Bioluminescent Endoscopic Imaging: Technical Requirements of the Chemistry and Camera System
Objective: Bioluminescent chemistry can be infused as an angiography media and by developing endoscopic techniques for bioluminescent imaging (BLI) we have previously demonstrated sensitive visualization of anatomic structures, including the biliary tree and vascular beds. In nature bioluminescence is light produced by a chemical reaction within a living organism. In BLI applications, a luciferin (the… Continue Reading
Chopstick Surgery: A Novel Technique Enables Use of the Da Vinci Robot to Perform Single Incision Laparoscopic Surgery (SILS)
INTRODUCTION: Single incision laparoscopic surgery (SILS) is limited by the coaxial arrangement of the instruments. A surgical robot with “wristed” instruments could overcome this limitation but the “arms” often collide when working coaxially. This study tests a new technique of “chopstick surgery” to enable use of the robotic arms through a single incision without collision.METHODS:… Continue Reading

Clinical Experience with a Multifunctional Flexible Surgery System for Endoluminal, Singe Port and NOTES Procedures
Introduction: Single port and incisionless surgical approaches hold the promise of fewer complications, reduced pain, faster recovery and improved cosmesis compared to traditional open or laparoscopic ones. The ability to select an access approach (i.e., endolumenal, single port, trans-vaginal or trans-gastric) with one platform may be important to optimizing individual patient results.We report our results… Continue Reading

Clinical Predictors of Operative Complexity in Laparoscopic Ventral Hernia Repair: A Prospective Study
Introduction: Due to uncertainties about the complexity of laparoscopic ventral hernia repair in varying patient populations, surgeons may be reluctant to perform this procedure. The aim of this study is to delineate risk factors that can be identified in the preoperative setting that predict longer operative times and complexity in laparoscopic ventral hernia repair. Methods:… Continue Reading

Comparison of Resolution and Improvement of Co-morbidities Between Laparoscopic Sleeve Gastrectomy and Laparoscopic Adjustable Gastric Band.
Introduction: The aim of this study was to compare the rate resolution and improvement of common co-morbidities: type 2 diabetes mellitus (DM), hypertension (HTN), degenerative joint disease (DJD), obstructive sleep apnea (OSA), gastroesophageal reflux disease (GERD), dyslipidemias (LPD) and asthma after Laparoscopic Sleeve Gastrectomy (LSG) or Laparoscopic Adjustable Gastric Band (LAGB).Methods: Retrospective chart review of… Continue Reading

Computer-based Haptic and Nonhaptic Virtual Reality Surgical Simulators: Performance Characteristics and Perceptions of New Users
Background: In order to define the value and perception of importance of haptic features in virtual reality (VR) laparoscopic simulators, we evaluated the initial experience of surgeons using both haptic and nonhaptic simulation devices in the performance of an advanced laparoscopic task.Methods: At the 2008 SAGES meeting, 68 Learning Center attendees were randomized to use… Continue Reading

Development and Validation of Mental Practice As a Training Strategy for Laparoscopic Surgery
BackgroundConcerns for patient safety have rendered the need for alternative training strategies outside of the operating-theatre. Mental Practice (MP), ‘the cognitive rehearsal of a task prior to performance,’ has been successful in sport and aviation to enhance imagery and thus skill. This study aims to develop and validate a MP training strategy for laparoscopic surgery.MethodA… Continue Reading

Diagnostic Transgastric Endoscopic Peritoneoscopy: Extension of Initial Human Trial for Staging of Pancreatic Head Masses
OBJECTIVE(S): We validated Natural Orifice Translumenal Endoscopic Surgery (NOTES) in a human trial of ten patients undergoing diagnostic transgastric endoscopic peritoneoscopy (DTEP) for staging of pancreatic head masses. Reported herein is an update with 10 additional patients.METHODS: Patients in this IRB approved human trial were scheduled to undergo diagnostic laparoscopy for abdominal staging of a… Continue Reading

Differential Expression of Mmp-2 in the Gastrohepatic Ligament of the Gastroesophageal Junction
Introduction: Ligamentous attachments maintain the normal anatomical position of the gastroesophageal (GE) junction. Failure of these elastic ligaments through an alteration in collagen synthesis, deposition and metabolism may be a primary etiology of hiatal hernia formation. Differential expression of zinc-dependent matrix metalloproteinases (MMPs) is largely responsible for collagen remodeling. The purpose of this study was… Continue Reading

Does Preoperative Endoscopy in Bariatric Surgery Alter the Medical or Surgical Strategy?
Introduction: Controversy exists as to the need for preoperative esophago-gastro-duodenoscopy (EGD) for patients undergoing bariatric surgery. Specifically, do findings alter the medical and surgical management. The purpose of this study is to evaluate the role of preoperative EGD in the therapeutic strategy of bariatric surgery. Methods: We conducted a retrospective analysis of consecutive patients undergoing… Continue Reading
Endoscopic and Manometric Characteristics of the Gastroesophageal Valve in Lateral Decubitus and Upright Positions in Clinically Normal Patients
Background: The relationship between body position and the gastroesophageal junction (GEJ) has been subject to intense interest in its role in gastroesophageal reflux disease (GERD). Few studies have looked at the position related changes of the gastroesophageal valve (GEV) in asymptomatic individuals.Purpose: To define the normal physiology of the GEJ in left lateral decubitus (LLD)… Continue Reading
Endoscopic Thyroidectomy for Multinodular Goiter
Introduction: Surgery for multinodular goiter disease typically requires a modest cervical incision to access and extract the diseased thyroid gland. Endoscopic thyroid surgery has become increasingly popular as a result of improved visualization of critical anatomy as well as improved overall cosmetic outcome by avoiding the typical cervical neck incision. In an effort to maximize… 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
