 Ischemic enteritis is a reversible ischemic lesion caused by a miniature circulatory disease of the intestine. Stricturing types are often found and the average age of the patients is 62.5 years. The initial symptoms include abdominal pain and nausea/vomiting, and show an ileus symptom in the chronic stage. The patients tend also suffer from hypertension, ischemic heart disease, et al. The lesion is most frequently found in the ileum. Radiography and enteroscopy of the small intestine show concentric tubular stenosis, dilated proximal bowel and multiple small ulcers. The macroscopic finding of the resected specimen in this case revealed concentric tubular stenosis, segmental annular ulcer, and marked thickening of the wall. The histological characteristics of the lesions are fibrosis mainly in the submucosa and are relatively marked by inflammatory infiltrate consisting chiefly of lymphocytes and plasma cells. Ischemic enteritis of the stricturing type is progressive and results in complete stricture, so requires an operation.
