- Six patients (4 male) aged 14- 16 years (mean age 15.10) underwent
bariatric surgery. The mean preoperative body mass index (BMI) was 62.7
kg/m^2 and BMI SDS +4.4. Four patients had LRYGBP, one LAGB and one
had a LGS performed. The mean percentage of weight loss, as a percentage of
total body weight at 6 and 12 months, was 22 and 27%, respectively (Figure
5). Average absolute weight loss at the most recent follow-up was 54 kg.
Mean BMI at 12 months post=procedure was reported at 46.5 kg/m^2 - a mean
fall of 16.2 kg/m^2. The mean BMI SDS fell from +4.4 to +3.8 at 12 months
and +3.1 at 2 years.

Resolution of hypertension, improved attendance at school and no

Possibly the most recent data we have on outcomes on childhood bariatric
surgery is from the Teen-LABS 2016 report published in the New England
Journal of Medicine [124]. Teen-LABS is a prospective, multisite
observational study which enrolled patients 5 US sites, from February 28,
2007, through to December 30, 2011, with a final analysis cohort of 242. The
mean (SD) age of participants was 17.1 (1.6) years and the median BMI was
50.5. Laparoscopic Roux-en-Y gastric bypass, LSG and LAGB were
performed in 66%, 28%, and 6% of patients, respectively. Three years after the
procedure, the mean weight had decreased by 27% (95% confidence interval
[CI], 25 to 29) in the total cohort, by 28% (95% CI, 25 to 30) among
participants who had gastric bypass, and by 26% (95% CI, 22 to 30) in those
