Trans Oral Endoscopic Stapled Esophago Diverticulostomy (toesed ) for Zenker\’s Diverticulum
Introduction: Zenker's diverticulum is a known cause for dysphagia and is treated usually by resection or diverticulopexy through a neck incision. In recent years an endoscopic per-oral method has been described. A cohort of patients was treated and long-term follow up was obtained.Materials and Methods: All patients presented with the diagnosis of Zenker's diverticulum were… Continue Reading

How Can Inadvertent Intestinal Insufflation Be Limited in Complex Intragastric NOTES Procedures?
Objective: Early experience with transgastric NOTES in animal models have demonstrated the consequences of inadvertent insufflation of the small and large bowel. The resultant crowding of the intestines increases the risk of ensnaring the bowel during transgastric suturing. A mechanism for limiting transpyloric insufflation but permitting the necessary intragastric working space is needed.Description: A NOTES… Continue Reading

Endoscopic Gastrojejunostomy Using the Full Thickness Plications
Objectives: Natural Orifice Translumenal Endoscopic Surgery (NOTES) utilizes resectional or anastomotic techniques. Anastomotic work to date is limited to suturing and stapling devices. Endoscopic gastrojejunostomy has been reported in two animal studies. The aim of our study is to assess feasibility of gastrojejunostomy with full thickness plications.Methods: Six ex vivo porcine stomachs were prepared with… Continue Reading

Evaluation of a Novel Air Seal Access Port for Transvaginal NOTES Cholecystectomy
Introduction: We previously reported successful transvaginal NOTES cholecystectomy in porcine models but experienced difficulty with pneumoperitoneum gas leakage when Magnetic Anchoring and Guidance System (MAGS) and endoscopic instruments were used in conjunction with conventional trocar seals. The purpose of this study was to evaluate the utility of a novel access port for this procedure.Methods: Non-survival… Continue Reading

Optimizing Magnetically Anchored Camera, Light Source, Graspers, and Cautery Dissector for Transvaginal NOTES Cholecystectomy
Introduction: We previously reported successful transvaginal NOTES cholecystectomy in a porcine model using a Magnetic Anchoring and Guidance System (MAGS). The purpose of this study was to further optimize MAGS instruments for this procedure.Methods: Preliminary in-vivo testing (n=1) and complete non-survival procedures (n=3, 33-34kg) were performed in pigs. Through a vaginotomy created under direct vision,… Continue Reading

Endoscopic Transgastric Peritoneoscopy for Intestinal Ischemia in a Porcine Model
INTRODUCTIONIntestinal ischemia is difficult to diagnose in a critically ill patient. Natural orifice transluminal peritoneoscopy may provide us with a valuable diagnostic tool that can be performed at the bedside with minimal equipment requirements with a potential for a high sensitivity in detecting ischemic bowel. The aim of this study is to develop a bowel… Continue Reading

NOTES Pancreatic Pseudocystgastrostomy: a Human NOTES Anastomosis
Introduction: Natural orifice transluminal endoscopic surgery (NOTES) is a technique where an operation is performed across the lumen of a hollow viscus without the aid of an abdominal incision. Much of the early work in NOTES has utilized a transgastric approach due to ease of endoscope passage through the mouth. Pancreatic pseudocysts have long been… Continue Reading

Use of Endoluminal Therapies for Obese Patients with GERD
Introduction: Body mass index > 30 is a preoperative predictor of failure after antireflux surgery, limiting therapeutic options for obese patients with medically refractory GERD. This study seeks to evaluate outcomes after two different endoluminal GERD therapies for these patients.Methods: Obese patients (BMI>30) presenting with medically-refractory GERD underwent either a single endoscopic full thickness (EFT)… Continue Reading

Two layer closure of gastrotomy following transvaginal and transgastric peritoneoscopy in an animal model
BackgroundNatural orifice translumenal endoscopic surgery (NOTES) is a newly developing technology in the surgical field. Methods of gastrotomy closure are still far from satisfactory and pose a major hindrance to the development of NOTES. A new concept of transvaginal and transgastric peritoneoscopy followed by a two-layer endoclip closure of gastrotomy wound is presented.MethodsFour pigs were… Continue Reading

Colonic Sterilization for NOTES Procedures – a Comparison of Two Decontamination Protocols
Introduction:In the 2005 White Paper, prevention of infection was named as one of the ten potential barriers to performing NOTES surgery. The aim of this study was to evaluate the effect of two different sterilization protocols on the bacterial counts in the swine colon while preparing for NOTES surgery.Methods:After placing a proximal colon balloon, 16… Continue Reading

Natural Orifice Translumenal Endoscopic Surgery with a Miniature in Vivo Surgical Robot
Introduction: The application of flexible endoscopy tools for Natural Orifice Translumenal Endoscopic Surgery (NOTES) is constrained due to limitations in dexterity, instrument insertion, navigation, visualization, and retraction. Miniature endolumenal robots that are not constrained by the natural orifice can mitigate these constraints through providing a stable platform for visualization and dexterous manipulation. This video demonstrates… Continue Reading

NOTES: Cadaveric Rendezvous Hybrid Small Bowel Resection
Natural Orifice Translumenal Endoscopic Surgery (NOTES) is an emerging field in minimally invasive surgery that is driving the development of new technology and techniques. Before NOTES gains widespread popularity, it must be proven to be a safe and efficacious technique. There are several proposed benefits of the NOTES approach. Among these benefits are a potentially… Continue Reading

Natural Orifice Translumenal Endoscopic Drainage for Pancreatic Abscesses
INTRODUCTION: Endoscopic pseudocyst drainage is well documented, but few series describe endoscopic drainage of pancreatic abscesses. Abscesses are complications of pancreatitis, presenting with sepsis and/or peritonitis. We report the feasibility and efficacy of natural orifice translumenal endoscopic surgery for pancreatic abscesses. METHODS: We reviewed consecutively treated patients (1994-2007). Approaches alone or in combination were: (1)… Continue Reading

New Technique for Gastrotomy Closure in NOTES and its Comparison with Endoclips
INTRODUCTION: Numerous experimental studies have been conducted to evaluate, explore, and develop Natural Orifice Transluminal Endoscopic Surgery (NOTES). The results have been varied ranging from mediocre to excellent. The most common challenge and perhaps the main limiting factor for the progress of NOTES has been the issue of adequate and effective gastrotomy closure. We describe… Continue Reading

Transanal endoscopic microsurgery (T.E.M) treatment of rectal cancer: A comparision of outcomes with and without neoadjuvant radiation therapy
Introduction: Improved tumor downstaging and complete response rates of rectal cancer treated with neoadjuvant therapy have been observed. There has been concern that the detrimental, local effect of radiation makes this approach unsuitable for excision. We compared 2 groups of patients undergoing comparable TEM surgery, with and without neoadjuvant radiation. Methods: All patients undergoing TEM… Continue Reading
