NBI及碘染色对早期食管癌及其癌前病变的诊断价值

摘要

Objective To investigate the value of narrow band imaging and iodine staining in the diagnosis of early e-sophageal cancer and precancerous lesions .Methods 52 patients who were diagnosed as early esophageal cancer and precancer-ous lesions were selected .Conventional endoscopy ,NBI and iodine staining were applied .Results Lesion contour sharpness of NBI and iodine staining were almost the same;NBI had significantly lower detection rate of low-level mucosal lesions than that of iodine staining;NBI and iodine staining in detection of low-level mucosal lesions were mainly Ⅱ,Ⅲgrade,andⅠgrade in detec-tion of high-level mucosal lesions .Conclusion NBI can clearly show the capillary structure and morphology of early esophageal cancer.NBI combined with iodine staining can effectively improve the diagnosis rate of early esophageal cancer and precancerous lesions.%目的：探讨NBI及碘染色对早期食管癌及其癌前病变的诊断价值。方法选择52例经内镜和病理诊断为早期食管癌及癌前病变的患者作为研究对象，应用常规内镜、NBI及碘染色检查。结果 NBI和碘染色的病变轮廓清晰度基本相同；NBI对低级别黏膜病变的检出率明显低于碘染色；NBI和碘染色分级于低级别黏膜病变均主要为Ⅱ、Ⅲ级，高级别黏膜病变主要为Ⅰ级。结论 NBI可清晰显示早期食管癌的毛细血管结构形态，有机结合NBI技术与碘染色技术可更为有效地提高早期食管癌及癌前病变的诊断率。
