vNOTES Hysterectomy with Sentinel Lymph Node Mapping for Endometrial Cancer: Description of Technique and Perioperative Outcomes. J Minim Invasive Gynecol 2021; 28:1254-1261. [PMID: 33516958 DOI: 10.1016/j.jmig.2021.01.022] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2020] [Revised: 01/08/2021] [Accepted: 01/24/2021] [Indexed: 11/21/2022]
Abstract
STUDY OBJECTIVE To explore the technique and clinical value of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) in hysterectomy and sentinel lymph node (SLN) mapping for endometrial cancer by comparing its perioperative outcomes with those of laparoscopic staging. DESIGN Retrospective cohort study. SETTING Department of gynecology at a tertiary medical center. PATIENTS All women diagnosed with endometrial cancer who underwent minimally invasive surgery at our center between August 2017 and May 2020. INTERVENTIONS Both vNOTES and laparoscopic approaches were used for hysterectomy and SLN mapping. The success of SLN detection as well as perioperative outcomes were subsequently analyzed. MEASUREMENTS AND MAIN RESULTS This study included 74 patients; 23 patients underwent vNOTES surgery, whereas 51 underwent standard laparoscopic surgery. The total successful SLN detection was 95.7% in the vNOTES group and 92.2% in the laparoscopy group (p >.05), whereas the bilateral success rates were 87.0% and 90.2%, respectively. No difference in SLN detection was observed between the 2 groups in terms of the side-specific mapping efficacy quotient (91.3% vs 91.2%, p = .47). The number of harvested SLNs, operative time, estimated blood loss, and intraoperative complications in the 2 groups were similar. One (4.3%) postoperative complication occurred in the vNOTES group vs 4 (7.9%) in the laparoscopy group (p = .029), and the median postoperative hospital stay was 3 days vs 4 days (p = .003). CONCLUSION This study suggests that the vNOTES procedure is feasible, with a potentially decreased postoperative hospital stay, faster recovery, and better cosmetic results. However, prospective research is needed to validate its broader clinical application.

Abstract
BACKGROUND Natural orifice transluminal endoscopic surgery (NOTES) in urology is becoming more and more interesting due to technical innovations. One of those innovations is the HybridKnife®, a multifunctional sonde that combines high-frequency electrosurgery and water jet surgery. The aim of this study was to establish a transrectal, flexible endoscopic retroperitoneoscopy in a porcine model by means of the HybridKnife® for further development of a transrectal retroperitoneal NOTES lymphadenectomy (NOTES-RLA). MATERIAL AND METHODS Five female pigs (25-30 kg body mass) were anesthetized and placed in a supine position. The rectal mucosa was opened 3-5 cm cranially of the linea dentata. After submucosal tunneling, the retrorectal space was opened. We performed a flexible endoscopic retroperitoneoscopy by means of a double-channel gastroscope 13.806 PKS (Karl Storz-Endoskope, Tuttlingen, Germany) and the HybridKnife® I-type (ERBE Elektromedizin, Tübingen, Germany). RESULTS Transrectal access was safe and feasible without any difficulties. Using the HybridKnife® water jet technology, the retroperitoneal space could be distended which enabled safe access to the iliacal vessels, the bifurcation of the aorta/vena cava, and the pre- and paraaortal/-caval space up to the renal vessels. The water jet did not lacerate or injure blood vessels, nerves, or lymph vessels in any of the surgical procedures. CONCLUSIONS By means of the HybridKnife®, transrectal access into the retrorectal space is safe and easily feasible. The water jet technology combined with electrosurgery prevented injuries of blood vessels, nerves, and lymph vessels and enabled transrectal flexible endoscopic retroperitoneoscopy as a precondition for further establishment of a transrectal NOTES-RLA.

Abstract
Natural orifice transluminal endoscopic surgery (NOTES) has gained a great deal of attention from gastroenterologists and surgeons all over the world since its introduction in 2000. The field of NOTES has advanced tremendously since that time and exciting and well-designed research has been reported. Both randomized controlled trials and results from large national and international registries have been published. Many experimental and clinical studies have discussed transesophageal, transgastric, transvaginal and transrectal access for a variety of NOTES procedures. Transvaginal access has been the most frequently reported NOTES access route in clinical trials. When suitable instruments become available, a true comparison of NOTES with current laparoscopic approaches can be realized.

Abstract
The early diagnosis of gastric cancer allows patients and physicians to pursue the option of endoscopic resection, which is significantly less invasive than conventional surgical resection. In Korea, the use of endoscopic submucosal dissection (ESD) has been increasing, and many reports on ESD have been published. In addition, Korean gastroenterologists from several hospitals performing ESD have conducted formal meetings to discuss useful information regarding ESD. Here, we discuss the Korean experience with ESD, including outcomes and prospects of endoscopic treatments.

