The aim of this study is to assess that the sleeve gastrectomy can improve the risk benefit than the gastric bypass

In the obese patient population, the frequency of patients presenting a severe morbid obesity (40 >= BMI <= 50), a super obesity (BMI >50), a super super obesity (BMI>60), and obese patients (BMI>35) with a failure of gastric banding is constantly increasing. In these patients, the surgery risk is proportionate to the weight and / or gastric surgery records.

This risk is high, in bariatric surgery, for gastric bypass procedure. This justifies the evaluation of new procedure to reduce the morbidity allowing the reduction of morbid /mortality associated with the intervention.

Inclusion Criteria:

• Patient aged from 18 to 60 years old

• Patient having given his consent to the use of data from the project

  • A super super obesity BMI> 60
  • Obese patient in failure following the installation of a gastric banding with BMI> 35
  • obese patient 35>BMI>40 with a comorbidity

• Preliminary agreement during the consultation of a psychiatrist / psychologist
