Clinico-functional Evaluation of GERD: Comparative Study of Vertical Sleeve Gastrectomy vs Roux-en-Y...

Gastroesophageal Reflux DiseaseMorbid Obesity

The hypothesis of this study is that surgical techniques primarily designed for weight loss, ameliorates gastroesophageal reflux disease (GERD) in morbidly obese patients. Therefore the present study intends to evaluate such impact on patients submitted to two of the most common techniques available, the Roux-en-Y Gastric Bypass and Vertical Sleeve Gastrectomy.

Comparison of Gastric Bypass and Sleeve Gastrectomy in Metabolic and Cardiovascular Indices

Morbid Obesity

Morbidly obese patients undergoing either Roux en Y gastric bypass or sleeve gastrectomy were examined preoperatively, 3, 6, and 12 months after surgery. On each occasion, anthropometric data were collected, resting metabolic rate was measured, and the patients underwent a panel of cardiovascular examinations (heart rate variability, baroreflex sensitivity, heart ultrasound). Following that, they consumed a test meal and completed visual analog scales for the subjective assessment of hunger and fullness every 30 minutes for 3 hours. At the same time points, blood samples were collected for the consequent measurement of glucose, insulin, lipids, and gastrointestinal hormones.

Weight Loss With Meal-Replacement Therapy in Teens

ObesitySevere1 more

This study seeks to examine whether meal-replacement therapy is able to enhance weight loss among teens with severe obesity. In addition, we are also interested in examining the degree of weight loss needed to improve important cardiometabolic risk factors among adolescents.

Effects of Dietary Intervention and Surgery on NAFLD (Non-Alcoholic Fatty Liver Disease)

Non-Alcoholic Fatty Liver DiseaseNon Alcoholic Fatty Liver3 more

Approximately 90% of people undergoing bariatric surgery have NAFLD, which is a condition where fat accumulates in the liver and can lead to inflammation and scarring. It mostly causes no symptoms, however, in the most advanced cases there is an increased risk of liver cancer or liver failure. NAFLD is currently managed by weight loss and treating associated diseases such as diabetes. No medicines have been licensed to directly treat it but bariatric surgery has been shown to be usually beneficial, although it is unknown whether some operations are better than others. It is also unclear whether this is due to general weight loss or other factors. This study will be conducted in a hospital setting and aims to determine what changes in liver fat and fat processing occur after pre-operative low calorie diet and the two most common types of bariatric surgery (Roux-en-Y Gastric Bypass and Sleeve Gastrectomy. Participants will have ten study visits, four of which may be combined with NHS appointments. Participants will undergo investigations including MRI scans to measure changes in NAFLD and DEXA scans to measure changes in fat and fat-free mass (FFM). Participants will also undergo mixed meal testing to which stable isotopes (deuterated water and 13c-palmitate) will be added to allow changes in fat processing to be detected. In addition to samples taken as part of NHS care, blood, urine, liver and fat (visceral and subcutaneous (abdominal and gluteal)) will be used for research. Visits will take place before and after low calorie diet and bariatric surgery.

Bariatric Surgery CandidateObesity1 more

This study aimed to evaluate Laparoscopic Sleeve Gastrectomy in the treatment of morbidly obese patients pre and post-operatively after 3 months, 6 months, and 1-year follow-up and assess the volumetric changes of the gastric reservoir 1 year after LSG using multi-slice computer tomography.

Determinants of Fat Malabsorption After Roux-en-Y Gastric Bypass

Severe Obesity

The purpose of this study is to determine whether or not the length of the biliopancreatic limb of the Roux-en-Y anastamosis plays a critical role in the development of malabsorption after gastric bypass for treatment of severe obesity.

Laparoscopic Adjustable Gastric Banding Versus Laparoscopic Sleeve Gastrectomy

Morbid Obesity

The investigators aim to determine the clinical and metabolic outcomes of two available bariatric restrictive procedures: laparoscopic adjustable gastric banding (LAP-BAND) and laparoscopic sleeve gastrectomy for the treatment of morbid obesity (BMI > 35 with comorbidities or BMI > 40) in VETERANS. The investigators hypothesize that the short and long term outcomes between laparoscopic adjustable gastric banding (LAP-BAND) and sleeve gastrectomy are similar in VETERANS.
