Objective To research the characteristics of early esophageal cancer's endoscopy and its clini-cal diagnosis. Methods Retrospective analyze the clinical symptoms and endoscopy performance of the 24 cases of early esophageal cancer which were confirmed by opemtion. Results Unaided eye observing of 24 cases of early e-acphageal cancer:diameter of pathological changes within 1.0 cm,there are four cases of the surface rough,turbidity,vascular fuzzy texture, congestive mucosa, small pieces of rotten to the core, around the realm of clear, easy bleeding by touch of three cases. Mucosa focal irregular plaquelike erosion or superficial helcosis of five cases Mucosa mild uplift,smooth surface or erosion, with slightly different colors of 10 cases ( including one case of pelypoid change) Mucosa fo-cal wormhole-like change, a slight hollow, moss-covered, rubeosis or bleeding lesions after water rinse, irregular and clear borders of two cases, pathology report: one case of small cell carcinoma,one case of adenocarcinoma (cardia),High-level intraepithelial neoplasia transformation nine cases, one case of poorly differentiated adenocarcinoma, 12 ca-ses of squamous cell carcinoma. Conculsion Endoscopic early esophageal cancer for the mainfeatures of the mucous membrane color changes, mucosal thickening, transparency and mucosal vascular network st ructure changes, and mu-cosal rough, nodules, plaques, erosion and uplift superficial, shallow depression and other patterns chang, GeneraUe-sions were confined or isolated like chang, irregular, and the mucous membrane around the borderclear. Clinicalofte misdiagnosed, missed diagnosis, early diagnosis to have significant value.
