Trial design
CTIS Part I — objectives, methods, condition coding
Main objective
Scope: Safety, Diagnosis, Efficacy
Develop a method for investigating the small bowel in Crohn’s disease using transabdominal ultrasound and microbubbles as luminal contrast.
Secondary objectives 12
- Investigate adverse events and severe adverse events
- Investigate tolerability of the procedure
- Investigate if luminal contrast can be used to detect stenosis in the terminal ileum
- Investigate if luminal contrast can be used to detect ulcers >0,5cm in the terminal ileum
- Investigate if luminal contrast can be used to separate large ulcers (0.5-2 cm) and very large ulcers (>2 cm) in the terminal ileum
- Investigate if luminal contrast affects the measurement of wall thickness in the terminal ileum
- Investigate if luminal contrast can be used to detect motility in the small intestine
- Investigate intestinal motility in patients with ulcers in the terminal ileum.
- Investigate intestinal motility in patients with stenosis in the terminal ileum.
- Investigate if intestinal motility is affected by the degree of inflammation defined by ulcer size and intestinal wall thickness.
- Investigate if there are differences in motility findings between patients with Crohn’s disease and healthy volunteers.
- Investigate if luminal contrast can be used to detect postsurgical relapse in the neoterminal ileum.

Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- Number of patients with homogenous contrast filling of the entire lumen of the terminal ileum within 1 hours of ingestion, with a clear separation between the lumen and intestinal wall as visually assessed by the examiner.
Secondary endpoints 12
- Number of patients who develop adverse events and severe adverse events
- Number of patients who are willing to undergo the procedure again
- Number of patients with detected stenosis in the terminal ileum with and without contrast, as visually assessed by the examiner and confirmed on endoscopy.
- Number of patients with detected ulcers >0,5cm in the terminal ileum with and without contrast, as visually assessed by the examiner and confirmed on endoscopy
- Number of patients with large (0,5cm-2cm) and very large (>2cm) ulcers in the terminal ileum with and without contrast, as visually assessed by the examiner and confirmed on endoscopy.
- Interobserver variability for wall thickness in the terminal ileum with and without contrast as visually assessed by the examiner.
- Number of patients with visible intestinal contractions with and without contrast
- Number of patients with ulcers and visible intestinal contractions in the terminal ileum
- Number of patients with stenosis and visible intestinal contractions in the terminal ileum
- The correlation between ulcer size, bowel wall thickness and frequency of contractions in the terminal ileum.
- The correlation of motility findings in Crohn’s patients and healthy volunteers
- The number of patients with detected disease activity in the neoterminal ileum with and without contrast.
