A Study of the Laparoscopically-placed Adjustable Gastric Band for the Management of Obesity in Adolescent Patients

University of Texas Southwestern Medical Center16 enrolled

Overview

This is a prospective, non-randomized, single center study of a laparoscopically placed, adjustable gastric band medical device for the treatment of adolescent obesity.

Study population We plan to enroll 30 subjects between the ages of 14 and 17 years with the LAP-BAND®. The inclusion criteria are in accordance with recent evidence-based indications for the surgical management of severe obesity in the pediatric population (Pratt, Lenders et al. 2009). The enrollees will be children who have a body-mass index in the 99th percentile, corresponding to a BMI\>= 35 kg/m2, and who exhibit significant comorbidities. This sample size will provide over 90% power to detect a 15% change in body mass index with a standard deviation of 6, two-tailed alpha of 0.05, and allow for 20% loss to follow-up, using a paired design.

Outcomes

Primary Outcomes

Change in Body Mass Index Z-score

Measure of relative weight adjusted for child age and sex. The Z-score indicates the number of standard deviations away from the mean. A Z-score of 0 is equal to the mean. Negative numbers indicate values lower than the mean and positive numbers indicate values higher than the mean.

Time frame: 12 months post operation
