[Limitations in the internistic treatment of ulcerative colitis and Crohn's disease]

Aetiology of ulcerative colitis and Crohn's disease is unknown. Therefore causal therapy is not possible. Conservative treatment for both diseases is of antiinflammatory, symptomatic and substituting nature. Surgical intervention is indicated if conservative treatment fails or if dangerous complications occur. The right moment for an operation can only be determined in close cooperation between internist and surgeon.
