Evaluation for Double Balloon Sealing of Gastric Perforation in Transgastric NOTES
IntroductionTransgastric route is one of the most major accesses in NOTES. Gastric perforation has been the major challenge because of the risk of peritonitis and consequent complications. The original gastric incision is usually dilated because of the constant movement of the endoscope, the dislodgement of the endoscope from gastric orifice prolongs the procedure time. To… Continue Reading

Using a Flexible Robotic Endoscopic NOTES Platform Transgastrically in a Cadaver to Test Access, Navigation, Maneuverability and Stability
OBJECTIVE: The advancement of NOTES highly depends on the availability of suitable platforms and instruments. A NOSCAR working group has identified access, navigation, maneuverability and stability to withstand instrument forces as essential requirements for a successful NOTES platform. No platform used for NOTES to date can adequately achieve all four of these key capabilities. Here… Continue Reading

Ergonomic User Interfaces for NOTES; A Comparison of Learning Curves for Open, Laparoscopic and Endoscopic Devices in Complex Bimanual Coordination
Background: NOTES adds a novel paradigm to surgical techniques. In the NOTES paradigm, it may require long periods of training to overcome difficulties in interpreting unstable images and controlling flexible instruments in order to master basic surgical skills. This study takes an initial step into understanding the learning process of NOTES. Bimanual coordination learning curves… Continue Reading

Transgastric Endoscopic Bloodles Liver Resection Using Radiofrequency Thermal Energy. An Experimental Study
Obsective: To assess the feasibility and safety of transgastric endoscopic assisted hepatectomy using percutaneous radiofrequency thermal energy(PRF) in a porcine model.Methods: Fourteen domestic male white pigs with a mean weight of 17.6 kg (range 15 to 21 kg) were used. Under general anesthesia a standard upper double-lumen endoscope was advanced perorally into the stomach A… Continue Reading

Completely Transvaginal NOTES Cholecystectomy in a Porcine Model Using Novel Endoscopic Instrumentation
Introduction: Transvaginal NOTES Cholecystectomy has been successfully performed but all reports have required laparoscopic assistance. The purpose of this study was to perform completely transvaginal cholecystectomy in a porcine model.Methods: Pigs 1-5 underwent non-survival and Pigs 6-8 underwent 14-day survival procedures. Through a vaginotomy, a 2T gastroscope and an 18mm x 38cm access port were… Continue Reading

Reverse NOTES: Esophageal Canalization
Introduction: Traditional natural orifice translumenal endoscopic surgery (NOTES) involves entry through a pre-existing orifice such as the mouth, anus or vagina. A surgically created “orifice” such as a gastrostomy can also be used as an access site, performing a reverse NOTES surgery. This video describes such reverse access to treat a complete esophageal occlusion following… Continue Reading

A Novel Active Overtube for Endoscopic Treatment of Colorectal Tumors
A NOVEL ACTIVE OVERTUBE FOR ENDOSCOPIC TREATMENT OF COLORECTAL TUMORSKazuhiko Shinohara MD, Gennai Yanagisawa MScSchool of Bionics, Tokyo University of Technology, Tokyo, JapanObjective: Endoscopic resection for early colorectal tumors is minimally invasive treatment, however it requires long operation times and skillfulness to complete the en-bloc resection in safety. This weak point is caused by the… Continue Reading

Small Bowel Resection and Anastomosis Using \”notes\”: Lessons Learned in a Survival Model
INTRODUCTION: Natural orifice translumenal endoscopic surgery (NOTES) has been used for a number of technically straightforward surgical procedures. However, to date, no one has reported using NOTES technique for small bowel resection and anastomosis in a survival model.METHODS AND PROCEDURES: All studies were conducted in accordance with Institutional Animal Care and Use Committee (IACUC) protocols.… Continue Reading

Peritoneal Inflammatory Response of Natural Orifice Translumenal Endoscopic Surgery (notes) Versus Laparoscopy with Carbon Dioxide and Air Pneumoperitoneum
Background: The immunologic and physiologic effects of NOTES are poorly understood when compared to traditional surgical approaches. Previous experimental models have shown NOTES and laparoscopy share similar acute-phase systemic inflammatory cytokine profiles, except for a possible late phase TNF-a depression in NOTES. The local immunologic peritoneal reaction and immunomodulatory influence of pneumoperitoneum agents are also… Continue Reading

Gastrointestinal Bacterial Clearance Levelizer for NOTES Using a Cleaning Unit and a Digital Image Analyzer with a Confocal Laser Microscope
In NOTES, it is mandatory to maintain a high bacterial clearance level in the gastrointestinal tract, the route of access to intraperitoneal cavity. In NOTES that is conducted through the lower gastrointestinal tract that is convenient among routes of access to intraperitoneal cavity, it is very difficult to obtain a bacterial clearance level at which… Continue Reading

Transvaginal NOTES Partial Gastrectomy for Gastric Submucosal Tumors: Early Experience in Humans
Introduction: Transvaginal endoscopic gastric surgery is one of the cutting edge procedures in the field of natural orifice translumenal endoscopic surgery (NOTES). Its feasibility has been shown sporadically in bariatric cases, however, not in oncologic conditions. We report our early experience with hybrid transvaginal NOTES gastrectomy for gastric submucosal tumors (SMTs).Methods: Two female patients with… Continue Reading

National Study of Higher Surgical Trainees As Endoscopists –
IntroSurgical training in England is once again in the midst of a vast upheaval. The introduction of the European Working Time Directive (EWTD) combined with shortened training time poses problems with regards to sufficient exposure to procedures for surgical trainees. This clearly has implications with regards to the role of the surgeon as an endoscopist,… Continue Reading

Effectiveness of a New Trocar System to Enable NOTES
Introduction: Natural orifice translumenal endoscopic surgery (NOTES) is a developing area of minimally invasive surgery. Fundamental challenges of NOTES include development of safe ways to perform translumenal access and maintaining visualization and spatial orientation using a stable operating platform. This study examines the functionality of a new rotary access needle (RAN) device and technique for… Continue Reading
