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 […]
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 […]
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 […]
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 […]
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 […]
