Laparoscopic sleeve gastrectomy in severely obese adolescents: effects on metabolic profile

Objective: The objective was to conduct clinical and metabolic evaluations of obese adolescents before and after laparoscopic sleeve gastrectomy (LSG) (up to 24 months). Subjects and methods: This was designed as a retrospective, descriptive series of cases study, conducted in Instituto da Crianca, Sao Paulo, Brazil. Analysis of clinical and laboratory data from 22 obese adolescents between 14 and 19 years old submitted to LSG between 2007 and 2014. Patients had BMI > 40 kg/m(2) or BMI > 35 kg/m(2) with comorbidities. Anthropometric, clinical and laboratory assessments were performed: before surgery, 6, 12, 18, and 24 months after surgery. We assessed weight loss and metabolic changes up to 24 months after LSG. Results: The mean preoperative weight and BMI were 128.5 kg (SD = 23.1) and 46.5 kg/m(2) (SD = 7.4), respectively. There was an average weight loss of 34.5 kg in the first 12 months' post LSG, corresponding to a 60% excess weight loss (EWL), as well as an average reduction in BMI of 12.3 kg/m(2). However, after 24 months, the average EWL was 45%, corresponding to an average weight regain (WR) of 13.3 kg (15%) within two years. LSG improved dyslipidemia in 67.8% of patients, a significant remission of hepatic steatosis 47% and 37.7% systemic arterial hypertension; type 2 diabetes remission was complete. Conclusions: LSG proved to be a safe and effective procedure and seems to be the new hope for the obesity epidemic.
