복강경을 통한 조직 생검으로 진단한 호산구성 소장염

Eosinophilic gastroenteritis is a rare disease characterized by the eosinophilic infiltration of the gastro-intestinal tract without involvement of organs outside the gastrointestinal tract and may be misdiagnosed in clinical practice. The pathophysiology of eosinophilic gastroenteritis is not known well. We report a case of serosal eosinophilic enteritis presenting sterile eosinophilic ascites, peripheral eosinophilia and abdominal pain. Diagnosis was confirmed by laparoscopic biopsy of small bowel. The patient was improved dramatically with prednisolone therapy. (Korean J Gastrointest Endosc 2000;20:289-293)
