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。
Objective The
present study was aimed at evaluating the chromoscopy in detecting and distinguishing
colorectal minute lesions (polyps). Methods Fujinon EC410 CM/HL magnifying endoscope with
indigo carmine dye spray was used.Polyps10mm in diameter in 123 patients were studied
morphologically and histologically. Results The outlook of stained hyperplastic lesions
presented asteroid or papillary dots;that of the adenomatous showed tubular or branched pits
.The diagnostic accuracies in macroscopic and microscopic views for protruded lesions and flat
depressed ones were 82% and 77.1% respectively.While the sensitivity and specificity of the
technique to distinguish protruded and flat adenoma from the nonadenomatous ones being
88.4%,92.3% and 83.3%,90.0% correspondingly. Conclusion With this technique minute polyps
could be detected more frequently and their nature predicted more accurately.
