In brief: Very different
Though the diseases may have similar symptoms they are in fact, very different.
By definition, a patient with irritable bowel has no inflammation or other significant abnormalities found in their GI tract which would explain their symptoms. Crohn's patient have visible inflammation somewhere which can be confirmed with biopsy. Both commonly have abdominal pain and/or diarrhea.
