The goal of this clinical trial is to learn whether a camera pill examination of the whole bowel can be used to diagnose Crohn's disease instead of colonoscopy and a small bowel examination (either MRI or camera pill) in patients aged 18-40 years suspected of having Crohn's disease.
The main question it aims to answer is:
How many patients examined with a camera pill examination of the whole bowel will have a complete examination of the whole bowel and have a diagnosis made without need for any more examinations?
Researchers will compare with patients examined with colonoscopy and a small bowel examination.
Participants will:
* Be examined with either a camera pill examination of the whole bowel, or a colonoscopy and a small bowel examination
* Have their electronic medical records checked to see if a diagnosis has been made
* Have an interview every three months if diagnosed with an inflammatory bowel disease or after a year if no disease was found
