Ulcerative colitis is confined to the rectum and colon, and affects the mucosa and the submucosa. In some instances, a short segment of terminal ileum may be inflamed this is referred to as backwash ileitis. Unlike Crohn s disease, the deeper longitudinal muscular layers, serosa, and regional lymph nodes are not usually involved. Fistulas, perforation, or obstruction are uncommon because inflammation is usually confined to the mucosa and submucosa. 

Systemic complications of Crohn s disease are common, and similar to those found with ulcerative colitis. Arthritis, iritis, skin lesions, and liver disease often accompany Crohn s disease. Renal stones occur in up to 10% of patients with Crohn s disease (less frequently with ulcerative colitis) and are caused by fat malabsorption, which allows for greater oxalate absorption and formation of calcium oxalate stones. Gallstones also occur with greater frequency in patients with ileitis, possibly because of bile acid malabsorption at the terminal ileum.
