Ischemic colitis has a distinctive endoscopic appearance; endoscopy can also facilitate alternate diagnoses such as infection or inflammatory bowel disease. Biopsies can be taken via endoscopy to provide more ...
The autoantibody pANCA is found in 10–15% of Crohn's disease cases, in 60–70% of ulcerative colitis cases, and in less than 5% of patients with other types of colitis that aren't inflammatory bowel disease.
