| 摘 要： | 目的:系统评价CT结肠镜用于结直肠肿瘤和息肉诊断的临床价值。方法:通过计算机检索及手工查阅,全面收集CT结肠镜用于结直肠肿瘤和息肉诊断的中英文文献,按纳入与排除标准筛选文献并提取纳入研究中有关准确度的数据,根据QUADAS条目进行质量评价,采用Me-ta Disc 1.4软件检验研究间的异质性并进行Meta分析。结果:最终纳入英文文献22篇,中文文献0篇。异质性检验结果为Spearman相关系数=0.406,P=0.244,提示阈值效应引起的异质性较小,但是存在其他因素导致的异质性,按随机效应模型进行Meta分析。CTC结肠镜诊断结直肠肿瘤和息肉的敏感度和特异度分别为69%和83%,而且诊断的敏感度和特异度随着肿物大小的增加而增加,分别为62%~81%和90.1%~92.4%。结论:用CT结肠镜诊断结直肠肿瘤和息肉具有很高的特异性,但其敏感度波动范围很大。
