Filter by:This is a prospective case series study; all morbidly obese patients that need surgical management in Royal Alexandra Hospital will be provided 3 surgical options: Laparoscopic Sleeve Gastrectomy (LSG), laparoscopic Roux-en-Y gastric bypass (LR-en-Y), and laparoscopic gastric banding (LGB), safety and effectiveness will be compared among the 3 groups. The outcome measures will be percentage of excess weight loss, BMI, operative time, hospital stays, complications and improvement of comorbidities.
Executive Summary Aims and Hypotheses of the Study: The aim of the study will be to evaluate the safety, effectiveness and early outcome of the StomaphyX procedure for reducing the enlarged gastric pouch and stoma in post-bariatric patients. The study will test a hypothesis that the StomaphyX procedure will be effective in promoting the loss of regained weight, reducing the risk for comorbidities and improving patients' quality of life. Type of Study: Prospective non-randomized Study Duration: 12 months Number of Patients: 20 Inclusion Criteria: 18-70 years of age, BMI ≥ 35, ≥ 2 years after primary Roux-en-Y gastric bypass with evidence of enlarged gastric pouch volume or enlarged stoma diameter of ≥ 20 mm via endoscopy or fluoroscopy. Pts also demonstrate a weight regain of 15% of excess body weight loss. Exclusion Criteria: Esophageal stricture, or any anatomic conditions that preclude passage of transoral endoluminal instruments, has another causal factor for weight regain other than stoma or pouch dilatation, portal hypertension, coagulation disorders or chronic use of anticoagulants, any active medical condition that would preclude the patient from completing the study or would result in an unreasonable risk to the patient. Intervention Treatment: Creation of multiple full-thickness plications within the gastric pouch using the StomaphyX device (EndoGastric Solutions, Inc., Redmond, WA, USA) Evaluation Criteria Primary Outcome: Change in body weight at 6 and 12 months Secondary Outcome: Gastric pouch volume assessment, stoma diameter determination, quality of life scores, waist circumference, co-morbidity resolution Effectiveness and Safety Assessment Clinical: Weight, height, waist circumference quality of life questionnaires (Impact of Weight QOL-Lite, Eating and Weight Patterns, Three-factor Eating, Emotional Eating Scale, GI QoL, GSRS and/or PGWB) Anatomical: Upper GI endoscopy, computed tomography or barium radiography Biochemical: Blood and urine tests (glucose, cholesterol, triglyceride, HDL, LDL, uric acid) Safety: Adverse events, complications, co-morbidities, hospital stay
The purpose of this research is to further study the effect weight loss after gastric bypass surgery has on the heart and blood pressure and on how the body uses or metabolizes the sugars, fats and proteins we eat. Additionally, the researchers want to study fat tissue for gene patterns which may be responsible for where we carry fat on our bodies, as well as look carefully at a possible link between adipose tissue and insulin resistance. The researchers also want to evaluate the liver for the presence of fatty liver, which is common in people with obesity and is associated with insulin resistance, as well as study the liver for gene patterns which may be associated with non-alcoholic liver disease. Evaluating cardiovascular function and endocrine function before and after gastric bypass surgery, as well as studying adipose and liver tissue may help us understand the link between obesity, insulin resistance, fatty liver disease, high blood pressure and health problems such as diabetes and heart disease. Consequently, this may help in the future by identifying those who will benefit most from gastric bypass surgery.
This trial asks the question: do people of much greater than average body weight need more of a drug called oseltamivir than current recommendations suggest. Oseltamivir is a drug given to people who have influenza, and currently is also being used to fight the new H1N1 influenza. Some people of larger than average body weight require larger amounts of drugs to see the same effects as others of an average body weight. No studies have ever been conducted looking at the possibility of oseltamivir being one of those drugs. Our Study's hypothesis states that those of an above average body weight will have different amounts of drug in their blood than those of people of normal body weight if they are given the normal amount prescribed for influenza. Our study will give oseltamivir to twenty people for 7 days. Half of the people will be of normal body weight and the others will be of a much higher than normal body weight. Using blood samples the investigators will determine if the amounts of oseltamivir are significantly lower in the blood of patients in the above normal body weight group.
This is a randomized controlled study in which morbidly obese patients undergoing bariatric surgery will be recruited in the preoperative clinic. Patients will be randomized into 2 groups to receive oxygen with Boussignac TM continuous positive airway pressure (CPAP) or conventional Venturi mask postoperatively immediately after extubation. The objective of the study is to examine if Boussignac TM CPAP results in improved oxygenation versus Venturi face mask when it is applied immediately after extubation in morbidly obese patients post bariatric surgery.
The purpose of this study is to evaluate the results patients are obtaining with the Realize™ Adjustable Gastric Band-C during the first 24 months after surgery.
The investigators wish to study the effects of three forms of bariatric surgery: Roux-en-Y gastric bypass, Sleeve Gastrectomy, and Gastric Banding. The surgery is not part of the clinical trial. If your insurance does not cover the procedure, then you are responsible for payment of the surgical process. We are doing pre and post surgery testing to provide a better understanding of the effect of bariatric surgery-induced weight loss on metabolic function.
The purpose of this protocol is to determine how band fill volumes that are based on intraband pressure readings can influence the comfortability of the band and to compare weight loss with this methodology to weight loss with the conventional approach recommended in existing product labeling.
The hypothesis of this study was that gastric bypass (GBP) ameliorates gastroesophageal reflux disease (GERD) in morbidly obese patients.
The purpose of this study is to collect additional safety, performance and effectiveness data of the Easyband gastric band medical device in the treatment of morbid obesity in 4 European countries where the device is a CE marked approved product.
