本文旨在评价结肠镜对炎性结肠病(IBD)诊断的准确性,内镜象的敏感性和特异性,并从中推出一种客观又实用的“内镜计分”。作者将IBD的常见内镜象、病程、病变活动性及镜检深度制成分析卡片;并根据内镜象将诊断分为克隆氏病(CD)、溃疡性结肠炎(UC)及未能确定类型的IBD三类。随访结束时,将以在诊断CD或UC的内镜所见输入计算机作资料分析,并用X~2检验的联列表分析内镜特征。选择最有单独预示价值的变数,计算出内镜特征的敏感性、特异性和预示值,再评价内镜象的诊断准确性。本组共357例患者,内镜检查606次。内镜检查
This article aims to evaluate the diagnostic accuracy of colonoscopy for inflammatory bowel disease (IBD), the sensitivity and specificity of endoscopic imaging, and to develop an objective and practical “endoscopic score.” The author made the analysis of common endoscopy, course of disease, pathological activity, and the depth of microscopic examination of IBD. The diagnosis was divided into Crohn’s disease (CD), ulcerative colitis (UC) according to endoscopy and failed to determine Three types of IBDs. At the end of the follow-up visit, data from the endoscopic findings on the diagnostic CD or UC were entered into the data analysis and endoscopic features were analyzed using a cohort of X-2 tests. The variables with the most individual predictive value were chosen to calculate the sensitivity, specificity, and predictive value of endoscopic features, and the diagnostic accuracy of endoscopic imaging was evaluated. A total of 357 patients in this group, 606 endoscopy. Endoscopy
