Capsule Colonoscopy in Crohn's Disease and Its Correlation With Conventional Colonoscopy and Faecal Calprotectin

Study Purpose


  • - To study the feasibility of capsule colonoscopy in patients with Crohn's Disease (CD).
  • - To compare the results of capsule colonoscopy with conventional colonoscopy in assessing mucosal healing.
  • - To correlate the level of faecal calprotectin with the results of capsule colonoscopy and conventional colonoscopy.
  • - To document changes in clinical practice attributable to the capsule colonoscopy findings a) concordant with and b) in addition to the parallel findings at colonoscopy and ileoscopy.
Project design: Cross sectional, prospective, comparative study. Methodology: Patients of the Royal Melbourne Hospital (RMH) and other associated speciality clinics with an established diagnosis of CD who need assessment of mucosal healing and have consented to be part of the study will undergo capsule colonoscopy and conventional colonoscopy on the same day after undergoing bowel preparation. The images of both the conventional and capsule colonoscopies will be recorded. In addition calprotectin (an inflammatory marker in faeces) will be measured in a sample of faeces collected by the patients prior to the colonoscopy day. Professor Macrae and the scholarly selective student researcher will assess the recorded images obtained from capsule colonoscopies once the images have been deidentified. To assess the level of mucosal disease they will use the Simple Endoscopic Score for CD (SESCD). The results of the assessment of mucosal healing obtained from conventional colonoscopy will be compared with those of capsule colonoscopy and levels of faecal calprotectin will then be correlated.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Arms & Interventions


Other: Anti TNF induction therapy 6-12 months

All subjects will be identified through The Royal Melbourne Hospital's IBD clinic, associated specialty clinics and the colonoscopy waiting list of The Royal Melbourne Hospital. The potential participants who have been commenced on Anti TNF induction therapy 6-12 months prior to commencement of the study will be identified. The potential participants identified in this way will be informed of the project at the time of contact and assessment; in some instances the potential participant will be informed of the project via telephone where subjects are remote. The potential participants will be provided an Ethically-approved information sheet at this time. Consent will be gained at the time of assessment.