Abstract
The practice of gynecologic surgery has been revolutionized by laparoscopic techniques in the past decades. Nowadays minimal invasive procedures are feasible and safe standard options in the management of most benign and malignant gynecologic diseases. Natural orifices transluminal endoscopic surgery (NOTES) and laparoendoscopic single-site surgery (LESS) have been developed in an attempt to further reduce the morbidity and scarring with minimal invasive procedures. These techniques share a common conception that a reduction in the number of transcutaneous points of access may benefit patients in terms of port-related complications, risk of hernia formation, recovery time, pain and cosmetics by potentially performing scarless surgery. The development of LESS has been facilitated by the concept of scarless surgical procedures. Increasing experience revealed by recent publications have allowed for the expansion of NOTES and LESS techniques in the gynecologic surgery. Almost all laparoscopic procedures can be performed by acquiring these concepts. Although these surgical methods are feasible and safe, certain technical problems (e.g. loss of triangulation, problems of visualization, ergonomic considerations) has yet to be solved and several questions must be answered before LESS and NOTES could gain widespread acceptance as single procedures. Despite successful technical developments these methods remain investigational approaches and refinement of indications as well as further development of instrumentation are expected to define its area of future application.

Abstract
The aims of the ANUBIS™ project developed in IRCAD-Strasbourg were to evaluate the concept and the potentialities of natural orifices transluminal endoscopic surgery (NOTES), to develop a specific instrumentation, to translate the research work into clinical settings and to provide education and training. To achieve these goals, an intensive collaboration was established between IRCAD, which comprises medical staff (surgeons, gastroenterologists, gynaecologists), computer scientists and robotics engineers, and industrial partners. Between 2005 and 2008, more than 400 experimental procedures were performed on inanimate models, ex-vivo tissues, animal models and human cadavers. Cholecystectomy was defined as the procedure that would realize the translation of experimental work into the clinical setting. The first human transvaginal cholecystectomy was performed at the end of the second year of the project. Transgastric cholecystectomy followed six months later. A new concept of therapeutic flexible endoscope (Anubiscope™, Storz Endoskope,Tutlingen, Germany) was developed, and different modalities of closure of the viscerotomies were elaborated. Implementation of the experimental program into the clinical setting and translation of technological research into a finalized industrial product were achieved thanks to a rigorous, extensive and stepwise study of the potentialities of NOTES. Education and training were organized and 500 participants attended the specific courses and hands-on sessions organized at IRCAD-EITS.

Abstract
INTRODUCTION Esophageal achalasia is most commonly treated by laparoscopic myotomy. Transesophageal approaches using flexible endoscopy have recently been described. We hypothesized that using techniques and flexible instruments from our NOTES experience through a small cervical incision would be a safer and less traumatic route for esophageal myotomy. The purpose of this study was to evaluate the feasibility, safety, and success rate of using flexible endoscopes to perform anterior or posterior Heller myotomy via a transcervical approach. METHODS This animal (porcine) and human cadaver study was conducted at the Legacy Research and Technology Center. Mediastinal operations on ten live, anesthetized pigs and two human cadavers were performed using standard flexible endoscopes through a small incision at the supra-sternal notch. The esophagus was dissected to the phreno-esophageal junction using balloon dilatation in the peri-esophageal space followed by either anterior or posterior distal esophageal myotomy. Success rate was recorded of esophageal dissection to the diaphragm and proximal stomach, anterior and posterior myotomy, perforation, and complication rates. RESULTS Dissection of the esophagus to the diaphragm and performing esophageal myotomy was achieved in 100% of attempts. Posterior Heller myotomy was always extendable onto the gastric wall, while anterior gastric extension of the myotomy was found to be more difficult (4/4 and 2/8, respectively; P = 0.061). CONCLUSION Heller myotomy through a small cervical incision using flexible endoscopes is feasible. A complete Heller myotomy was performed with a higher success rate posteriorly possibly due to less anatomic interference.

Abstract
PURPOSE OF REVIEW Since its introduction in 2000, natural orifice translumenal endoscopic surgery (NOTES) has gained a great deal of attention from gastroenterologists and surgeons all over the world. In this article, we will review the progress in the field of NOTES and present the latest publications that provide some answers and solutions to the barriers suggested by the Natural Orifice Surgery Consortium for Assessment and Research white paper. RECENT FINDINGS Because of the first human NOTES procedure by Rao and Reddy, more pioneering procedures, including transgastric and transvaginal cholecystectomies, appendectomies, and hernia repairs, have been performed. Although NOTES researchers continue to experiment with new innovative equipment and procedures in the lab, more structured work, including randomized controlled trials, has been published. SUMMARY In the last several years, there has been growing interest in NOTES, which has translated into exciting animal research work and publication of randomized controlled trials. Additionally, preliminary NOTES human procedures have been successfully performed. When suitable instruments become available, the subsequent step should be comparing NOTES with current laparoscopic approaches. Superiority or even equality of NOTES to laparoscopic surgery would be the best argument for advancing and integrating implementation into clinical practice.

Abstract
NOTES ("natural orifice transluminal endoscopic surgery") has the potential to optimize minimally invasive surgery. In gynecology there is extensive experience with the transvaginal approach to the abdominal cavity. It is easy to perform, closure is safe and there is little risk of infection. Hence, this is the approach most suitable for NOTES. By means of rigid laparoscopic instruments cholecystectomy can be routinely performed. Such operations could be performed in 149 patients in our hospital and the NOTES register of the DGAV has data on more than 900 transvaginal operations.

