About

The investigators propose an exploratory study aiming at assessing the impact of surgical bariatric treatment on the improvement of pancreatic lesions detected by MRI.

Pancreatic MRI will be performed in severe-obese patients with a planned bariatric surgery, before and 6 months after bariatric surgery.

To assess the impact of bariatric surgery on pancreatic Magnetic Resonance Imaging (MRI) parameters in severe-obese patients

Enrollment: 25 estimated patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Adults (aged 18 to 65 years) with a planned for bariatric surgery (sleeve gastrectomy) according to HAS criteria
• Patients with severe obesity (BMI≥35)

Exclusion criteria

• Patients with problem of alcohol abuse (previous or current)
• Patients with problems of understanding
• Patients with previous acute or chronic pancreatitis
• Patients with contraindication to MRI (active implantable medical devices, pacemaker, claustrophobia ...)
• Inability to undergo MRI due to weight excess
• Pregnant or breastfeeding woman
• Absence of free and informed consent
• Non affiliation to a social security regime or CMU (Universal health coverage)
• Patient under AME (State medical aid)

MRI before and 6 months after bariatric surgery

Experimental group

Description:

Recruitment of patient with planned bariatric surgery in Louis Mourier Hospital by the nutritionist, during the preoperative day hospitalisation (performed during the multidisciplinary preparation for bariatric surgery) when patients are deemed eligible for bariatric surgery according to HAS (High Authority of Health) criteria. Programming of MRI in the month between preoperative visit and surgery. During this exam without injection of contrast agents in the radiology department of Louis Mourier Hospital, additional sequences with specific acquisitions as previously validated in humans will be performed for the study. Bariatric surgery will be performed as in usual care in Louis Mourier hospital. The same MRI will be performed in day hospitalization scheduled 6 months after surgery.

Treatment:

Radiation: Magnetic Resonance Imaging
