Chronic Eosinophilic Gastritis Presenting as Gastric Outlet Obstruction in a Young Man: A Case Report.

Abstract

Eosinophilic gastritis, a relatively rare condition characterized by eosinophilic infiltration of the gastrointestinal wall, has a chronic course involving relapses and remissions. Herein, we describe the case of a 25-year-old man with chronic eosinophilic gastritis complicated by gastric outlet obstruction. The patient had a history of persistent gastrointestinal symptoms since adolescence and had developed severe dyspepsia and vomiting two months before presentation. Eosinophilic gastritis was confirmed using endoscopy and biopsy. The symptoms improved after steroid treatment, although the mucosal lesions did not completely resolve. This case shows that eosinophilic gastritis can have a chronic course with persistent mucosal lesions, despite symptomatic improvement. Early diagnosis and appropriate treatment of eosinophilic gastritis are important for preventing chronic gastric mucosal changes.
