ABSTRACT
INTRODUCTION: Eosinophilic gastroenteritis of unknown origin could be isolated or integrated in idiopathic hypereosinophilic syndrome. Clinical expression is variable since the lesion may affect any area of the gastrointestinal tract and any layer of the wall. EXEGESIS: A 25-year-old male patient had digestive symptoms such as peritoneal, obstructive and diarrheal signs, associated with blood eosinophilia, giving evidence for eosinophilic jejuno-ileitis. Computer tomography revealed an extensive obstruction of the jejuno-ileum and thickening of the intestinal wall. The diagnosis was obtained using laparoscopy and controlled wedge biopsy, which showed a predominantly external infiltration of the intestinal wall by eosinophils. The disease evolution was favorable with corticosteroid therapy. CONCLUSION: Worrying and persistent digestive symptomatology, associated with blood eosinophilia, particularly when intestinal wall infiltration is revealed by computer tomography, should lead one to perform a laparoscopy to guide a surgical biopsy of the intestinal wall.
