2. Figure 1
Typical endoscopic findings in UC and CD. (A–C) UC. (A) UC with mild inflammation and reduced haustration, vascular transparency is missing. (B) Moderate inflammation with reduced haustration. The mucosa is edematous, covered with fibrin, and shows multiple erosions. (C) Severe inflammation with inflammatory narrowing of the lumen through pseudopolyps. (D–F) CD. (D) Mild inflammation with an isolated small aphthous mucosal lesion. (E) Moderate inflammation with some flat longitudinal ulcers. (F) Severe inflammation with deep snail track ulcers. (G–H) Chronic mucosal lesions without active inflammation. (G) Distinct formations of scars in patients with UC. The corresponding abdominal flat film (barium enema) shows a rigid colon with no haustration. (H) Chronic, fibrotic stenosis of the terminal ileum in a patient with CD. (I) Chronic destruction of the ileocecal valve in CD.

4. Figure 3
(A, B) Plain abdominal radiographs of patients with IBD presenting with acute abdominal pain. (A) Extremely dilated colon in severely acute UC. (B) Small bowel ileus in a patient with CD that shows typical fluid levels. The patients had an ileal fibrotic stenosis. (C–E) Small bowel follow-through in a patient with a long, fibrotic stenosis in the terminal ileum. Excretion of the contrast agents was extensively prolonged. (C) Radiograph taken after day 1. (D) Day 2. (E) Day 3.

5. Figure 4
Sonography of the bowel in conventional and power Doppler modes. (A) Patient with acute UC (pancolitis). Continuous thickening of the bowel wall up to 3 mm. Preserved lamination of the bowel wall, accentuated submucosa, and irregular mucosal border. (B) Increased perfusion of the bowel wall in the power Doppler mode. (C, D) CD patient with thickening of the intestinal wall of the terminal ileum (up to 7 mm) with relative stenosis. Within the region showing the most prominent wall thickening, 4 fistula tracts are found that connect with the sigmoid colon.
