Study to determine whether the use of an ultrasound completed during an inflammatory bowel disease (IBD) clinic will speed up diagnosis, treatment initiation, reduce complications, save money and reduce investigations compared with our current standard of care.

After being provided with study information and providing written informed consent, participants attending the inflammatory bowel disease clinic will be randomised to standard of care or to receiving an ultrasound during the clinic appointment. This ultrasound result will be used to determine treatment decisions. Participants will have a 6 month follow-up to capture outcome data and further medical record review will be conducted at one year.
