 We retrospectively analyzed clinical features of 45 patients with CEAS(chronic enteropathy associated with SLCO2A1 gene). Our results indicate that this condition occurs predominantly in females ; generally, no patient presents with gross hematochezia but they have anemia. It presents with relatively low inflammation, and 30% of patients have parental consanguinity. Based on the morphologic features, small intestinal lesions are considered to be shallow and sharply demarcated multiple ulcers with an asymmetric formation that occurs commonly in the ileum(except the terminal ileum). A comparison of clinical features by sex revealed that gastric involvement occurs more frequently in females, and clinical findings of primary hypertrophic osteoarthropathy, such as digital clubbing, periostosis, and pachydermia, are significantly more frequently observed in males. In addition to endoscopy, a radiographic examination is imperative as the first-choice procedure for the diagnosis of CEAS. Moreover, extraintestinal manifestation and genetic analysis are helpful in diagnosing this disease.
