目的：探讨高清窄带成像内镜（ NBI）及色素内镜对大肠肿瘤的诊断价值。方法常规结肠镜检出大肠息肉86枚，应用高清窄带内镜观察其黏膜表面毛细血管形态（CP）和色素内镜观察腺管开口类型（PP），预测息肉的类型，并与病理组织学进行对照研究。结果高清窄带成像内镜对大肠肿瘤的诊断敏感度为81．1％，特异度为78．8％，准确度为80．2％，阳性预测值为86．0％，阴性预测值为72．2％。色素内镜对大肠肿瘤的诊断敏感度为83．0％，特异度为84．8％及准确度为83．7％，阳性预测率为89．8％，阴性预测率为75．7％。两者对大肠肿瘤诊断敏感度、特异度及准确度比较均无显著性差异（P＞0．05）。结论应用高清窄带成像内镜及色素内镜，均能高度准确预测大肠肿瘤的病理类型，具有良好的临床应用价值。

Objective To study the diagnostic value of high definition narrow -band imaging endoscopy and chromoen-doscopy for colonic neoplasm .Methods 86 colonic polypus were discovered by conventional colonoscopy .The capillary pattern was observed by high definition narrow -band imaging endoscopy and pit pattern was observed by chromoendoscopy ,to study the relation of the capillary pattern and pit pattern with histopathology .Results The diagnostic accuracy rate of high definition nar-row -band imaging endoscopy was 80.2%,sensitivity was 81.1%,specificity was 78.8%,positive predictive value was 86.0%, negative predictive value was 72.2%.The diagnostic accuracy rate of chromoendoscopy was 83.7%,sensitivity was 83.0%,spe-cificity was 84.8%,positive predictive value was 89.8%,negative predictive value was 75.7%.There had no significant differ-ence between the 2 methods(P>0.05).Conclusion High definition narrow-band imaging endoscopy and chromoendoscopy can effectively predict pathology of colonic neoplasm ,and they have good clinical application .
