Comparative results of gastric banding in adolescents and young adults.

Background/purpose: Obesity has become a major public health priority. Because of disappointing results obtained with dietary and medical programs, bariatric surgery has been offered to adolescents, although this practice remains controversial. Our aim was to evaluate laparoscopic adjustable gastric banding (LAGB) in adolescents at 2-year follow-up.

Material And Methods: This prospective study, from 2008 to 2013, compared results between adolescent patients and young adult controls. The LAGB technique and the follow-up program were similar. Weight loss and comorbid disease were analyzed.

Results: Thirty-six adolescents (mean age at surgery=16.7±1.3years) were operated on and compared to 53 young adults (mean age at surgery=21.7±1.9years). The mean weight and BMI at surgery were 124.4±20.7 and 43.9±5.5kg/m(2), respectively. Among the adolescents, none were diabetic or hypertensive. The mean glycated hemoglobin was 5.6±1.2%. In four cases (11%) dyslipidemia was observed. There was no significant difference between the two groups in terms of initial preoperative weight or BMI. The absolute BMI values at 6, 12 and 24months after surgery were comparable between adolescents and young adults: 38.7 vs 39.8, 36.0 vs 37.6 and 33.5 vs 36.1kg/m(2), respectively. The excess weight loss was higher in adolescents at 12 and 24months: 48.6 vs 37.6% (p=0.03); and 62.3 vs 45.5% (p=0.02). During this period, insulin resistance and dyslipidemia decreased similarly in both groups.

Conclusion: Provided there is careful selection of patients and a supportive multidisciplinary team, satisfying results can be obtained after LAGB in adolescents, comparable to those obtained in young adults at 2-year follow-up.
