Abstract:
Objective To investigate the diagnostic value of quantitative analysis of the color change of iodine staining for early esophageal cancer.Methods A total of 58 patients with suspected esophageal diseases were recruited to this study.The lesions were stained with lugols iodine,and biopsies were performed.Quantitative analysis of color change under endoscopy was also performed by analysis software and the results were compared with pathological findings.Results A total of 62 iodine-unstained lesions in 58 patients were found,includiug 19 chronic inflammation,13 low-grade intraepithelial neoplasia,11 high-grade intraepithelial neoplasia and 19 squamous cell cancer.The color parameters of R/R'(red) and H/H'(hue) were significantly different among the four groups (P＜0.05).Conclusion Computerized chromoendoscopy is helpful in determining pathological characteristics of esophageal lesions,thereby improving the accuracy of endoscopic biopsy and the diagnosis rate of early esophageal cancer.
