Research progress in diagnosis and treatment of eosinophilic gastroenteritis / 上海交通大学学报（医学版）

ABSTRACT

Eosinophilic gastroenteritis (EGE) is a rare chronic disease of digestive system, characterized by the eosinophil infiltration of the gastrointestinal tract and the thickening of the gastrointestinal wall. At present, the etiology and pathogenesis of EGE are still unclear. Accompanied with eosinophilia and elevation of serum immunoglobulin E, the clinical manifestations of EGE are dependent on the location of lesions and the extent or depth of eosinophil infiltration in the gastrointestinal tract. The thickening or edema of the gastrointestinal wall, nodular-like changes, intestinal stenosis and ascites can be regarded as common radiological findings of EGE, while erythema, hyperemia or edema, erosion and ulcer of mucosal are the endoscopic features of EGE. Tissue biopsy is helpful for the diagnosis of EGE. However, with unspecific clinical manifestations, laboratory tests, radiological and endoscopic findings and unidentified cut-off count of pathological diagnostic criteria, EGE is very difficult to be diagnosed. Therefore, this paper mainly reviews the research progress in the diagnosis and treatment of EGE, attempting to improve the clinicians' understanding of EGE.
