1、结肠癌致肠梗阻的CT诊断•肿瘤医学论文结肠癌致肠梗阻的CT诊断刘汉武周智群林蓬春汕头市澄海区人民医院CT室，广东汕头515800［摘要］目的探讨CT诊断对结肠癌致肠梗阻的准确率，分析其临床价值。方法选择2011年1月一2012年1月该院肛肠夕卜科收治的150例结肠癌致肠梗阻病人作为该研究的观察对象。均经手术病理检测确诊病情。全部病人术前都给予CT和X线平片检查，术后将影像资料与病理结果进行分析，对照两种方式诊断正确率的高低。结果CT扫描诊断为肠梗阻的准确率是92.67%(139/150),X线平片准确率是64

2、.67%(97/150),CT扫描对肠梗阻的检出率显著高于X线平片(P<0.05)。CT查出病因是结肠癌的概率为100%zX线为12.37%(12/97X两种方式对肠梗阻的病因检出率比较，差异有统计学意义(P<0.05L结论CT检查对结肠癌致肠梗阻具有较高的检出率，且能查出病因、病灶部位、梗阻程度等,为临床治疗提供较可靠的依据。关键词结肠癌致肠梗阻；CT诊断；X线平片诊断；征象;病因［中图分类号］R574.12［文献标识码］A［文章编号］1674-0742(2014)06(c)-0007-03CTDiagno
