Filter by:This study try to identify differences in cost, length of operation and results between two different bariatric surgical techniques, the laparoscopic Roux-en-Y gastric bypass and the Single anastomosis laparoscopic gastric bypass. The study will be conducted in a Spanish public health system hospital. The patients of the trial will have the preoperative studies, hospital treatment during the admission, postoperative treatment and follow up as any other patient included in the hospital bariatric surgery program. No new methods are applied other than randomly choose the surgical technique. Patients will be randomized in a 1:1 ratio to each group.
In this pre-post observational study, the investigators will enroll and follow a cohort of about 50 adults undergoing sleeve gastrectomy surgery for weight loss. Pre-operatively and at 6 and 12 months post-operatively, the investigators will use state-of-the-art metabolic and imaging techniques to evaluate calcium metabolism and skeletal health. Specific outcomes include intestinal calcium absorption capacity, bone mineral density (BMD) assessed by dual-energy X-ray absorptiometry (DXA) and quantitative computed tomography (QCT), and bone structure assessed by QCT and high-resolution peripheral QCT (HR-pQCT).

Sleeve gastrectomy is now the most commonly performed bariatric surgery. While many studies have evaluated factors that may minimize post-operative hemorrhage and staple-line leak, the investigators are unaware of any studies that compare outcomes between devices from the two main stapler manufacturers used in this surgery, Covidien and Ethicon. The purpose of this study is to compare intraoperative characteristics, such as time to create sleeve, intraoperative bleeding, and time needed to load each cartridge, and post-operative characteristics, such as any complication requiring readmission (leak or hemorrhage), further surgical intervention, and weight loss, between patients who underwent sleeve gastrectomy with Covidien devices and Ethicon devices. Currently the investigators predominantly use whatever device is cheaper, but cost should not be the primary decisive factor if one device is superior to the other. If one device has better clinical outcomes, it should be the preferred device regardless of cost. If neither proves superiority, the investigators can justify using cost to determine which device to use in patient care.
Increasing rates of highly malignant hepatocellular carcinoma (HCC) and biliary tract cancers (GBTC) observed in Western populations may be related to obesogenic lifestyle factors and their metabolic consequences, such as metabolic syndrome (MetS), inflammation and altered production of bile acids (BA). Such lifestyle behaviours may induce changes in the gut microflora which in turn affect BA profiles, increasing their carcinogenicity. Some elevated BA may be oncogenic in exposed liver, bile ducts and gall bladder. Vertical sleeve gastrectomy may change bile acid composition. The aims of this study are: 1. whether specific presurgical bila acid profiles are predictive of efficacy of vertical sleeve gastrectomy, reflective of liver function and metabolic dysfunction; 2. whether specific presurgical bile acid profiles are predictive of the efficacy of sleeve gastrectomy
Obesity affects more than 78 million adults in the United States and it is estimated that 35% of the US population is obese. Currently, more than 179,000 bariatric procedures are performed in the US each year with the majority of these surgeries using laparoscopic techniques. Surgeons often request deep neuromuscular blockade (NMB) during surgery, but there is no evidence that a deep NMB improves surgical conditions and that the surgeons can discriminate between a moderate and deep NMB. There is also evidence that maintaining low insufflation pressures during laparoscopic surgery may decrease postoperative pain. The goal of this prospective, randomized, assessor-blinded controlled trial is to test the hypothesis that deep NMB provides optimal surgical conditions during laparoscopic bariatric surgery in the morbidly obese patient. It will also determine if deep NMB allows the surgeon to utilize lower insufflation pressure and decreases postoperative pain requirements after laparoscopic bariatric surgery.
The purpose of this study is to evaluate the effect of prebiotic or synbiotic supplementation on inflammatory response and indicators of nutritional status in patients with morbid obesity. Study hypothesis: Supplementation of 12 g/day of fructooligosaccharides (prebiotic) or 12 g/day of fructooligosaccharides + strains of lactobacilli and bifidobacteria (synbiotic) during 30 days promotes reduction of plasma/serum levels of acute phase proteins, cytokines, metabolic and anthropometric parameters in individuals with BMI ≥ 40kg/m².
This is a long-term follow-up and interventional study in individuals who have been diagnosed with moderate to severe obesity with or without diabetes. The purpose of this study is to determine the effects of sleeve gastrectomy on weight and blood sugar control and underlying mechanisms by metabolomics, metagenomics, functional magnetic resonance imaging (fMRI) ,adipose tissue expression chip and etc.
Gastroesophageal reflux disease (GERD) is a frequently seen entity after sleeve gastrectomy. Management of GERD after sleeve is difficult given limited treatment modalities. Stretta is an endoscopic FDA approved device that improves symptoms of GERD, there is minimal information about its use on patients after sleeve. This registry will attempt to get information regarding the treatment of reflux using Stretta after sleeve gastrectomy.
The frequency of super-super obese who need immediate weight loss surgery is risen continuously. For those patients a prior-to-surgery conditioning therapy is mandatory to gain technical and physical operability. The exclusively well-established preliminary therapy so far was the intragastric balloon, which takes 7 months of treatment time. Due to life-threatening conditions of giant obese patients, who have been admitted to hospital, the investigators were forced to develop a more prompt acting conditioning therapy to bring those individuals in a short run to an improved and "fit-for-surgery" state. In such an impasse the investigators combine Liraglutide with its well-known weight-loss effect with a leucine-based amino acid infusion that is generally used for patients with liver insufficiency, in expectance of an additional weight loss and liver reduction effect.
