Abstract

Background: Obesity in pediatric and adolescent population has reached a universal pandemic. This study aimed to summarize the literature on the longest available outcome of bariatric surgery in morbidly obese adolescents. Methods: A systematic review was conducted to pool available data on the longest available (>3 years) weight loss and comorbidity resolution outcome in adolescent bariatric surgery. Results: A total of 14 studies reporting the result of bariatric surgery after 3 years in 950 morbidly obese adolescents were included. Preoperative age and BMI ranged from 12 to 19 years and from 26 to 91 kg/m2, respectively. Females were the predominant gender (72.8%). Laparoscopic roux-en-Y gastric bypass (n = 453) and adjustable gastric banding (n = 265) were the most common bariatric procedure performed. The number of patients at the latest follow-up was 677 (range from 2 to 23 years). On average, patients lost 13.3 kg/m2 of their BMI. Among comorbidities, only diabetes mellitus resolved or improved dramatically. Of 108 readmissions, 91 led to reoperation. There was a weight regain < 5 kg/m2 between 5 and 6 years of follow-up. Removal, exchange, or conversion of the previous band constituted the majority of the revisional procedures. Three deaths were reported. No long-term data was obtainable on nutritional deficiency or growth status of adolescents who underwent a bariatric procedure. Conclusion: Although bariatric surgery is a safe and effective procedure in the treatment of adolescent morbid obesity, long-term data is scarce regarding its nutritional and developmental complication in this growing population of patients. © 2017, Springer Science+Business Media New York.
