窄带成像技术普通内镜诊断大肠肿瘤的价值

摘要

目的 探讨窄带成像技术普通内镜(NBI)诊断大肠肿瘤的临床价值.方法 2012 年6 月至2012 年8 月行常规内镜和NBI 普通内镜检查的患者225 例,对发现的大肠新生性病变记录腺管开口形态,将NBI 内镜诊断和病理组织学诊断结果进行对比分析,并比较NBI 内镜与常规内镜在鉴别肿瘤性和非肿瘤性病变的敏感性、特异性和准确性.结果 NBI 普通内镜对腺管开口类型的判断接近病理水平,鉴别病变是否为肿瘤的敏感性、特异性、准确率分别为93.6%,91.7%和93.0%,显著高于常规内镜(P <0.01).结论 NBI 普通内镜能较准确判断病变的性质,为鉴别是否为肿瘤性病变的更有效的内镜方法.%Objective To evaluate the clinical value of narrow-band imaging(NBI) in diagnosis of colorectal neoplasm. Methods Two hundred and twenty-five patients with colorectal lesions detected by conventional endoscopy and NBI routine endoscopy from June to August, 2012 were enrolled in the study. The lesions were classified by pit pattern which was compared with the results of histopathology, and the sensitivity, specificity and accuracy of conventional endoscopy and NBI routine endoscopy was calculated to distinguish neoplasm from non-neoplasm. Results Pit pattern identified by NBI routine endoscopy closely corresponded to histopathology. The diagnostic sensitivity, specificity and accuracy for neoplasm were 93.6%, 91.7%, and 93.0%, respectively, which was significantly higher than conventional endoscopy. Conclusion NBI routine endoscopy can be applied to diagnose colorectal lesions, which is an new useful technology for detection of colorectal neoplasm.
