Excess skin problems among adolescents after bariatric surgery

BACKGROUND: Bariatric surgery results in significant and durable weight loss and improved health in severely obese adolescents. An important adverse consequence of the massive weight loss after bariatric surgery is excess skin and soft tissue. The prevalence and clinical characteristics of excess-skin related symptoms have been described in adults undergoing bariatric surgery but not in adolescents. While the higher skin elasticity of adolescents may result in fewer excess skin problems compared to adults, this hypothesis remains untested. The purpose of the present study was to describe the natural history of excess skin and its associated complications among severely obese adolescents undergoing bariatric surgery. METHODS: We evaluated data from the Teen-Longitudinal Assessment of Bariatric Surgery (Teen-LABS) cohort, a prospective, multi-institutional study of adolescents (13-19 years) undergoing bariatric surgery. Abdominal pannus severity (graded 0-5) and excess skin symptoms were evaluated pre-operatively and for the first five years after bariatric surgery. RESULTS: Among the 217 study participants, 198 (90%) had an abdominal pannus and 16 (7%) reported pannus related symptoms at the time of bariatric surgery. Preoperative symptoms included intertriginous infections (n=12, 75%), recurrent cellulitis (n=5, 31%), and superficial cutaneous ulcerations (n=1, 6%). Participants with a higher pannus grade pre-operatively experienced both a greater reduction in pannus severity (p
