  Purpose

Growing evidence suggests that bariatric surgery is a relevant treatment for severely obese patients, especially those with metabolic complications, as it significantly reduces weight, hypertension and ameliorates glycemic control. Its action on adipose tissue distribution and in particular on epicardial adipose tissue EAT remains unknown. Whether metabolic improvement is associated with EAT reduction is also unknown.

The researchers thus investigated the effect of bariatric surgery on EAT in severely obese patients. The primary endpoint of this study was the change in EAT amount 6 months after bariatric surgery.

Primary Outcome Measures:
  • The change in EAT amount 6 months after bariatric surgery. [ Time Frame: 36 months ] [ Designated as safety issue: No ]
    We thus investigated the effect of bariatric surgery on EAT in severely obese patients.


Secondary Outcome Measures:
  • Evaluation of 3 parameters [ Time Frame: 36 months ] [ Designated as safety issue: No ]
    1. to evaluate the variation in myocardial, hepatic , pancreatic and triglyceride content
    2. to evaluate the variation in left ventricular function or myocardial function
    3. and to describe the relationships between changes in visceral abdominal fat, subcutaneous fat and epicardial fat


Estimated Enrollment: 35
Study Start Date: September 2010
Estimated Primary Completion Date: March 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
severely obese patients
35 patients addressed for severe obesity in the Endocrinology department of Marseille North Hospital before (V1) and 6 months (V2) after bariatric surgery
Procedure: bariatric surgery
The bariatric surgery is a relevant treatment for severely obese patients those with metabolic complications, as it significantly reduces weight, hypertension and ameliorates glycemic control.

Detailed Description:

The best of our knowledge, no study has really addressed whether this EAT was modulated by diet or therapeutics like bariatric surgery. The researchers were particularly interested in studying the impact of bariatric surgery and of weight loss on the amount of EAT and whether reduction in EAT could have a positive impact on myocardial function.
