Introduction： EoE （eosinophilic esophagitis） is an inflammatory condition characterized by a dense eosinophilic infiltrate in the esophageal epithelium. In Brazil, it remains a poorly diagnosed disease due to the lack of interaction between the clinician, the endoscopist, and the pathologist. The diagnosis is performed by histological study of esophageal biopsies, with at least fifteen eosinophils per high-power field （EOS/HPF）. Some doubts remain with respect to patients with a clinical picture and symptoms compatible with the disease （EoE）, but who have a lower number of eosinophils than established. The main objective of this study was to create an endoscopic classification for EsEo （esophageal eosinophilia）, which pointed the way to the endoscopist towards the diagnosis. Methods： This study was a prospective, two-year study, at a gastrointestinal endoscopy center where all patients with endoscopic symptoms and/or endoscopic findings suggestive of EsEo were biopsied for histological examination of EOS/HPF. After the study and compilation of the results, a retrospective study was performed, based on a review of electronic medical records, where the same diagnosis was searched, although at a period when this classification was not adopted. Results： A total of 4,251 endoscopies were performed between September 2011 and September 2013. Two biopsies were performed, aimed at lesions, in 133 patients with clinical picture or imaging suggestive of EsEo. Eosinophils were found in 55 patients, corresponding to an incidence of 1.29% of the total population studied and 41.35% of the suspected cases of the disease. EoE was diagnosed in 24 patients during the period of this study. In the two-year retrospective study, only two cases of EoE were found. Conclusions： The results of this study demonstrate that the endoscopic standardization of esophageal lesions, suggestive of eosinophilia, in this case by classification, alerts the endoscopist for the diagnosis of EoE, prompting
