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:Patient 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.A 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.Emergency 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.NOTES 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: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:Objective: The 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 Methods: A 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. Results: The 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. Conclusion: As a new surgical approach, extraperitoneal sacrocolpopexy with V-NOTES is safe and feasible. (J GYNECOL SURG 39:108)

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.

Project description:This current case report describes an elderly woman with pyometra that underwent successful vaginal hysterectomy and transvaginal natural orifice transluminal endoscopic surgery (vNOTES) bilateral adnexectomy after conservative anti-inflammatory drug treatment. The patient had a history of transvaginal delivery so this approach was considered the most appropriate. To the best of our knowledge, this is the first report to investigate the use of vaginal hysterectomy and vNOTES bilateral adnexectomy in an elderly patient with pyometra. The necessary steps to the procedure are shown in a narrated instructional video.

Project description:IntroductionTransvaginal natural orifice transluminal endoscopic surgery (vNOTES) is an emerging technique in the area of minimally invasive surgery. Vaginal leiomyoma is a rare benign tumor, with only a few cases being reported in the literature. we demonstrate a novel approach for excision of a vaginal leiomyoma via vNOTES. To ensure reproducibility and replicability akin to a standardized procedure, we have provided a step-by-step video description of the use of vNOTES for upper anterior vaginal myomectomy.Patient concernsA 35-year-old female (G2P0A2) presented with a tumor in the upper anterior vaginal wall, which gradually increased in size.DiagnosisA vaginal examination revealed a swollen area approximately 3-cm in diameter on the upper anterior vaginal wall. The swelling was mobile and solid. All other vitals were normal. Transvaginal ultrasound detected a 3.0 × 3.4 cm hypoechogenic mass on the superior vaginal wall, and a preoperative diagnosis of the vaginal tumor was confirmed.InterventionsThe upper vaginal leiomyoma treated using transvaginal natural orifice transluminal endoscopic surgery.OutcomesThe procedure lasted for 20 min, and the postoperative course was uneventful.ConclusionsvNOTES can be a promising alternative to traditional vaginal surgery for upper vaginal disease due to advantages such as excellent exposure, easy access and precise suturing. However, more studies are needed to assess its long-term efficacy.
