Study hypothesis
Comparison of two new techniques for detection of small bowel pathology: magnetic resonance (MR) enteroclysis and videocapsule enteroscopy with double-balloon enteroscopy with respect to diagnostic yield, accuracy of findings, and patient preference.
Please note that as of 02/10/2008 the anticipated end date was extended. The initial anticipated end date was 01/10/2008. As of 06/02/2009 the anticipated end date was again extended. The previous anticipated end date was 01/01/2009. As of 24/03/2009 inclusion to this trial is closed.
Ethics approval

Primary outcome measure
Diagnostic yield, including location and nature of lesions. The pathologic findings in the small bowel of the different diagnostic methods will be correlated with each other to analyse location and nature of lesions. For patients with known or suspected Crohns disease of the small bowel, a comparison will be made for prevalence, location, severity of inflammatory lesions, and complications such as formation of stenotic lesions. For patients with gastrointestinal blood loss, the techniques will be compared for prevalence and location of bleeding foci and characters of the lesion. The findings at the double balloon endoscopy will be used as the gold standard.
Secondary outcome measures
Patients appreciation of the different diagnostic methods. This will be analysed by means of a questionnaire. Patients will be asked to repeatedly fill out the same questionnaire, 24 hours before and after each examination and five weeks after all the examinations.
