We performed a retrospective analysis on three patients diagnosed with EGE (eosinophilic gastroenteritis) at our hospital and 90 cases obtained from a case database. The cases' genders, ages, peripheral eosinophils, ascites, endoscopic findings, biopsy findings, diagnostic scores, and rates of glucocorticoid use were evaluated. The gender ratio was 40 males to 53 females, and the median age was 50. 78.5% of cases had peripheral eosinophilia. The prevalence of allergic diseases was 31.2%, and the incidence of ascites was 34.4%. 83.9% of endoscopic findings were positive, and 92.5% of biopsies were positive. The total rate of glucocorticoid use was 77.4%. When both score <5 and age <33 conditions were met, the rate of glucocorticoid use was approximately 30%, meaning it was possible to avoid glucocorticoid use.
