The disease activity index under intestinal color ultrasound was evaluated by SUS-CD, and the disease activity index under capsule endoscopy was evaluated by CECDAI. Active lesions under intestinal color ultrasound were defined as SUS-CD ≥ 1, and active lesions under capsule endoscopy were defined as CECDAI ≥ 3.9. All subjects underwent intestinal color ultrasound and capsule endoscopy at baseline and 3 months after treatment. To compare the correlation between SUS-CD and CECDAI before and after treatment, and to compare the role of intestinal color ultrasound and capsule endoscopy in monitoring Crohn's disease in small intestine.
