Active clinical trials for "Obesity, Morbid"

This study investigates the chronic long-term health condition of obesity and its effect on neutrophil function and the inflammatory response

The goal of clinical trial is to evaluate the impact of use of health-connected devices and of an Internet-based Intensive follow-up on physical activity recovery during the 6-month period after bariatric surgery in obese patients.

The main aim of this study is to analyze and report the preliminary and intermediate term outcomes after laparoscopic revision Roux-en-Y gastric bypass surgery for weight recidivism. 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; and 3) Patient satisfaction and Health-Related Quality of Life "HR-QoL" measured by a standardized, non-validated subjective satisfaction questionnaire and the validated, disease-specific, Moorehead-Ardelt II QoL questionnaires, respectively; 4) Morbidity & Mortality including nutritional status and metabolic complications. Consequently, secondary objectives of this study are 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 assessing preliminary and intermediate results after the surgery under analysis. 2) To evaluate the metabolic and nutritional status by measurements of particular clinical and biochemical parameters. This research is in line with the most current provocative new ideas and recent high impact publications. To the best of our knowledge, this is the very first outcome study of revisional malabsorptive distal gastric bypass surgery by laparoscopy with diverse revisional strategies such as revisional gastroplasty, revisional Fobi-Capella, revisional Adjustable Gastric Band, conversion to distal, and conversion to very, very long limb gastric bypass. Previously, several studies have addressed conversion to malabsorptive gastric bypass after a failed primary proximal gastric bypass but none has addressed the failed distal gastric bypass nor the adequate balance between increasing restriction and malabsorption for decreasing the risk of protein-calorie malnutrition.

Bariatric surgery in the treatment of morbid obesity is associated with long-term weight-loss and decreased overall mortality. Long-term results have been reported for laparoscopic gastric bypass procedures but the long-term results of laparoscopic sleeve gastrectomy are yet unavailable. As sleeve gastrectomy is a rapid and less traumatic procedure with good short-term results of weight loss and resolution of comorbidities, the investigators initiated a prospective randomized two-center study comparing laparoscopic sleeve gastrectomy (LSG)with laparoscopic gastric bypass (LGB) in the treatment of morbid obesity. Study hypothesis: As sleeve gastrectomy is less traumatic, easier and faster to perform compared with gastric bypass,LSG could become the procedure of choice to treat morbid obesity if the long-term results of weight loss and resolution of comorbidities are comparable with laparoscopic gastric bypass.

After bariatric surgery , thromboembolics complications are major cause of mortality. However, in obese patients, thromboprophylaxia is a controversy. Fondaparinux' efficacy is superior to HBPM, and is a good treatment for this population. Pharmacokinetics information with Fondaparinux in this population are rare.

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.

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 Minimally Invasive Surgery Team (MIST) are establishing a separate research database to find out more about patient's undergoing minimally invasive surgery (laparoscopic , open and robot assisted) procedures at UCSD. The hope is that collection of this information will give physicians a better knowledge and understanding of the benefits of minimally invasive surgery and possibly assist physicians to better manage future patients.

This research is being done to evaluate the ability to obtain a liver sample using upper endoscopy rather than through a laparoscopic procedure. The investigators hypothesize that the endoscopic transoral route is as effective as the laparoscopic route.

The purpose of this study is to evaluate the LAP-BAND AP System in severely obese patients.
