【摘要】 目的 提高内镜下结直肠小息肉的检出率和正确诊断率。方法 经放大电子结肠镜喷洒靛胭脂对123例的直径≤10mm的息肉进行形态和组织学对照研究。结果 靛胭脂喷洒后增生性息肉表面呈规则星状乳头样小窝；腺瘤性息肉表面呈管状或树枝状小窝。经放大肠镜喷洒色素诊断隆起型及扁平型小息肉，总符合率分别为82.0%和77.1%；鉴别腺瘤性息肉与非腺瘤性息肉敏感性和特异性，隆起型小息肉分别为88.4%和92.3%，扁平型小息肉分别为83.3%和90.0%。结论 经放大肠镜喷洒靛胭脂可提高小息肉检出率，较正确判断小息肉性质。

【Abstract】 Objective Thepresent study was aimed at evaluating the chromoscopy in detecting and distinguishingcolorectal minute lesions (polyps).Methods Fujinon EC-410 CM/HLmagnifying endoscope with indigo carmine dye spray was used.Polyps≤10mm in diameter in123 patients were studied morphologically and histologically.Results Theoutlook of stained hyperplastic lesions presented asteroid or papillary dots;that of theadenomatous showed tubular or branched pits .The diagnostic accuracies in macroscopic andmicroscopic views for protruded lesions and flat depressed ones were 82% and 77.1%respectively.While the sensitivity and specificity of the technique to distinguishprotruded and flat adenoma from the non-adenomatous ones being 88.4%,92.3% and 83.3%,90.0%correspondingly.Conclusion With this technique minute polyps could bedetected more frequently and their nature predicted more accurately.
