities. In the context of an experimental technique, NOViSE could potentially facilitate NOTES development and contribute to its wider use by keeping practitioners up to date with this novel surgical technique. NOViSE is a first prototype, and the initial results indicate that it provides promising foundations for further development.

Project description:BackgroundPatient benefits from natural orifice transluminal endoscopic surgery (NOTES) are of interest in acute-care surgery. This review provides an overview of the historical development of NOTES procedures, and addresses their current uses and limitations for intra-abdominal emergency conditions.MethodsA PubMed search was carried out for articles describing NOTES approaches for appendicectomy, percutaneous gastrostomy, hollow viscus perforation and pancreatic necrosectomy. Pertinent articles were reviewed and data on available outcomes synthesized.ResultsEmergency conditions in surgery tax the patient's cardiovascular and respiratory systems, and fluid and electrolyte balance. The operative intervention itself leads to an inflammatory response and blood loss, thus adding to the physiological stress. NOTES provides a minimally invasive alternative access to the peritoneal cavity, avoiding abdominal wall incisions. A clear advantage to the patient is evident with the implementation of an endoscopic approach to deal with inadvertently displaced percutaneous endoscopic gastrostomy tubes and perforated gastroduodenal ulcer. The NOTES approach appears less invasive for patients with infected pancreatic necrosis, in whom it allows surgical debridement and avoidance of open necrosectomy. Transvaginal appendicectomy is the second most frequently performed NOTES procedure after cholecystectomy. The NOTES concept has provided a change in perspective for intramural and transmural endoscopic approaches to iatrogenic perforations during endoscopy.ConclusionNOTES approaches have been implemented in clinical practice over the past decade. Selected techniques offer reduced invasiveness for patients with intra-abdominal emergencies, and may improve outcomes. Steady future development and adoption of NOTES are likely to follow as technology improves and surgeons become comfortable with the approaches.

Project description:ObjectivesThe vaginal surgical approach has not become the standard of care, despite its advantages. The Hominis™ Surgical System is a humanoid shaped robot-assisted system that was designed specifically for robotic vaginal natural orifice transluminal endoscopic surgery (RvNOTES). We aimed to present our experience with the first RvNOTES bilateral salpingo-oophorectomy (BSO) performed by the Hominis system.Study designA two-center prospective study of BSO by RvNOTES in women with nonmalignant indications conducted between August and December 2018. Women older than 18 years were offered to participate. Exclusion criteria included a history of abdominal malignancy, pelvic or abdominal irradiation, Crohn's disease, pelvic inflammatory disease, severe infections in the lower abdomen, active diverticulitis, deep infiltrating recto-vaginal endometriosis, and an active vaginal infection. The primary outcome of the study was the rate of conversion to open or laparoscopic approaches. Secondary outcomes included intra- and postoperative adverse events, operative time, estimated blood loss, length of hospital stay, and 6-week follow-up assessment.ResultsEight women aged 50-70 years with BMI of 19-30 kg/m2 were recruited. All the procedures were completed successfully without conversions to open surgery. No intraoperative complications were observed. Median blood loss was 10 mL (range: 10-50). The median duration of the procedure was 45 min (range: 38-91), and decreased over the study period. Surgeons' usability assessment was very favorable, with a median of 5 on a 1-5 scale. The median visual analog scale (VAS) score was 1 (range: 1-3).ConclusionsThis is the first documentation of a surgery performed via the vagina using robotic instrumentation developed for this purpose. The disruptive technology of RvNOTES, with its fast learning curve, will make gynecological surgeries accessible to more women.

Project description:Background: Minimally invasive surgery could improve cosmetic outcomes and reduce the risks of surgical injury with less postoperative pain and a quicker patient's discharge. Recently, transvaginal natural orifice transluminal endoscopic surgery (vNOTES) has been introduced in urogynecology with exciting results. Evidence Acquisition: After PROSPERO registration (n°CRD42023406815), we performed a comprehensive literature search on Pubmed, Embase, and Cochrane CENTRAL, including peer-reviewed studies evaluating transvaginal natural orifice transluminal endoscopic surgery. No limits on time or type of study were applied. Evidence synthesis: Overall, 12 manuscripts were included in the analysis. Seven studies evaluated uterosacral ligament suspension, four studies evaluated sacral colpopexy, three evaluated sacrospinous ligament suspension, and one study evaluated lateral suspension. Overall success rates were high (>90%); however, definitions of success were heterogeneous. In terms of complication, most of the studies reported low-grade complications (Clavien-Dindo I and II); only two patients needed mesh removal because of mesh exposure. The risk of bias of the trials was rated in the medium to high-risk category. Conclusions: The present review highlights important initial results for vNOTES. Future randomized clinical trials are needed to better define its role in the management of urogynecological procedures.

Project description: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.

Project description:Despite guidelines that assert that the vaginal route for benign hysterectomy is preferred as the most minimally invasive approach, rates of vaginal hysterectomy remain very low in the United States. Vaginal natural orifice transluminal endoscopic surgery (vNOTES) might reverse the trend. Potential advantages of vNOTES compared to traditional laparoscopic and robotic approaches include the potential for less pain, decreased operative time, improved cosmesis, and decreased risks. Importantly, vNOTES might allow for the conversion of laparoscopic and robotic routes back to vaginal due to surgeon factors.

Project description: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.
