About this trial

While bariatric surgery is established as a safe and effective alternative with well-defined risks for severely obese adults, little has been published on its use in children.

There are many unresolved questions concerning the long-term metabolic and psychological consequences of bariatric surgery in adolescents, and the difference with the adult population. The appropriate timing for bariatric surgery in young people, and the predictors of success and safety still need to be determined.

The aim of this long-term prospective study is therefore to establish the safety and efficacy profile of surgical procedures and to clarify whether reductions in morbidity and mortality outweigh the risks of serious surgical complications and lifelong nutritional deficiencies.
