Design outcomes

Primary

Measure	Time frame
Detection rate for small bowel lesion in patients with Crohn's disease by balloon-assisted enteroscopy comparison with MR enterography.	—

Secondary

Measure	Time frame
1) Detectability for transmural or extraluminal small bowel lesion in patients with Crohn's disease by MR enterography. 2) Detectability for small bowel stricture in patients with Crohn's disease by balloon-assisted enteroscopy and MR enterography. 3) Correlativity for enteroscopy score and MR enterography score. 4) Comparison with the findings of imaging modality (balloon-assisted enteroscopy, MR enterography) and disease activity index, CRP or fecal calprotectin.	—
