Comparison of Endoscopy and Diffusion-weighted Enterography-MRI for the Diagnosis of Crohn's Disease Recurrence Following Ileocolic Resection: a Pilot Study

Not Applicable

• Conditions: Crohn's Disease
• Interventions: Other: MRI enterography

• Registration Number: NCT02867540
• Lead Sponsor: CHU de Reims

Brief Summary

Nearly three-quarters of patients with Crohn's disease have small bowel involvement and 80% of them will have complications that will require a surgical procedure, usually an ileocolonic resection with ileocolonic anastomosis. The rate of recurrence at the anastomosis site and in the ileum after surgery, whether symptomatic or not, is high, at least 60% in one year and 80% within three years. The gold standard for monitoring being ileocolonoscopy, endoscopic surveillance is recommended in these patients, once between 6 to 12 months after surgery and then every 2 years.

The MRI enterography is a validated technique for the assessment of small bowel Crohn's disease. The enterography MRI is a validated technique for the assessment of small bowel Crohn's disease. The MRI enteroclysis was evaluated in two studies compared to endoscopy, with excellent performance in terms of recurrence detection sensitivity and suggested as an alternative to it to avoid an invasive procedure repeated in these patients. The MRI enterography (without enteroclysis) does not provide as good distension of the bowel loops as MRI enteroclysis because it relies on the principle of oral ingestion prior to the examination of large amounts of liquid. However, it is much better tolerated by the patient, does not involve radiation that exists with enteroclysis, is much simpler to use and requires no special equipment to magnetic fields.

Detailed Description

Determine the diagnostic performances of MRI enterography for the diagnosis of recurrence at the anastomosis site and in the ileum in patients with Crohn's disease who have had ileocolonic resection.

Assess the value of diffusion sequences of MRI enterography for the diagnosis of recurrence at the anastomosis site and in the ileum in patients with Crohn's disease who have had ileocolonic resection.
