Abstract：Objective:To investigate the diagnostic value of iodine staining under endoscopy for esophageal cancer and precancerous lesions.Method:One hundred and eighty-four patients with suspicious esophageal lesions under gastroscopic biopsies in our hospital from June 2015 to December 2015 were selected as the objects.All patients were dyed with iodine solution and were given pathological examination.The relationship between the results of pathology and iodine solution staining were collected and analyzed.Result:Among of the 184 patients,42 cases(22.8%) were found with esophageal squalors carcinoma,12 cases(22.8%) with severe esophageal dysplasia,30 cases(16.3%) with moderate esophageal dysplasia,27 cases(14.7%) with mild esophageal dysplasia,51 cases(27.7%) with chronic esophagi and 22 cases(12.0%) with squalors cell hyperplasia.After iodine solution staining,the esophageal cancer were characterized without staining and the proportion was 90.5%(38/42).The precancerous lesions were characterized with light staining and the proportion was 97.1%(67/69).The esophageal cancer and severe esophageal dysplasia were characterized without staining and the proportion was 87.0%(47/54).Conclusion:The esophageal cancer and esophageal dysplasia were characterized without or with light staining under the endoscopic iodine solution staining,which have an important value in the screening of esophageal cancer and precancerous lesions.
