Severe obesity (SO), defined as BMI≥95th percentile, has increased worldwide among adolescents. American studies estimated that 1.3-2.8% of 12-19-year-old individuals have a BMI >40 kg/m2 or a BMI >35 kg/m2 with at least one serious co-morbidity. The immediate and long-term risks associated with SO in adolescents include cardiovascular and metabolic diseases, obstructive sleep apnoea and nonalcoholic fatty liver disease. However, the results of sleeve gastrectomy in adolescents are still uncertain.

Objective and hypotheses: Investigators aimed to assess the long-term safety, efficacy, and cardiovascular risk changes of laparoscopic sleeve gastrectomy in adolescents with SO.

Method: Longitudinal retrospective study of 22 adolescents with SO who underwent laparoscopic sleeve gastrectomy. Clinical and metabolic variables immediately before surgery and after 6, 12, 18 and 24 months were assessed.

Inclusion Criteria:

• ages of 14 and 19
• submitted to LSG between 2007 and 2014.
• attended the child obesity clinic of the pediatric endocrinology department of the Instituto da Criança da Universidade de São Paulo (Children's Institute of University of São Paulo).
• received clinical and pharmacological treatment for at least 6 months before surgery and were followed by a multidisciplinary team including a pediatric endocrinologist, a nutritionist, a psychologist and a physical educator.
• BMI > 40 kg/m2 or BMI > 35 kg/m2 with comorbidities and failed to achieve significant weight loss (10% of initial weight at 6 months) through clinical treatment.
• Both the patients and their guardians were informed about the risks and benefits of surgery and provided informed consent.

Exclusion Criteria:

• it was a retrospective study
