Comparative Study of Intestinal Color Ultrasound and Capsule Endoscopy in Monitoring Crohn's Disease

Comparative Study of Intestinal Color Ultrasound and Capsule Endoscopy in Monitoring Crohn's Disease

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. All subjects underwent intestinal color ultrasound and capsule endoscopy at baseline and at the third month of 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.

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.
