Evaluation of a Viscerotomy Formation and Closure Device for Natural Orifice Surgery in a Survival Model
Introduction: The most challenging of the many hurdles surgeons must overcome to safely perform NOTES is viscerotomy closure. The perfect device must be easy to deploy, can be used on any viscera, and will create a rapid, reliable and durable closure. To date, new devices created for this purpose have fallen well short of these… Continue Reading

Follow-up and Distance From Centre Are Important Determinants in Weight Loss Post Laparoscopic Adjustable Gastric Banding.
IntroductionIn this study, we examine the importance of regular post-operative follow-up and the effect of geographical distance from the centre of follow-up on long term weight loss post laparoscopic adjustable gastric banding (LAGB). MethodOver 11 years (1997- 2008), 140 patients underwent LAGB. Post-operatively patients were invited to attend a monthly nurse-led follow-up clinic, to assess… Continue Reading

Gages: A Valid Measurment Tool for Technical Skills in Flexible Endoscopy
Introduction: GAGES (Global Assessment of Gastrointestinal Endoscopic Skills) was created to provide an objective measure of endoscopic skills to better assess training curricula. Pilot data have shown GAGES to meet high standards of reliability and validity. The aim of this multicenter study was to demonstrate the practicality and external validity of this instrument, while providing… Continue Reading

Gastric Electric Stimulation for Severe Gastroparesis
Objective: The purpose of this study is to investigate the effect of gastric electrical stimulation (GES) on solid phase gastric emptying, total symptom score (TSS), health-related quality of life (HRQOL), and patient satisfaction in patients with severe drug refractory gastroparesis. Design: Prospective single-center study Setting: Community hospital Patients: 40 consecutive patients presenting between 2002 and… Continue Reading

Gastrointestinal Recovery After Laparoscopic Partial Large Bowel Resection: Results of a Prospective, Observational, Multicenter Study
Introduction: A prospective, multicenter, observational study (14CL401) investigated gastrointestinal (GI) recovery, length of hospital stay (LOS), and postoperative ileus (POI)-related morbidity after laparoscopic bowel resection (LBR). Methods: Adult patients undergoing LBR with primary anastomosis performed by straight (SL) or hand-assisted (HAL) laparoscopy with scheduled postoperative intravenous patient-controlled analgesia were enrolled. The study design was similar… Continue Reading

Goals -based Assessment of Resident Skill in Advanced Laparoscopic Cases
INTRODUCTION: We hypothesized that GOALS (Global Operative Assessment of Laparoscopic Skills) would have construct validity for laparoscopic cases beyond cholecystectomy and appendectomy.METHOD: Attending surgeons at our institution use a web-based GOALS scoring sheet to evaluate PGY1 through PGY5 residents immediately after all operations. We reviewed all data entered from 7/04 to 5/08 for the following… Continue Reading

Gynecologic Status After NOTES Transvaginal Cholecystectomy
Background: the development of NOTES procedures and its clinical application raise issues regarding the ways of access to the abdominal cavity. The transvaginal access through posterior colpotomy has been widely used by gynecologists for the treatment of several conditions and eliminates the disadvantages associated with other NOTES approaches ( transgastric, transrectal and trans-vesical). Objective: assessment… Continue Reading

Hand Assisted Laparoscopic Splenectomy Is the Superior Approach in Spleens Over 20cm in Length
IntroductionWe report our experience with the Hand Assisted Laparoscopic Splenectomy (HALS) technique and attempt to answer the question of which spleens benefit from HALS. Initial problems with complication rates in laparoscopic splenectomy for splenomegaly have now been refuted. Critics are still concerned with the longer operative times and conversion rates of HALS compared to open… Continue Reading

Hepatic Adiponectin and Leptin in Morbidly Obese Patients
Background: Pathologically, hepatic changes are common in morbidly obese patients. Insulin resistance impacts the pathogenesis of non-alcoholic fatty liver disease and may potentiate the progression of non-alcoholic steatohepatits and fibrosis. This study investigates the impact of leptin and adiponectin in morbidly obese diabetic and non-diabetic patients with regards to histopathological hepatic changes. Methods: Twenty morbidly… Continue Reading

Hepatic Iron Overload in Patients Undergoing Rygb
BACKGROUND: The most common cause of hepatic iron overload is a genetic mutation (C282Y) that causes an increase in serum transferrin saturation and ferritin levels. Abnormalities in iron metabolism as well as nonalcoholic steatosis are known conditions associated with obesity. The purpose of this study was to analyze the hepatic DNA of morbidly obese patients… Continue Reading

High Failure Rate After Laparoscopic Adjustable Gastric Banding (lagb): Five Year Follow Up.
Introduction: LAGB is a technique increasingly used in USA. The aim of this study was to analyze the 5 year outcome in terms of weight loss and complications.Methods and patients: We reviewed our prospective electronic database for all patients undergoing LAGB between 2002 and 2007. We assessed weight progression, complication and reoperation.Results: We performed 199… Continue Reading

High Visceral Adipose Volume Impairs Beta-cell Function and May Influence Surgical Options
BACKGROUND: The mechanism for type-2 diabetes (T2DM) resolution following bariatric surgery is unknown, but is typically more robust for malabsorptive procedures (roux-en-Y gastric bypass, RYGB) than for restrictive procedures (laparoscopic gastric banding, LGB). We hypothesize that high visceral volume is a predictor of pre- or frank diabetes and surgeries that rapidly deplete visceral adipose stores… Continue Reading

Hospital Colectomy Volume As a Surrogate for Advanced Laparoscopy
Although laparoscopic colectomy has been reported to have favorable outcomes compared to open colectomy, it has yet to gain widespread acceptance in the United States. We sought to investigate whether hospital volume for colectomy was an important factor to predict the likelihood of having colectomy performed laparoscopically.Methods: Using the Nationwide Inpatient Sample (NIS) from 1998… Continue Reading

How Do Nurses and Physicians Learn Gastrointestinal Endoscopy: Assessment of Learning Curves Using a High-fidelity Virtual Reality Simulator
Background:Recently, it has been suggested that nurses can perform diagnostic endoscopic procedures, which traditionally have been a physician’s responsibility. The existing studies concerning quality of sigmoidoscopy performed by nurses are small, used assessment tools with insufficient validation and to date there is very little knowledge of the learning curve patterns for physicians and nurses. The… Continue Reading

Human Monocyte Activation By Biologic and Biodegradable Meshes in Vitro
INTRODUCTION: We hypothesize that various biologic and biodegradable meshes (BM) differentially induce macrophage (MØ) activation in vitro. Inflammation and wound healing play critical roles in the integration of biologic and biodegradable meshes (BM) at the sites of hernia repair. Macrophages (MØ) are the key cells controlling inflammation and wound healing. Interleukin-1beta (IL-1b), IL-6, and IL-8… Continue Reading
