Participants will undergo diagnostic assessments (colonoscopy, MRI, ultrasound and Pillcam Crohn's capsule) at 2 time points- 1 year apart. Colonoscopy, MRI and ultrasound all form part of routine disease assessment for patients with IBD and the use of these assessments during the study will not be different to standard care. The Pillcam Crohn's capsule is not yet part of routine care, but is merely an updated, higher definition iteration of existing capsule endoscopy systems. The risks associated with the Pillcam Crohn's capsule are no different to standard capsule endoscopy. Previous versions of capsule endoscopy have been shown to be comparable to other diagnostic modalities in the assessment of inflammatory burden in inflammatory bowel disease patients. The procedures will be performed within a 2 week period, so that they are able to be compared to each other as accurately as possible. There is no prescribed order of interventions, however the person reporting each intervention will be blinded to the results of the patient's other interventions. Colonoscopy- this is a standard diagnostic and therapeutic procedure for patients with inflammatory bowel disease. It involves taking a bowel cleansing preparation 1 day prior to the procedure. The procedure involves having a sedative medication administered and a camera with a light is inserted via the anus/rectum to pass through the entire large bowel. The large bowel and last few centimetres of the small bowel is examined by the colonoscope. The procedure usually takes between 15 to 45 minutes and will be performed by a gastroenterologist. Capsule endoscopy- This procedure involves having a similar bowel cleansing preparation as a colonoscopy. The patient will then ingest/swallow a capsule (that |
