INTRODUCTION: Our group has previously demonstrated the feasibility of NOTES rectosigmoid resection in a swine cadaver model using TEM alone or in combination with transgastric endoscopic assistance to extend the length of colon mobilization. METHODS: A survival study of transanal endoscopic rectosigmoid resection with stapled coloanal anastomosis was conducted in swine using TEM (n=8) and […]
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 […]
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 […]
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 […]
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 […]
