title: [Differences and similarities of Crohn disease and ulcerative colitis].
abstract: Sometimes the demarcation of a colitis granulomatosa Crohn from an ulcerous colitis  renders diagnostic difficulties. Also when certain communities of the two clinical pictures are recognizable, nevertheless the differences prevail. The judgment of the success of various forms of therapy and the further clarification of etiology and pathogenesis demand the differentiation in every case. Anamnesis, clinic, radiological findings, endoscopic and bioptical signs are building stones which in their totality render possible the findings of the diagnosis. Bioptical investigations in various stages of activity and after the beginning of the treatment are suited further to restrict the number of the non-classifiable colitides.
