  Purpose

The aim of this study is to evaluate three diagnostic methods for assessing small bowel disease in patients with suspected or known Crohn's disease. All patients are examined with ileo-colonoscopy, capsule endoscopy, MRI and CT of the small bowel within 14 days. However, capsule endoscopy is not performed in patients with stenosis detected at ileo-colonoscopy, MRI and/or CT. All investigations are described in a similar pre-defined and standardized fashion and the radiologist and physician responsible for describing the findings at MRI, CT and capsule endoscopy are blinded to the findings at ileo-colonoscopy. The physician in charge of treatment receives a randomised result of either MRI, CT or capsule endoscopy. Thereafter patients are followed during 12 months to evaluate differences in clinical outcome depending on the randomized result. In combination with the diagnostic validity and inter-observer agreement of MRI, CT and capsule endoscopy we seek to establish the optimal diagnostic strategy in these two patient categories.

Intervention Details:
    Procedure: Magnetic resonance imaging, computed tomography scanning and capsule endoscopy
    All patients are examined with ileo-colonoscopy, capsule endoscopy, MRI and CT of the small bowel within 14 days. Capsule endoscopy will not be performed in patients with small bowel stenosis confirmed at ileo-colonoscopy, MRI and/or CT.

Criteria

Inclusion Criteria:

General criteria:

  • Age > 15 years
  • Written informed consent

Patients with established CD are included if assessment of small bowel disease was necessary prior to expected surgery or a change in medical therapy.

Patients with suspected CD are included on either clinical, endoscopical or histological criteria or a combination of these.

  • Clinical criteria: Diarrhoea and/or abdominal pain for more than 1 month (or repeated episodes of diarrhoea and/or abdominal pain) associated with one or more of the following findings: CRP > 5 mg/l, thrombocytosis, anaemia, fever, weight loss, perianal abscess/fistula or a family history of inflammatory bowel disease.
  • Endoscopical criteria (at least one): Ulcerations and/or stenosis in the terminal ileum, inflammation in the colon not involving the rectum, and aphthous ulcerations in the colon.
  • Histological criteria (at least one): Epitheloid cell granulomas, chronic inflammation in the lamina muscularis mucosae or deeper and chronic inflammation in the colon not involving the rectum.

Exclusion Criteria:

  • Acute bowel obstruction, elevated serum-creatinine, severe claustrophobia, cardiac pacemaker, implanted magnetic foreign bodies, use of NSAID's, pregnancy and lactation
