Factors Associated With Weight Loss After Laparoscopic Adjustable Gastric Banding in Adolescents With Severe Obesity.

Abstract

The primary outcome was to identify somatic or psychosocial factors associated with success at 24 months after a laparoscopic adjustable gastric banding (LAGB) procedure in our cohort of adolescents with severe obesity. Secondary endpoints were to describe weight loss outcomes, comorbidity resolution, and complications. We have retrospectively reviewed medical records of patients who had LAGB placed between 2007 and 2017. Factors associated with success at 24 months after LAGB were researched, with success being defined as positive percentage of excess weight loss (%EWL) at 24 months. Forty-two adolescents underwent a LAGB procedure, the mean %EWL was 34.1% at 24 months, with improvement in most comorbidities and without major complications. Having lost weight before surgery was associated with success, whereas a high body mass index at surgery was associated with a higher risk of failure. No other factor was found to be associated with success. Comorbidities mostly improved 24 months after LAGB and no major complication occurred. Having lost weight before surgery was associated with a successful surgery, whereas a high body mass index at surgery increases the risk of failure.
