Answer

O'Brien et al found that in adolescents, laparoscopic adjustable gastric banding resulted in a greater percentage of patients achieving a loss of 50% of excess weight, compared with lifestyle intervention. [41] In a prospective, randomized controlled trial in 50 patients aged 14-18 years with a BMI higher than 35 kg/m2, 21 patients (84%) in the gastric banding and 3 (12%) in the group assigned to supervised lifestyle intervention lost more than 50% of excess weight, corrected for age. Overall, the mean changes in the gastric banding group were a weight loss of 34.6 kg, representing an excess weight loss of 78.8%, 12.7 BMI units, and a BMI z-score change from 2.39 to 1.32. [41] The mean losses in the lifestyle group were 3 kg, representing an excess weight loss of 13.2%, 1.3 BMI units , and a BMI z-score change from 2.41 to 2.26.
