内镜窄带成像技术结合染色内镜在早期食管癌诊断中的临床应用

Clinical application of endoscopic narrow band imaging combining staining endoscopy in diagnosing early esophageal carcinoma

目的:比较内镜窄带成像技术(NBI),结合碘染色和单纯碘染色在早期食管癌的诊断价值。方法:选取我院收治的100例疑似早期食管癌患者为研究对象,随机分为2组,A组给予常规碘染色检查,B组给予NBI结合碘染色,分析2种检查方法对患者病变区域的检出率以及单独使用碘染和NBI染色对病变边缘清晰度比较。结果:单纯碘染与NBI检查病变轮廓清晰度比较2分、4分有统计学意义(P<0.05);癌变部位的早期检出中NBI结合染色内镜检查与染色内镜检查有统计学意义(P<0.05)。结论:NBI染色内镜具有操作方便、图像清晰、检出率高等优点,值得在早期食管癌诊断中进行推广与应用。

Objective： To compare the diagnostic value of endoscopic narrow band imaging NBI combined with iodine staining and single iodine staining for early esophageal cancer. Methods： One hundred patients suspected to suffer from early esophageal cancer were enrolled and randomly divided into two groups,patients in group A were subjected to conventional iodine staining endoscopy,and patients in group B were subjected to NBI combining iodine staining endoscopy. The cancer detection rates of two groups were analyzed,and the distinctness of lesion margins were compared as well. Results： The edge sharpness of lesions demonstrated by single staining and NBI were 2 scores and 4 scores respectively,with statistical significance（ P 〈0. 05）. The difference between NBI combining staining endoscopy and conventional staining endoscopy in early detection on the location of cancer was also statistically significant（ P〈0. 05）. Conclusions： NBI endoscopy is easy to operate,gives clear image and with high cancer detection rate. It is worthy to recommend for application in the diagnosis of early esophageal cancer.
