Bariatric surgery has been increasingly performed in adolescents over the past decade. Consensus guidelines have been developed to help heath care teams select adolescent candidates for surgery. Reports of short-term outcomes in adolescents have demonstrated similar BMI reduction and safety as in the adult population. There are several issues specific to adolescents that require further consideration, including a lower age limit and BMI at surgery, the optimal choice of bariatric procedure, the potential for the development of disordered eating and weight recidivism after surgery, and the extent of psychological and developmental assessment prior to performing these procedures. With the ongoing increase in the number of adolescent bariatric surgeries performed, it will be essential for high-level evidence with long-term follow-up to be generated to help address these issues and guide health care teams caring for teens with obesity.Bariatric surgery was first performed in adolescents beginning in the late 1970s, and the number of procedures performed has progressively increased over time. Data from the Kids' Inpatient Database [1] suggest that the number of bariatric operations in children and adolescents in the U.S. has doubled from 771 in 2003 to 1,615 in 2009. The increase is likely due to increasing rates of adult bariatric surgery and the knowledge that nonsurgical treatments have a limited effect on children with severe obesity and that, without an effective intervention, the majority of obese adolescents will remain obese in adulthood [2].The most common types of bariatric operations performed in adolescents include Roux-en-Y gastric bypass (RYGB), laparoscopic adjustable gastric banding (LAGB), and sleeve gastrectomy (SG) ( fig. 1) [3]. RYGB is both a restrictive and a
