2、镜发现隆起样病变的敏感性为80.0%(80/103),切换NBI后,能清楚显示隆起样病变的形态和边界,发现隆起样病变的敏感性为100%(103/103);NBI普通内镜观察隆起样病变腺管开口,根据工藤进英腺管开口形态分型法进行诊断,其中腺管开口呈Ⅱ型18例,Ⅲ(L)型54例,Ⅳ型15例,V型16例。NBI普通内镜对于大肠隆起性病变肿瘤及非肿瘤性的鉴别诊断的敏感性、特异性分别为95.3%(81/85)、83.3%(15/18)、NBI普通内镜对于大肠隆起性病变肿瘤及非肿瘤性的鉴别诊断的符合率为93.2%(
3、96/103),与文献报道的NBI放大内镜的94.1%无统计学差异(P>0.05)。结论应用NBI普通内镜,也可以通过观察腺管开口形态,比较准确地鉴别诊断大肠肿瘤与非肿瘤病变。【关键词】结肠镜检查;窄带成像技术;大肠隆起病变;腺管开口Narrow-bandimagingwithroutineendoscopyindiagnosisofcolorectalprotrudinglesionsWangYi,CuiXu,Jianhua,XuDan,CyuDongyue.DepartmentofGastroent
