  • Significant movement limitations
  • Use of weight-promoting or weight-reduction drugs during study period
  • Severe eating disorders
  • Uncontrolled depression or psychoses
  • Ongoing severe complication resulting from initial RYGB or other condition that in the investigators' assessment would make the patient an unsuitable candidate for the study procedure

Outcomes

Primary Outcome Measures

Weight Loss (%)
Percent Weight Loss is computed as [(Baseline weight - 6 mo. weight) / Baseline weight] * 100

Secondary Outcome Measures

Subjects Achieving 15% Excess Weight Loss (EWL)
%Excess Weight Loss (%EWL) is computed as:[(Weight at Baseline - Weight at 6 months)/(Weight at Baseline - Ideal Weight at BMI of 25)]*100.
Subjects Achieving Weight Stabilization at 6 Months
Weight is stabilized if 6 month weight is +/- 2% from baseline weight.
Subjects Achieving 20% Excess Weight Loss at 6 Months
%Excess Weight Loss (%EWL) is computed as: [(Weight at Baseline - Weight at 6 months)/(Weight at Baseline - Ideal Weight at BMI of 25)]*100

5. Study Description

Brief Summary
It is estimated that up to 20% of patients who have Roux-en-Y Gastric Bypass (RYGB) surgery will not meet their weight loss goal, or may even regain some of the weight they initially lost. One possible explanation is that the opening between the stomach pouch and the intestine becomes stretched. If this opening becomes too wide, food may be able to pass from the stomach to the intestine too quickly - causing patients to feel less full after eating. For some patients, doctors may recommend additional invasive surgery to tighten the opening between the stomach pouch and the small intestine. Although this may help patients resume their weight loss, the risk of complications during a second surgical procedure is significantly higher than the risk during the original gastric bypass. The purpose of this study is to evaluate an incisionless procedure for patients who have either had inadequate weight loss or have regained weight following gastric bypass. The procedure is designed to tighten the opening between the stomach pouch and the small intestine, which may slow down the passage of food to help patients feel full longer after eating.
