Background: Medical weight loss options are rarely successful long term in young patients. Bariatric surgery has been shown to be safe and effective in this population. Methods: Patients ≤21 years old who had bariatric surgery at our institution between January 2009 and December 2013 were evaluated to determine the safety and efficacy of bariatric surgery in this population. The primary end point was excess weight loss (EWL). Secondary end points included surgical morbidity, improvement in obesity-related metabolic parameters, and subjective obesity-related symptoms at 1 year. Results: Fifty-four patients were identified who had a laparoscopic Roux-en-Y gastric bypass (LGBP) or laparoscopic sleeve gastrectomy (LSG). Fourteen patients were male (25.9 %), and 40 patients were female (74.1 %). Thirty-seven patients (68.5 %) underwent LGBP, and 17 patients (31.5 %) underwent LSG. Median follow-up was 13.3 months. The baseline BMI was 51.7 kg/m2 for the LGBP group and 51.0 kg/m2 for the LSG group. EWL was 35.2, 47.6, 62.4, 58.1, and 61.8 % for the LGBP group; 29.7, 44.7, 57.4, 60.3, and 59.0 % for the LSG group at 3, 6, 12, 24, and 36 months, respectively. Our complications included 1 anastomotic bleed, 1 postoperative stricture, and 1 patient who developed vitamin deficiency that manifested as a peripheral neuropathy in the LGBP group. LGBP was more successful than LSG in improving lipid panel parameters and HbA1c at 1 year, and it also seemed to offer better subjective improvement in obesity-related symptoms. Conclusions: LGBP and LSG seem to confer comparable weight loss benefit in patients ≤21 years old with acceptable surgical morbidity.
