Bariatric surgery in adolescents is still under debate. Literature about the long-term impact of laparoscopic sleeve gastrectomy (LSG) on adolescents’ obesity and associated morbidities is scarce. It is unknown if LSG shows better long-term results in the adolescent or adult group.


To compare the long-term effectiveness of LSG on obesity and associated comorbidities between adolescents and adults.


This retrospective study analyzed all patients with morbid obesity who underwent LSG in (2011–2012) and were followed for up to 5 years. Patients were divided into two groups: adolescents and adults. Data were compared between the two groups.


LSG was performed in 139 adults and 91 adolescents. The mean ages of the adults and adolescents were 37.4 ± 11.4 and 17 ± 1.5 years, respectively. The preoperative body mass index values of the adults and adolescents were 48.4 ± 8.7 and 47.6 ± 7.5 kg/m2, respectively (P = 0.95). At 5 years, percentage of total weight loss increased in adolescents (to 35.8 ± 11.5%), while it remained almost the same in adults (26.3 ± 10%). At 1 year, about 68.2% of adults and 62.5% of adolescents were cured from diabetes though, 13% of diabetic adults had relapse at 5 years and none of the adolescents relapsed. Postoperative complications occurred in both groups.


LSG showed comparable weight loss results in adults and adolescents, with better results in adolescents. LSG is more effective in preventing and treating diabetes/prediabetes in the adolescent group.
