- W3146034348 abstract "Objective To evaluate the value of narrow band imaging(NBI) in the diagnosis of early squamous esophageal cancer and precancerous lesions.Methods Four thousand and fifty-six patients were examined by routine endoscopy,NBI and iodine chromoscopy,one hundred and fourteen lesions in 82 patients were screened.Of all lesions were detected by NBI with magnification and targeted biopsy.The differences among routine endoscopy,NBI and iodine chromoscopy,and the consistency between IPCL and histological findings were assessed.Results Compared to NBI and iodine chromoscopy,especially flat lesions,there was a high missed diagnosis rate in diagnosis of early squamous esophageal cancer and precancerous lesions by routine endoscopy.With NBI and iodine chromoscopy,the incidence rate of lesions was 78.0% and 79.8%,respectively.For iodine staining,85.7% Grade Ⅰ was high grade intraepithelial neoplasia(HGIN),and 66.0% Grade Ⅱ/Ⅲ was low grade intraepithelial neoplasia(LGIN).For NBI,80.4% Grade Ⅰ was HGIN,but there was no specificity in diagnosis LGIN.In appearance of IPCL,92.9% Type Ⅳ/Ⅴ was HGIN,89.4% Type Ⅱ/Ⅲ was LGIN,and it has a relatively better consistency in IPCL with histological findings.Conclusion There is a high detection rate in diagnosis of early squamous esophageal cancer and precancerous lesions by Lugoul's iodine staining and NBI endoscopy.It's probably that IPCL patterns by NBI with magnification can provide scientific basis for both the endoscopic theraphy of early esophageal cancer and the omen of postoperative recurrence." @default.
