What are the tests for ulcerative proctitis?

Proctitis: Proctitis by definition is inflammation of the rectum of any cause. As you'd expect, defecation becomes painful & stool is usually mixed with pus, frank blood, &/ or clots. Proctitis may be due to inflammatory bowel disease, chemical or mechanical trauma, infection, ischemia of the rectosigmoid junction. Investigation at minimum requires at least sigmoidoscopy with biopsy & stool analysis.
