Abstract: Objective To investigate the therapeutic value of high-resolution microendoscopy for early esophageal cancer.Methods A total of 60 patients,who underwent esophageal endoscopy,were included in this study.The therapeutic value of high-resolution microendoscopy was investigated with reference to pathological results as golden standard.Results Diagnostic sensitivity,specificity,positive predictive value,negative predictive value and accuracy of microendoscopy for high grade dysplasia/early cancer were 81.22％,94.12％,81.82％,94.12％,91.11％,respectively.Diagnosis of severe dysplasia/carcinoma with high-resolution microendoscopy was highly consistent with that of pathology (K =0.760).Conclusion The high-resolution microendoscopy is of high diagnostic value for early esophagus cancer.
