The rectum is always involved in ulcerative colitis, and the disease primarily involves continuous lesions of the mucosa and the submucosa. Both ulcerative colitis and Crohn disease usually have waxing and waning intensity and severity. When the patient is symptomatic due to active inflammation, the disease is considered to be in an active stage (the patient is having a flare of the IBD). (See .)

Surgical intervention for ulcerative colitis is curative for colonic disease and potential colonic malignancy, but it is not curative for Crohn disease.
