Brief Summary

The management of obesity is based on a multidisciplinary approach and justifies the use of surgery in patients with the most severe forms. Surgery for obesity or bariatric surgery generally allows rapid and significant weight loss however it is associated with significant risks, and its long-term results remain heterogeneous and unpredictable. Long-term data will clarify the role of different types of bariatric surgery in surgical strategy, improve patient information and identify predictors of failure in order to provide personalised and tailored surgery for each candidate .
