Small bowel segmentExamination (n)Patients with small lesions (n)Patients with large lesions (n)
Data were stratified with respect to the different examination techniques and the small bowel segments. Small lesions were defined as patchy erythema, villous denudation, and aphthoid ulcerations. Large lesions were defined as large/fissural ulcers, cobblestoning, and stenosis. Small and large lesions can occur in the same patient.
*p = 0.007 v CTE (McNemar test).
†The ileum was reached in only 40 patients (jejunal capsule retention in one patient).
Ten capsules did not reach the colon, implying that the terminal ileum was not reached. In one patient the colonoscope could not be passed into the terminal ileum
