The impact of parental bariatric surgery and patient age on laparoscopic sleeve gastrectomy outcomes in adolescents



Adolescent obesity is multifactorial, but parental history is the most significant risk factor. Laparoscopic sleeve gastrectomy (LSG) is part of the multidisciplinary approach to adolescent weight loss.


We aimed to evaluate the effects of parental history of bariatric surgery, as well as age at time of operation, on adolescents who underwent LSG at our institution.


We performed a retrospective review of patients, aged 10 to 19 years, who underwent LSG from January 2010 to December 2019. The adolescent bariatric surgical dataset maintained by our group was used to obtain patient demographics, weight, body mass index (BMI), and parental history of bariatric surgery.


Among 328 patients, 76 (23.2%) had parents who had previously undergone bariatric surgery. These patients were significantly heavier by weight (p = 0.012) at the time of operation but had no difference in postoperative weight loss. When all patients were compared by age at operation (< 16 years, n = 102, ≥ 16 years, n = 226), there were few differences in outcomes.


LSG is an effective approach to surgical weight loss in adolescents. Patient age should not be a barrier to weight loss surgery, especially among patients with a parental history of obesity. By intervening at a younger age, the metabolic sequelae of obesity may be reduced.
