Safety and Effectiveness Study of The Swedish Adjustable Gastric Band (SAGB) in the Treatment of Morbid Obesity

3 augustus 2015 bijgewerkt door: Ethicon Endo-Surgery

A Single-Arm, Multi-Center Study of the Safety and Effectiveness of The Swedish Adjustable Gastric Band (SAGB) in the Treatment of Morbid Obesity

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.

Gedetailleerde beschrijving

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.

  • Five year history of morbid obesity;
  • Body Mass Index (BMI) >40 kg/m2 and <55 kg/m2, or BMI >35 kg/m2 and <40 kg/m2 with one or more significant medical conditions related to obesity (co-morbid conditions of type 2 diabetes, hyperlipidemia, obstructive sleep apnea, hypertension, metabolic syndrome, or osteoarthritis of the hip or knee) for which the subject is being treated, and which are generally expected to be improved, reversed, or resolved by weight loss.
  • 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).

Exclusion Criteria:

  • Women of childbearing potential who are not practicing an effective method of birth control or who are pregnant or lactating;
  • Previous malabsorptive or restrictive procedures performed for the treatment of obesity;
