Background: Adolescent obesity has been steadily increasing all over the developed world for the past several decades. Bariatric surgery in morbid obese adolescents is gaining popularity. The main surgical technique that is used on adolescents in Israel is a gastric sleeve.
Aims: To study clinical and laboratory outcomes of adolescent patients 1 year after they underwent bariatric surgery.
Methods: Anthropometric, clinical and laboratory data were obtained from all patients ages 1319 years who had bariatric surgery in the years 20102015 in Edmond and Lily Safra Childrens hospital at Sheba Medical Center before and after the surgery.
Results: 27 adolescents (16 females) underwent bariatric surgery. Their mean age was 16.9±1.5 (range 13.718.60, weight 129±16 kg, BMI 46.6±5.8 kg/m2, BMI-z-score 2.8±0.27. Seven adolescents had obstructive sleep apnea, two had pseudo tumor cerebri, three had hypertension, two had type 2 diabetes, 13 had fatty liver in ultrasound and four had elevated liver enzymes. BMI changes throughout the first year of follow-up are presented in Figure 1. There was a significant weight reduction 3 months after the surgery, BMI 40.3±7.1 kg/m2 (P<0.001), Most of the weight loss occurred during the first 6 months. Thereafter there was no significant change. 1 year after the surgery, only 14 adolescents continued to come for follow-up. Two of them gained weight and were re-scheduled for operation, two adolescents developed eating disorder requiring referral to eating disorder clinic. four patients developed gall stones requiring cholecystectomy. One was hospitalized in rehabilitation because of paralysis secondary to severe vitamin deficiency.
Conclusions: Despite significant weight loss, bariatric surgery in adolescents is associated with significant long-term morbidity.
