Endoscopic Myotomy of the Lower Esophageal Sphincter – A Model for Gastroesophageal Reflux.
1. Objective of the study: A reproducible animal model for gastroesophageal reflux would aide in advancing endoscopic intralumenal therapies for GERD. In this study we performed a full thickness myotomy through the lower esophageal sphincter (LES) onto the gastric cardia incorporating our submucosal endoscopy with mucosal safety flap (SEMF) technique in efforts to establish a… 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

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

Evaluation of a Viscerotomy Formation and Closure Device for Natural Orifice Surgery in a Survival Model
Introduction: The most challenging of the many hurdles surgeons must overcome to safely perform NOTES is viscerotomy closure. The perfect device must be easy to deploy, can be used on any viscera, and will create a rapid, reliable and durable closure. To date, new devices created for this purpose have fallen well short of these… Continue Reading

Flexible Endoscopic Scissors: A Comparative Study
INTRODUCTION: The long length and small diameter of endoscopic working channels present significant design obstacles for instruments such as endoscopic scissors that require reliable function and strong closing force. This study compares the function of four endoscopic shears.METHODS: Endoscopic scissors from four companies were trialed - the Olympus FS-3L-1 (Olympus, Tokyo, Japan), EES Prototype Device… Continue Reading

Functional and Comparative Evaluation of Flexible Monopolar Endoscopic Scissors.
1. Objective of the study: The success of natural orifice translumenal endoscopic procedures requires reliable, accurate tissue dissection and suture cutting comparable to current laparoscopic tools. A prototype flexible endoscopic scissor for tissue biopsy, dissection, enterotomy creation and suture cutting was evaluated.2. Description of the methods: Acute study in 2 domestic pigs. Laparoscopic access provided… Continue Reading

Gastric Bypass Pouch Revision and Stoma Plication: A Novel Technique Using a New Endoluminal Suturing Device
Weight regain following gastric bypass has been associated with enlargement of the gastric pouch and with dilation of the gastro-jejunal anastomotic stoma. We developed a new technique for revision of the pouch and stoma using a novel endolumenal suturing device in an ex vivo model porcine stomach model. The novel prototype device is a flexible… 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

Gynecologic Status After NOTES Transvaginal Cholecystectomy
Background: the development of NOTES procedures and its clinical application raise issues regarding the ways of access to the abdominal cavity. The transvaginal access through posterior colpotomy has been widely used by gynecologists for the treatment of several conditions and eliminates the disadvantages associated with other NOTES approaches ( transgastric, transrectal and trans-vesical). Objective: assessment… Continue Reading

Human Gallbladder Measurements and Implications for Natural Orifice Surgery
Background: Natural orifice translumenal endoscopic surgery (NOTES) introduces a paradigm shift in minimally invasive surgery that may benefit patients with decreased post-operative pain, faster recovery, better cosmesis, and less surgical morbidity by reducing abdominal incisions. While several NOTES and hybrid-NOTES cholecystectomies have been performed throughout the world, much research is needed to refine the technique,… Continue Reading

Hybrid NOTES Cholecystectomy: Prospective Human Series
Introduction. Natural orifice transluminal endoscopic surgery (NOTES) makes it possible to perform intraperitoneal surgical procedures with a minimal number of access points in the abdominal wall. It is not yet possible at the present time to perform these interventions without the help of abdominal wall entryways, so these procedures are hybrids, a fusion of minilaparoscopy… Continue Reading

Hybrid Transvaginal NOTES Sleeve Gastrectomy in a Pocine Model Using a Magnetically Anchored Camera and Novel Instrumentation
Introduction: The purpose of this study was to determine the feasibility of transvaginal NOTES sleeve gastrectomy using novel instrumentation in a porcine model.Methods: Anesthetized pigs (non-survival (n=7), 14-day survival (n=1)) underwent sleeve gastrectomy procedures. Under endoscopic visualization, a 25mm x 40cm access port was inserted through a vaginotomy into the peritoneal cavity using blunt dissection… Continue Reading

Indications for Natural Orifice Transluminal Endoscopic Surgery in Surgical Oncology
Introduction:Recent publications suggest that transluminal interventions may be a promising alternative to laparoscopy in the field of minimal invasive surgery. Until now it remains unclear which endoscopic technique should be applied and which access route is considered safe and feasible. Possible indications for natural orifice transluminal surgery (NOTES) are still under discussion. Methods:From May 2007… Continue Reading

Intraoperative Cardiopulmonary Effects of Natural Orifice Translumenal Endoscopic Surgery (notes) Compared to Traditional Surgery
Introduction: Interest in natural orifice translumenal endoscopic surgery (NOTES) is fueled by the possibility that it may represent a less invasive method of abdominal surgery. To objectively evaluate this, we compared the intraoperative cardiopulmonary effects of NOTES versus traditional surgery.Materials and Methods: Nine mongrel dogs undergoing bilateral inguinal herniorrhaphy (BIH) were used for this study.… Continue Reading
