Behcet disease (BD) is an idiopathic vasculitis affecting multiple organs. Involvement of the GI tract is seen in up to 50% of cases. Specific GI tract manifestations include:
- ulceration: most common finding
- localized - usually in the ileocecal region
- diffuse - usually in the colon
- ulcers are deep, often penetrating to the serosal layer
- recur at surgical anastamotic sites
- thickened mucosal folds in the small bowel
- increased incidence of fistulas and perforations
- microperforations are common due to deep, penetrating nature of ulcers
