Brief summary
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.
Detailed description
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| the Simple Ultrasound Activity Score for Crohn's Disease (SUS-CD) | At baseline | The Simple Ultrasound Score for Crohn's Disease \[SUS-CD\] is constituted by Bowel wall thickness (BWT) and colour Doppler. BWT：\<3 mm gets 0 score, 3 to 4.9 mm gets 1 score, 5 to 7.9 mm gets 2 scores, and intestinal wall thickness of ≥8 mm gets 3scores. Colour Doppler score：No or single vessel gets 0 score, 2-5 vessels per cm2 gets 1 score, \>5 vessels per cm2 gets 2 scores. |
| the Capsule Endoscopy Crohn's Disease Activity Index(CECDAI) | At baseline | The CECDAI was designed to evaluate three main parameters of Crohn's disease: inflammation (A), extent of disease (B), and stricture (C), in both the proximal and distal segments of the small bowel. The final score was calculated by adding the two segmental scores: CECDAI =(\[A1×B1\] +C1) +(\[A2×B2\] +C2). |
