Before infusion, capsule endoscopy showed multiple oval ulcers with purplish red color change and thin fur attached on the surface. Congestion and edema of the mucosa can be seen around the ulcers which were widely distributed in the small intestine (A, B). Repeated capsule endoscopy showed improvement in ulcerations and inflammation 10 weeks after the last infusion (C, D). Most of the ulcers had healed, leaving a small sheet of erosion (arrow).
