Further study details as provided by GI Dynamics:

Primary Outcome Measures:
  • % of Excess Weight Loss (EWL) [ Time Frame: 12 months ]

    Percent excess weight loss (EWL) was calculated using Body Mass Index (BMI25) method: BMI25=ideal weight in kg/(height in meters)2 Ideal weight in kg = 25 x (Height in meters2) Baseline Excess weight = total weight - ideal weight

    % EWL = (baseline excess weight - weight loss) x 100

Secondary Outcome Measures:
  • HbA1c Values at 12 Months [ Time Frame: 12 months ]

Enrollment: 22
Study Start Date: October 2008
Study Completion Date: December 2010
Primary Completion Date: March 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: EndoBarrier GI Liner
22 patients were implanted with the GI Liner for a 52-week duration. Assessments were performed during the 6 months post-explant period.
Device: GI Liner
Medical device placed endoscopically in the duodenum, nutritional counseling
Other Name: GI Endobarrier Liner

Detailed Description:
Patients with obesity are at significantly greater risk of developing complications such as pulmonary dysfunction, diabetes, hypertension, and other co-morbid risks. NIH panel recommendations state that even a 10% short-weight loss would greatly reduce these risks. GI Dynamics' GI Sleeve represents a viable alternative to other short-term pre-surgical weight loss methods. GI Sleeve is a device that can be implanted and removed through minimal invasive endoscopic techniques. This endoscopic procedure brings potential benefits to patients in that it is minimally invasive, efficacious, and allows patients to recover faster with less morbidity and mortality.
