Filter by:The purpose of this study is to determine laparoscopic sleeve gastrectomy is a safer surgery than the gastric bypass, gives similar weight losses and that the safety of gastric in private pay patients versus insurance patients will be similar. This is a retrospective chart review of intervention charts.
The purpose of this study is to quantify the relative contribution of improved insulin sensitivity and improved insulin secretion to the glycaemic effect of bariatric surgery.
The UCLA Metabolic and Bariatric Surgery Program (adult program) and the UCLA Fit for Healthy Weight Program (adolescent program) are committed to the care of morbidly obese patients. This study is observational. The investigators plan to evaluate bariatric surgery outcomes using the BAROS National Database and also to evaluate quality of life pre- and post bariatric surgery. In addition, the investigators plan to enroll a subgroup of 10 reproductive-age women to evaluate: 1) pregnancy and offspring health, 2) long-term nutrition, 3) biomarkers/epigenome, and 4) body-composition/bone-density.
Periodic analyses of our extensive database with regards to different surgical procedures for severe obesity and different obesity co-morbidities will be of benefit to our severely obese patients as well as to others world-wide.
Laparoscopic adjustable gastric banding (LAGB) has been used worldwide to help selected morbidly obese adults to lose weight. The FDA has approved LAGB only for patients 18 years or older. Our hypothesis that LAGB can be used to assist selected adolescents between 14 and 17 years lose weight and that the procedure can be performed safely in this age group. We are also evaluating the effects of weight loss after LAGB on known comorbid conditions such as sleep apnea syndrome and insulin resistance, and also on psychological health.
Exercise training is proved to protect against premature cardiovascular mortality. Additionally there is evidence that relatively high exercise intensity may be an important factor for improving aerobic capacity and endothelial function in patients with post-infarction heart failure, metabolic syndrome, coronary artery disease, as well as in overweight and obese individuals. The aims of this study is to investigate if High-intensity exercise before a gastric bypass operation will decrease hospitalization days and complications after the gastric bypass.
Our aim is to complete a survey study of patients who have undergone Adjustable Gastric Band (AGB) surgery at the University of Washington Medical Center (UWMC) and expanded to other bariatric surgical sites outside the University of Washington (UW), which will obtain a HIPAA waiver and a letter of cooperation) between April 1, 2007 and July 1, 2008. (Please note the University of Washington team will not have access to the site's list of patients, only access to coded returned surveys sent back from patients). Patients will be identified by obtaining operative case lists from the Department of Surgery Quality Improvement Team who maintain monthly records of bariatric procedures performed. We will obtain patient contact information (address) and patients will be contacted by mail with the request that they complete both the Adjustable Gastric Band (AGB) Health Survey and a standard Quality of Life survey (EQ5D). The mailing will include an Information Statement, the AGB Survey, the EQ5D, and a stamped return envelope. As an incentive, a $2 bill will be sent along with the first mailing to cover the costs of completing and returning the surveys. Patients who do not return survey within 30 days will be mailed a second survey. Patients who do not return the second survey within 30 days will be mailed a third survey. Patients who do not return the third survey will not be re-contacted.
We propose to compare the standard of care with the use of a novel medical food in 6 bariatric surgery patients by measuring outcomes of body composition, quality of life, hair loss, muscle strength, resting energy expenditure, and biochemical parameters.
The main aim of this study is to analyze and report the intermediate term outcomes after laparoscopic revision Roux-en-Y gastric bypass (RYGB) surgery for failed and/or complicated Vertical Banded Gastroplasty (VBG). The foremost outcome measurements are 1) Fat loss mainly measured as weight loss and expressed as trends in BMI, %EWL, and/or %EBL. 2) Trend in Comorbidity status. 3) Subjective Satisfaction and Health-Related Quality of Life "HR-QoL" are measured by a standardized, non-validated satisfaction questionnaire and by a validated, disease-specific worldwide used HR-QoL questionnaire. 4) Morbidity & Mortality include nutritional status and metabolic complications. Consequently, secondary objectives of this study are the following. 1) To assess failure rate defined as percentage of excess weight loss < 50%, lowest BMI >35 for morbidly obese (MO) or >40 for superobese (SO), and/or lack of resolution/improvement of major comorbidities at the point in time when assessed at each postoperative year after the surgery under study. 2) To evaluate the metabolic and nutritional status by measurements of particular clinical and biochemical parameters.
The goal of this study is to describe the clinical presentation, indications, and operative treatment as well as assess the morbidity, mortality, and overall performance of revisional Roux-en-Y gastric bypass (RYGB) after either failed or functional antireflux surgery "ARS" in obese patients. With such information, we hope to determine which features might assist us in advancing our knowledge about Gastro-Esophageal Reflux Disease "GERD", the best option for primary ARS, and mechanisms of failure in the obese population as well as in identifying predictors of outcome after revisional surgery in this population.
