Arms Assigned Interventions
Active Comparator: 1
Sleeve gastrectomy
Procedure: Sleeve gastrectomy
Laparoscopic sleeve gastrectomy is a restrictive procedure for the treatment for morbid obesity
Other Name: SLEEVE
Active Comparator: 2
Gastric Bypass
Procedure: Gastric Bypass
Laparoscopic gastric bypass is a restrictive and difficult absorption procedure for the treatment of morbid obesity
Other Name: BYPASS

Detailed Description:

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.
