Overview
Brief Summary
Morbidly obesity (body mass index 40 kg/m²), the most serious, is more and more frequent. Cardiovascular diseases are the first cause of morbidity and mortality. An excess of TRL particles is one of the characteristics, represents a major cardiovascular risk factor. The overproduction of the intestinal TRL (which apoprotein B48 is the specific tracer) is recently recognized of insulin-resistance and the atherogenous role of these intestinal TRL has been shown. In front of this important overmortality, the bariatric surgery quickly developed. Three main procedures are performed: 2 based exclusively on the gastric restriction (the adjustable gastric banding and the sleeve gastrectomy) and one associating a malabsorption (the gastric bypass).
Detailed Description
It is a monocentric, prospective, comparative study. After identification of the eligible subjects, the kinetics (production and clearance rates) of the intestinal TRL will be performed in the hospital, using a stable isotope method (5,5,5-D3-L-Leucine), in 3 groups of obese patients (12 patients per surgery procedure), before and 6 months after the surgery

Outcomes
Primary Outcomes
to compare the differential effect of the 3 bariatric surgery procedures on the production rates of the intestinal TRL
Time Frame: 36 months
the 3 bariatric surgery procedures are: the adjustable gastric banding the sleeve gastrectomy the gastric bypass (associating a malabsorption).
Secondary Outcomes
- to compare the production rates of these TRL before and after the bariatric surgery(36 months)
