A Multitasking Platform for NOTES; A Bench Top Comparison of a New Device for Flexible Endoscopic Surgery and Standard Dual Channel Endoscope * *supported By a Noscar Grant (2006)
Background: Complex surgery requires precise, independent coordination of two instruments that can perform multiple tasks such as traction and counter traction, precise dissection, and tissue approximation. All of these are difficult to achieve with standard dual channel scopes, which have been used for most of the human NOTES cases today. The development of a multitasking… 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

NOTES Approach to Endoscopic Gastropexy: Feasibility Study in Dogs
NOTES procedures are more invasive than traditional endoscopy because they involve exiting the lumen of a hollow organ, tissue manipulation, and closure of the access site. We proposed that a novel endoscopic gastropexy utilizing a NOTES approach results in secure adhesions with few complications. To further study the impact of NOTES, we chose to evaluate… 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

Who\’s Afraid of Natural Orifice Translumenal Endoscopic Surgery (notes)?
Introduction: Intraabdominal surgery using a flexible endoscope combines the skills of both gastroenterologists (GI) and minimally invasive surgeons (MIS). Deficiencies in each of these standard training models include the lack of familiarity with complex intraabdominal maneuvers, for physicians with a GI background, and difficulty operating without a fixed horizon, for those with an MIS background.Materials… Continue Reading

The Diagnostic Efficacy of Natural Orifice Translumenal Endoscopic Surgery (notes): Is There a Role in the Intensive Care Unit?
Background: Evaluation of a potential source of abdominal sepsis in a critically ill patient can be challenging. With flexible endoscopy being readily available in this setting, we sought to evaluate the diagnostic efficacy of a trans-gastric NOTES peritoneoscopy vs. laparoscopic exploration in the identification of common intra-abdominal pathology in a porcine model.Methods: In this acute… Continue Reading

Magnetic Retraction of the Gallbladder During NOTES Transvaginal Cholecystectomy in a Porcine Model: A Novel Technique
Introduction: As the advent of the NOTES era dawns, novel techniques for tissue retraction may be necessary to allow for safe surgical procedures to be performed. There have been multiple case reports of magnets being used to help with retraction during NOTES procedures. Most of these reports employ some type of metallic object placed on… Continue Reading

Transesophageal Mediastinal Lymph Node Sampling.
1. Objective of the study: Improved minimally invasive lymph node sampling for cancer staging and diagnosis of mediastinal lymphadenopathy is desirable. Natural orifice approaches may offer improved minimally invasive options. We have previously reported on the technical feasibility and the potential low risk of transesophageal mediastinoscopy using the submucosal endoscopy with mucosal flap safety valve… Continue Reading

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

The Development and Testing of a Tethered, Independent Camera for NOTES and Single-site Laparoscopic Procedures
Background:“Tunnel vision” associated with flexible endoscopes used in NOTES and rigid laparoscopes used in Single Site Laparoscopic (SSL) procedures can present the surgeon with a disorienting view of familiar surroundings. Because the working tools are in-line with the view in these approaches, it is also difficult to achieve adequate instrument triangulation, a critical component of… Continue Reading

Transvaginal Diagnostic Peritoneoscopy in Women with Pelvic Pain
Purpose: Chronic pelvic pain affects many women in reproductive age in the US and laparoscopy is common in the diagnostic algorithm. In the realm of NOTES, a transvaginal approach would be a natural approach to reduce incision sites, postoperative pain and improve cosmesis in this patient population. This is the first report of transvaginal diagnostic… Continue Reading
