Two Cases of Eosinophilic Gastroenteritis and One Case of Hypereosinophilic Syndrome Presenting with Various Gastrointestinal Symptoms / 대한소화기내시경학회지

ABSTRACT

Eosinophilic gastroenteritis is a rare disorder of unknown origin that is pathologically characterized by marked infiltration of eosinophils in the wall of the gastrointestinal tracts. Eosinophilic gastroenteritis is often classified according to the layer of the bowel wall involved. We experienced two cases of eosinophilic gastroenteritis. One case having whole small bowel wall involvement resulting in small bowel obstruction and eosinophilic ascites underwent bowel resection followed by oral steroid treatment. The other case having mucosal layer involvement with chronic diarrhea and hypoalbuminemia was treated with oral corticosteroid and responded dramatically. In addition, we report one case of hypereosinophilic syndrome involving the gastrointestinal tracts. The patient presented with abdominal pain, ascites, and urticaria. and also showed good response to oral steroid.
