INTRODUCTION: Safe esophageal closure remains a challenge in transesophageal Natural Orifice Transluminal Endoscopic Surgery (NOTES) procedures. Suturing or t-tag devices are time consuming and risk organ injury due to their blind deployment. Endoclips are difficult to place in the narrow esophagus and submucosal tunneling techniques do not necessarily prevent leakage of esophageal contents into the […]
Background:Traditional approach for surgical management of mature pancreatic pseudocysts is by internal drainage by cystgastrostomy or cystjejunostomy via open or laparoscopic approaches. Endoscopic drainage procedures have been described; however, they require multiple interventions and are sometimes not definitive. We describe NOTES® (Natural Orifice Translumenal Endoscopic Surgery) stapled cystgastrostomy as a less invasive surgical procedure for […]
Introduction: A conventional method of mesh fixation in laparoscopic ventral hernia repair is transfascial sutures with tacks. This method has been associated with low recurrence rates, but yields significant morbidity from pain and bleeding. Fibrin glue has been used successfully in inguinal hernia repairs with decreased incidence of chronic pain without an increase in recurrence […]
Objective: Instruments featuring articulation of the distal tip are highly desirable when access to the surgical site is restricted, as in Single Port Laparoscopic Surgery. This study compares two types of articulating instruments which have different means of controlling the distal articulation – a controlling wheel and a controlling joint – in terms of ergonomics […]
Objective: The constraints imposed by the minimal access surgical approach have driven the need for enabling technologies for vessel occlusion and tissue welding. The objective of this study is to determine the values of, and interaction between, temperature, apposition force and clamp time for optimum tissue welding.Methods: A dedicated experimental step up including a specially […]
