Official title: Camera Capsule Endoscopy in the Routine Diagnostic Pathway for Colorectal Diseases
Run by Odense University Hospital · NCT06475560 · Data updated 2026-11-12
This trial tests whether colon capsule endoscopy can be used instead of or before conventional in-hospital colonoscopy for adults referred for colorectal evaluation.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults referred for colonoscopy who can give written informed consent and do not have exclusions such as suspected colorectal tumor, significant bowel stenosis, prior major GI surgery with stoma, pacemaker/defibrillator, pregnancy, severe kidney disease, known chronic constipation, or allergy to bowel prep.
✕Probably not a fit
Patients requiring inpatient or therapeutic colonoscopy, those with imaging suggestive of a colorectal tumor, those needing biopsy for suspected microscopic colitis, or anyone with contraindications to capsule passage are unlikely to benefit from the CCE pathway.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Adults referred for colonoscopic assessment are assigned to either an out-of-hospital colon capsule endoscopy (CCE) pathway or conventional colonoscopy (CC) to compare diagnostic yield, downstream procedures, and service burden. The trial enrolls symptomatic adults able to provide informed consent and excludes those with suspected tumors on imaging, severe comorbidities, prior major gastrointestinal surgery with stoma, pacemakers, pregnancy, chronic constipation, or other contraindications. Key outcomes include diagnostic quality, rates of required re-investigation or therapeutic follow-up, and impacts on endoscopy workload and patient pathway. The protocol aims to define realistic thresholds for treating versus observing small lesions and to test whether CCE can safely decongest hospital endoscopy services.
Why it matters
Potential benefit: If successful, CCE could reduce the number of uncomfortable, hospital-based colonoscopies and expand access to bowel diagnostics while easing endoscopy service workload.
How similar studies have gone: Large implementations in Scotland and England and several clinical trials have shown CCE to be safe and diagnostically high-quality in routine use, but consistently high (45–60%) re-investigation rates remain a major limitation.
