When a subject is approved for surgery, he or she will meet with Bariatric Surgeon to discuss benefits and risks of each bariatric surgery. After the appropriate discussion with surgeon, the choice of procedure will be made by subject and legal guardian. For research purposes, we seek to monitor the progress of the patients enrolled in Yale's Adolescent Bariatric Surgery Clinic. Collecting pre and post long term operative data will allow us to describe this efficacy and potential complications that arise with RYGB vs LAGB.
