Abstract Objective To explore the clinical application of iodine staining chromoendoscopy in differential diagnosis of early esophageal cancer and dysplasia.Methods From July 2015 to August 2019,120 patients with suspected esophageal cancer lesions were selected.All patients were examined by pathology and iodine staining,and the results of pathological examination and iodine staining were analyzed.Results Pathological diagnosis： 27 cases of early esophageal cancer,48 cases of chronic inflammation,45 cases of dysplasia（including mild 17 cases,moderate 19 cases,severe 9 cases）.Early esophageal cancer with iodine staining is mainly unstained,accounted for 88.89%,and mild,moderate,and severe dysplasia iodine staining is mainly light and unstained,each accounting for 88.24%,78.95%,77.78%.The total positive detection rate after iodine staining was 97.22% higher than that before iodine staining（51.39%）（P<0.05）.Conclusion Iodine staining of early esophageal cancer is mainly non-staining,dysplasia iodine staining is mainly light and non-staining,and iodine staining chromoendoscopy has obvious clinical value in the diagnosis of early esophageal cancer and dysplasia.
