Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 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 Crohn’s 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
| Measure | Time frame |
|---|---|
| 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 5 weeks after all the examinations. | — |
