title: [Ulcerative colitis].
abstract: Ulcerative colitis is an immunologic disorder of the intestine which involves the mucosa and sometimes the submucosa. It has a chronic relapsing course, affects the colon and occasionally the terminal ileum. This so called backwash ileitis is overall very rare and of limited clinical importance. Usually the inflammation starts in the rectum and may extend in a proximal and continuous fashion to the rest of the colon. Symptoms consist of frequent loose bloody stools, cramps and weight loss. It is important and frequently neglected that patients especially (but not exclusively) with a limited degree of colonic involvement up to the splenic flexure are treated topically with mesalamine and budesonid or hydrocortisone by suppository, enema or foam. In case of more severe colitis oral mesalamine, systemic corticosteroids and other immunosupressors should be added to the therapy.
