ABSTRACT
BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) is used to treat obesity in adults. Less is known about long-term results of the procedure in adolescents. OBJECTIVES: To evaluate LAGB 5-year outcomes in teenagers with severe obesity. SETTING: Children's hospital, USA. METHODS: Adolescents (14-18 years) underwent LAGB in an FDA-approved observational clinical trial. Outcomes including anthropometric measurements, comorbid conditions, complications, and band retention were collected through 60 months. RESULTS: One hundred thirty-seven subjects underwent LAGB (94 female, 43 male; 43% white, 37% Hispanic, 17% black; 4% other). Mean age and body mass index (BMI) pre-operatively were 17.0 + 1.2 years and 48.3 + 8.2 kg/m2, respectively. Comorbidities were present in 71%. Maximum weight loss occurred by 36 months (mean % excess weight loss (EWL) 40.6 + 35.2, mean % excess BMI loss (EBMIL) 41.6 + 34.9) and was maintained through 5 years for most subjects. There were no significant differences in weight loss by gender. Twenty-three (18%) of 127 adolescents reporting at 60 months achieved 50% excess weight loss. Postoperative heartburn and emesis occurred in 70% and 32%, respectively. Complications requiring additional surgery occurred 80 times in 63 patients. Thirty-three (26%) of 127 subjects contacted at 5 years had undergone band removal. CONCLUSION: In this study, fewer than 20% of adolescents with severe obesity lost > 50% of their excess weight following LAGB. Nearly 50% of patients required additional surgery. With reports of success following sleeve gastrectomy and gastric bypass, we believe that LAGB is not a preferred choice to treat adolescents with obesity.

BACKGROUND: Evidence supports weight loss surgery as an effective long-term weight reduction therapy in adults. METHODS: Few adolescent obesity surgery series report outcomes for laparoscopic gastric banding (LAGB). We studied a population of morbidly obese teenagers who underwent LAGB to evaluate its safety and effectiveness in this age group. Three hundred and six morbidly obese adolescent candidates for LAGB were screened. Enrollees were evaluated monthly by the nutritionist and the surgical team to monitor compliance with recommended changes in diet and exercise. Patients also underwent psychiatric and endocrine evaluations. Those who made good changes in eating and exercise habits over a 6-month period were offered LAGB. The setting was a university hospital in the United States. RESULTS: One hundred thirty-seven adolescent patients underwent LAGB. The mean weight gain between enrollment and LAGB was 4.7 kg. Mean preoperative weight, body mass index (BMI), and excess BMI were 136.1 kg, 48.3 kg/m2, and 23.6 kg/m2, respectively. Mean BMI at 6, 12, 18, 24, and 36 months was 43.8, 41.6, 41.5, 40.5, and 39.3. Excess BMI loss was 28.4%, 35.9%, and 41.1% at 1, 2, and 3 years postop. Co-morbid conditions improved or resolved with weight loss after LAGB. Thirty patients (22%) underwent one or more additional operations for complications. Twenty-seven patients (20%) converted to other weight loss procedures or had their bands removed. CONCLUSION: LAGB is a safe weight loss operation in adolescents. Morbidly obese adolescents can lose weight successfully and experience health improvement following LAGB, but the role of LAGB in the younger population requires long-term evaluation.
