Safety and Functionality of a Novel Gastric Sensing and Electrical Stimulation Device to Treat T2DM Overweight Subjects
BackgroundGastric electrical stimulation represents a new paradigm for treating obesity and diabetes, since its mechanism of action is physiological rather than anatomical modification of the stomach.The following describes a feasibility study of an investigational device, the TANTALUSTM System, intended for use in obese and overweight subjects with type 2 diabetes. The TANTALUSTM System (Metacure (USA)… Continue Reading

RNY gastric bypass causes more weight loss but lap-band is associated with fewer complications at 2 year followup
Introduction: Roux-en-Y (RNY) gastric bypass surgery is the most common weight loss operation for morbid obesity in USA. Lap-band has gained popularity in the last few years and has become the second most common weight loss operation. The objective of this study is to evaluate the early results in terms of weight loss and complications… Continue Reading

Fewer Gastrojejunostomy Strictures and Marginal Ulcers with Absorbable Suture
BACKGROUND: The upsurge of gastric bypass procedures has been accompanied by an increase in anastomotic strictures and marginal ulcers. In the reported literature, the gastrojejunostomy strictures in 3-27% and ulcerates in 1-16% of cases. Several anastomotic techniques are used; however, no study has specifically addressed whether choice of reinforcing suture affects rates of stricture or… Continue Reading

Improvement in Glycemic Control by Gastric Electrical Stimulation (TANTALUS®) in Overweight Subjects with Type 2 Diabetes (T2DM)
Background: The TANTALUS System (MetaCure Ltd.) is a minimally invasive implantable gastric stimulation modality that does not exhibit malabsorptive or restrictive characteristics. The device applies GCM (Gastric Contractility Modulation) signals to the stomach Antrum. The signals are delivered in synchronization to the native electrical activity of the stomach during meals. Retrospective analysis of previous studies… Continue Reading

Laparoscopic Roux-en-Y Gastric Bypass vs. Laparoscopic Adjustable Gastric Banding: 30-day Morbidity and Mortality as Assessed by Prospective, Multi-center, Risk-Adjusted ACS-NSQIP Data
Background: Previous comparisons of open and laparoscopic Roux-en-Y gastric bypass (ORYGB, LRYGB), and laparoscopic adjustable gastric banding (LAGB) have been limited by a lack of unique CPT codes for LRYGB and LAGB. Specific codes have been available for LRYGB since 2005, and for LAGB since 2006. This study compares the short-term safety of these procedures,… Continue Reading

Outcome of laparoscopic placement of an adjustable gastric band for morbid obesity in patients with esophageal motility disorders
Background: Recent studies of laparoscopic adjustable gastric band (LAGB) placement demonstrate improvement of gastroesophageal reflux disease (GERD), but the long term results of LAGB for patients with esophageal motility disorders remains unknown. The risk of worsening pre-existing esophageal motility disorders must be balanced against the benefits of LAGB, specifically its efficacy with respect to weight… Continue Reading

Short Term Outcomes after Simultaneous Laparoscopic Adjustable Gastric Banding (LAGB) and Hiatal Hernia Repair (HHR)
Background: The presence of hiatal hernia has been considered a contraindication for LAGB, since more complications such as band slippage (BS) were advocated. Few data have been reported on simultaneous LAGB and HHR.Methods: Between 11/04 and 7/05 432 patients underwent LAGB. Patients with less than 3 months f/u were excluded (total group 417). Patients were… Continue Reading

Laparoscopic Ileal Interposition Associated to a Diverted Sleeve Gastrectomy Is an Effective Operation for the Treatment of Type 2 Diabetes Mellitus Patients with Bmi 21 – 29
Introduction: The objective of this study is to evaluate the clinical results of the laparoscopic interposition of a segment of ileum into the proximal duodenum associated to a sleeve gastrectomy (II-DSG) in order to treat patients with Type 2 Diabetes Mellitus (T2DM) and BMI 21-29.Methods: The laparoscopic procedure was performed in 69 patients. 22 were… Continue Reading

Does Liberal IV Fluid Administration Decrease Post-Op Nausea and Vomiting in the Bariatric Surgery Patient? a Double Blinded, Randomized Trial
IntroductionPost-operative nausea and vomiting (PONV) represents a serious and vexing problem after bariatric surgery. We hypothesized that liberal administration of IV fluid administration may influence PONV. Methods50 patients were recruited from a bariatric surgery clinic in an academic hospital. Patients were randomized to two groups of intra-operative IV fluid administration: Group A received 15ml/kg while… Continue Reading

Quality of life as determined by SF 36 health survey is significantly improved following laparoscopic gastric bypass. A prospective analysis of consecutive 300
Introduction: The short-form 36 (SF-36) health survey has proven to be a reliable tool when assessing the burden of disease on both physical and mental health. Moreover, it is widely used to assess the effects of various treatment options on the overall quality of life. Using the SF-36 questionnaire, our goal was to quantify the… Continue Reading

Laparoscopic Conversion of VBG to Roux-en-Y Gastric Bypass
IntroductionMorbid obesity has been on the rise in the United States. A decade ago, open vertical gastroplasty was a popular restrictive gastric surgery for weight reduction with a high failure rate. We report our experience in a single institution in converting vertical band gastroplasty (VBG) to roux en y gastric bypass (RYGB) laparoscopically. MethodsA prospective… Continue Reading

Is BMI greater then 60 a predictor of higher morbidity after a laparoscopic Roux en Y gastric bypass?
Background: It has been hypothesized that patients who are super-super morbidly obese, defined as having a Body Mass Index (BMI) of 60 or higher, have an increased rate of post-operative complications. As surgical techniques and operator experience with Roux en Y gastric bypass improved with time, the selection criteria have expanded to include the super-super… Continue Reading

Drain Amylase Levels in Roux-en-Y Gastric Bypass: What Is a Normal Value?
INTRODUCTION: Anastomotic leak from the gastrojejunostomy (GJ) is a serious complication after laparoscopic Roux-en-Y gastric bypass (LRYGB). Normal imaging and a benign abdominal exam does not exclude the presence of a leak. The effluent from a GJ leak is composed primarily of salivary secretions and thus should have a high amylase level. The measurement of… Continue Reading

Safety and Cost Effectiveness of Small Bowel Extraction Without Wound Protection in Laparoscopic Roux En Y Gastric Bypass
INTRODUCTION: Small bowel resection is often required during laparoscopic Roux-en-Y gastric bypass (LRYGB), either with a circular stapled anastomosis technique or resection of excess Roux overhang. An extraction bag is often used to remove the resected portion of bowel. However, an extraction bag may cause the specimen to "mushroom," necessitating a larger fascial defect, thus… Continue Reading
