研究概览
简要总结
The purpose of this study is to determine whether the Swedish Adjustable Gastric Band (SAGB) is safe, and effective in achieving weight loss in patients with Morbid Obesity.
详细描述
Surgical treatment of morbidly obese patients is considered a reasonable option for achieving weight loss when more conservative measures, such as diet and exercise have failed. Not only can weight loss be achieved, but also reduction / resolution of a patient's co-morbidities associated with excess weight. Adjustable gastric banding provides a less invasive, reversible bariatric surgery option. The SAGB has been commercially available outside the United States for this indication since 1996. Commercial availability has led to extensive literature supporting the safety and effectiveness of the SAGB. Given the available literature, a prospective, single arm, multicenter, study in a heterogeneous population of morbidly obese subjects in the U.S. is being conducted.

- •100 lbs. overweight or 1.5 times ideal weight;
- •Documented failure of conservative, non-surgical means of weight reduction within one year prior to the Screening Visit, including failure of supervised diet, exercise and or behavior modification programs, and pharmacologic therapy;

- •Able to commit to long-term follow-up, including band adjustment visits:
- •Living within the contiguous U.S. and is within a 100 mile radius of the study center;
- •Absence of significant psychopathology that could limit the subject's ability to understand the procedure, comply with medical, surgical, and/or behavioral recommendations, as documented during screening assessment;
- •Agrees to refrain from any type of reconstructive surgery that would affect body weight such as abdominal lipoplasty or liposuction, mammoplasty, or removal of excess skin for the follow-up period following SAGB placement; and
- •Candidate for surgical weight loss intervention (i.e., meets accepted health criteria for major surgery).
排除标准
