Endoscopic Features and Diagnostic Procedures of Eosinophilic Gastroenteritis.

No specific endoscopic features for eosinophilic gastroenteritis (EGE) have been reported previously. This study therefore evaluated the endoscopic findings of six patients with EGE. The diagnosis was confirmed based on gastrointestinal symptoms, pathological findings on biopsy, and the absence of other diseases. The site of the lesion was identified based on eosinophilic infiltration with ≥20 cells per high-power field during a pathological specimen analysis. Flattening of the small intestinal villi was observed in four patients; we speculate that this may be a specific feature in the diagnosis of EGE.
