摘要
目的探讨内镜窄带成像技术(NBI)联合碘染色诊断早期食管癌及癌前期病变的应用价值。方法收集该院2011-03~2016-11行常规内镜、NBI及NBI联合碘染色检查患者的临床资料,筛选其中216例相关病例,比较不同检查方法的检查效果以及NBI、碘染色分级与病理诊断的关系。结果 NBI联合碘染色对病灶的检出率为100.00%,显著高于常规内镜的76.64%和单一NBI检查的89.05%(P<0.05)。高级别瘤变主要表现为NBIⅠ级和碘染色Ⅰ级,低级别瘤变NBI和碘染色主要表现为Ⅱ、Ⅲ级。结论 NBI可清晰显示食管病变毛细血管结构形态,有机结合NBI技术与碘染色技术可有效提高早期食管癌及癌前病变的诊断率。
Objective To investigate the diagnostic value of narrow band imaging（NBI） iodine staining in the patients with early esophageal cancer and precancerous lesions. Methods The clinical data of 216 cases undergo- ing conventional endoscopy, NBI, and NBI combined with iodine staining in our hospital from March 2011 to October 2016 were retrospectively analyzed. The results and the relationship between NBI and iodine staining grading and pathological diagnosis were compared among the different examination methods. Results The detection rate of NBI combined with iodine staining（ 100. 00% ）, was significantly higher than that of the routine endoscopy（76. 64% ） or the single NBI examination（89. 05% ） （P 〈 0. 05）. In the advanced stage, the tumors were mainly expressed as NBI grade Ⅰ and iodine stain grade I , while the lower grade tumors were expressed as grade Ⅱ or grade Ⅲ in the NBI and iodine staining. Conclusion NBI can clearly show the capillary structure of esophageal lesions. Combining NBI with iodine staining can improve the diagnosis rate of early esophageal cancer and precancerous lesions.
