[Ulcerative colitis and Crohn disease: echographic diagnosis with water enema].

Water enema procures a suitable acoustic window for ultrasonographic study of the colon, allowing a detail vision of the lumen and colon wall, as well as large bowel intestine surround connective tissue. In this work we present echographic findings in two patients with active and severe intestinal inflammatory disease. Ultrasound scanning results were confirmed by colonoscoy and histological test. Distinction between ulcerative colitis and colonic Crohn's disease is possible because of different echographic pattern. This findings show than colonic echography may be a very useful diagnostic technique in detection and differentation of inflammatory large bowel diseases.
