Anatomical Measurements of the Gastric Cardia in Obese Patients
Background: Currently, surgeons may implant three different types of bands within the LapBand system. However, there is little data to guide the selection process. This study aims to determine the relationship between a patient’s body mass index (BMI), height, and weight and the anatomical measurements of the gastric cardia in morbidly obese patients undergoing LapBand… Continue Reading

The VAD-BAND, a Promising New Technique for Morbidly Obese Potential Cardiac Transplant Candidates
INTRODUCTION:Morbid obesity remains a strong risk factor limiting cardiac transplantation. Furthermore, numerous cardiac transplant databases have demonstrated that morbidly obese transplant recipients have nearly twice the 5-year mortality of normal-weight or overweight recipients. Hence, many morbidly obese transplant patients require ventricular assist devices to bridge them until they have lost sufficient weight to be considered… Continue Reading

Defining Differences among those who Succeed in Compared to those who Fail to Lose Significant Excessive Weight after Bariatric Surgery
Background: Gastric bypass and adjustable gastric banding are currently the most commonly performed weight loss surgeries. The results are encouraging for most patients; however, even among surgeons that perform hundreds of these procedures, some of their patients do better than others. This article has set out to define differences among those that succeed compared to… Continue Reading

Utility of Drainage Catheters for Gastrojejunal Leaks After Laparoscopic Roux-en-Y Gastric Bypass: A Retrospective Review of 434 Cases
BACKGROUND: A leak at the gastrojejunal anastomosis (GJ) is a well recognized and occasionally fatal complication of obesity surgery. Closed suction drains have been routinely placed in the region of the GJ at the time of laparoscopic Roux-en-Y gastric bypass (LRYGBP) in order to aid in the recognition and treatment of such leaks. However, drains… Continue Reading

Prospective analysis of the resolution of asthma in laparoscopic gastric bypass patients
Background: A dose dependent relationship between obesity and asthma has been reported in several epidemiologic studies. It has been proposed that interventions targeting obesity may reduce the incidence of asthma. We hypothesize that surgically induced weight loss will decrease the prevalence of asthma in a large group of bariatric patients. Methods: We analyzed data on… Continue Reading

Vagal Blocking for Obesity Control (vbloc) : Interim Six Month Results in an Ongoing Trial Using a Second Generation System
BACKGROUND: A new therapy (VBLOC) that intermittently blocks both vagi near the esophagogastric junction using high-frequency electrical algorithms has been reported to lower excess weight 14.2 (+/-) 2.2% in obese subjects as part of an earlier 6 month feasibility trial. The therapy is delivered by laparoscopically implanted electrodes. The proposed mechanisms for weight loss are… Continue Reading

Quality of life significantly improves after laparoscopic gastric bypass
Introduction:The Moorehead-Ardelt Quality of Life Questionnaire (M-A QoLQ) has been validated as a reliable tool in assessing quality of life issues in the obese population. We compared the quality of life data gathered prior to and 1 year following laparoscopic bariatric bypass surgery using the M-A QoLQ on selected outcomes including self-esteem, physical, social, work… Continue Reading

Natural Orifice Surgery: Initial US Experience Utilizing the StomaphyX™ Device to Reduce Gastric Pouches after Roux-en-Y Gastric Bypass
Purpose: To evaluate the effects of a new natural orifice surgical device to reduce gastric pouches after Roux-en-Y gastric bypass surgery. Methods: The StomaphyX™ device is a sterile, single-use device that is Food and Drug Administration (FDA) cleared for use in endoluminal trans-oral tissue approximation and ligation in the gastrointestinal (GI) tract. We proposed that… Continue Reading

Single center bariatric surgery experience with an optical access trocar in an uninsufflated abdomen and a critical review of minimally invasive peritoneal access techniques
Background:The Visiport is a widely-used bladed optical access device that provides convenient, safe peritoneal entry. We use this device as our primary method of entry and insufflation in bariatric surgery and provide an overview of our cumulative experience. In addition, we provide a comprehensive analysis of the literature to analyze all methods of peritoneal access… Continue Reading

Mesenteric Defect Closure and Prevention of Internal Herniation Following Laparoscopic Roux-en-Y Gastric Bypass
Background: Internal herniation is a dangerous complication following laparoscopic roux-en-y gastric bypass (LRYGB). Available studies have shown no clear benefit to operative closure of the jejunal mesenteric defect at the time of LRYGB.Objective: To analyze the impact of mesenteric defect closure on the incidence of internal herniation following LRYGB.Methods: We performed a retrospective study of… Continue Reading

Repair of Ventral Hernias with Prosthetic Mesh During Laparoscopic Gastric Bypass May Be Safe
Background: Deferring the repair of a ventral hernia found at the time of an antecolic laparoscopic gastric bypass (LGB) increases the incidence of bowel obstruction. However, the optimal repair technique has not been established. The use of prosthetic mesh has been shown to decrease the recurrence of ventral hernias compared to primary closure, yet the… Continue Reading

Perforated Marginal Ulcers after Laparoscopic Gastric Bypass
Introduction: A perforated marginal ulcer (PMU) following laparoscopic Roux-en-y gastric bypass (LRYGB) is a potentially serious complication, but the incidence and etiology has rarely been investigated. We therefore performed a retrospective review of all patients undergoing LRYGB at our center to determine our incidence of perforated marginal ulcer and if any causative factors could be… Continue Reading

Laparoscopic Gastric Bypass Does Not Necessarily Increase the Propensity to Develop Internal Hernias
Background: Although laparoscopic Roux en Y gastric bypass (LGB) has been proven to have numerous advantages over the open technique, internal hernia formation has been cited as a common and life-threatening complication associated more frequently with the laparoscopic technique.Methods: A review of all patients who underwent a LGB between 2003 and 2007 by a single… Continue Reading

Low Complication Rates Following Laparoscopic Gastric Bypass. a Report from the Bariatric Surgery Center of Excellence.
Introduction: Bariatric surgery remains the only modality to provide morbidly obese patients with a significant and sustained weight loss. Laparoscopic Roux-en-Y Gastric Bypass (LRGB) has become the gold standard of bariatric procedures. However significant but variable complication rates following laparoscopic gastric bypass were reported. Materials and Methods: We present our experience with 434 consecutive patients… Continue Reading

Comparative Weight Loss Analysis of Laparoscopic Gastric Bypass and Adjustable Gastric Band
Introduction: Comparative weight loss analysis between the gastric bypass (GB) and the adjustable gastric bypass (AGB) is difficult due to the need for long-term follow-up the need to control for potential confounders (i.e. initial BMI).Methods: Longitudinal mixed-effects models were used to analyze weight loss after either the GB or AGB. The multivariable analysis included controls… Continue Reading