Abstract
AIM: To develop a pure transvaginal access to the retroperitoneum, that is simple, reproducible and uses endoscopic material available on the market.
METHODS: From February 2008 to April 2009, 31 pigs were operated on, with 17 as an acute experiment and 14 with a survival protocol. The animals were placed in a supine position and a 12-mm double-channel endoscope (Karl Storz™, Tuttlingen) was used for vision and dissection. During the same time period, the access experiment was reproduced on 3 human cadavers using material similar to that used in the animal model.
RESULTS: In the animal model, 37 interventions were done on the kidney, adrenal gland and pancreas. The mean time to fashion the access was 10 min (range 5 to 20 min). No intraoperative death was observed. Two major (5%) intraoperative complications occurred: one hemorrhage on the aorta and one tearing of the right renal vein. Peritoneal laceration was encountered in 5 cases without impairing the planned task. In the survival group, good clinical outcome was observed at a mean follow-up of 3 wk (range 2 to 6 wk). In the 3 cadavers, access was performed correctly. The mean time to fashion the access was 52 min (range 40 to 60 min). All the anatomical landmarks described in the pig model were clearly identified in the same sequence.
CONCLUSION: A retroperitoneal natural orifice translumenal surgical transvaginal approach is feasible in both animal and human models and allows performance of a large panel of interventions.

Abstract
BACKGROUND Natural orifice translumenal endoscopic surgery (NOTES) is a major conceptual change in the field of modern surgery. However, corresponding technological refinements are not yet available to fill the gap separating the current laparoscopy from the NOTES of the future. Meanwhile, "hybrid" NOTES techniques, including single-port procedures, have been increasingly reported. This report describes a technique of single-incision laparoscopic appendectomy (SILA) for selected patients with acute appendicitis. METHODS Patients with noncomplicated acute appendicitis, excluding those with abscess, perforation, peritonitis, previous surgery, or obesity, underwent SILA. The procedure was performed using a single 15-mm-diameter umbilical incision with two 5-mm-diameter port sites. RESULTS The study enrolled 36 women and 19 men with a mean age of 28 years (range, 18-78 years). The procedure was achieved for 41 patients (74.5%). The mean operative time was 39 min (range, 14-111 min). There was no mortality. The postoperative complication rate was 5.4% (3 complications in 3 patients), and the median hospital stay was 39 h (range, 8-240 h). CONCLUSION The SILA technique is safe and feasible for selected patients with noncomplicated acute appendicitis. Compared with other transumbilical techniques of appendectomy, SILA has the advantages of feasibility without endoscopic skills and an acceptable operative time. Technical refinements and accomplished learning probably will enable its wider use for more patients with acute appendicitis.

Abstract
Natural orifice translumenal endoscopic surgery (NOTES) allows access into the peritoneal cavity with a flexible endoscope, through the wall of the digestive or urogenital tracts. NOTES can be combined to laparoscopic surgery in so-called << hybrid >> techniques. In the absence of any incision of the abdominal wall, NOTES procedures provide perfect cosmetic results, with virtually no risk of parietal complications, and with decreased postoperative pain. NOTES could particularly benefit to overweight patients and to patients receiving intensive or palliative care. Most NOTES studies have been performed on animal models, with great interest for both transgastric and transpelvic approaches. Successful NOTES peritoneoscopy, hysterectomy, oophorectomy, tubal ligation, gastrojejunal anastomosis, cholecystectomy, splenectomy, nephrectomy, and abdominal-wall hernia repair have been described. In human studies, the transvaginal route is preferred. NOTES clinical research focuses on low-morbidity procedures, such as cholecystectomy, appendectomy, and peritoneoscopy. Indirect benefits are expected from this research, with possible technological innovations in the field of endoscopic instrumentation (including sutures, anastomosis, traction and triangulation). Overall, NOTES is believed to make evolve both interventional endoscopy and minimally invasive surgery.

Abstract
BACKGROUND/PURPOSE The initial idea behind natural orifice transluminal endoscopic surgery (NOTES) was that of an incisionless surgery. NOTES cholecystectomy is a good model of human ingenuity and technological advance. NOTES cholecystectomy in a human being was performed at our institution after extensive laboratory work in live pig models. In this process we gained helpful information related to NOTES cholecystectomy. METHODS More than 250 cholecystectomies in pigs have been performed. From May 2007 to November 2008 a total of 10 and 6 transvaginal and transgastric human cholecystectomies, respectively, have been performed. RESULTS The procedure was successful in all patients, with a mean operative time of 120 min. There were no intraoperative or postoperative complications. Patients recovered promptly after surgery and had minor postoperative pain. They were discharged on the second postoperative day. CONCLUSIONS The advantages of laparoscopy appeared to be enhanced by this approach: patients had minor postoperative pain and minimal scarring. This stepwise experience in the cholecystectomy procedure is an important first step in the development of methods and devices to enable the evaluation of potential incisionless NOTES surgery. Additional research and comparison studies are needed for further improvement in order to provide NOTES procedures to a wider range of patients.
