目的研究CT检查对结肠癌所致肠梗阻诊断的准确性,探讨其临床应用的价值。方法回顾性分析我院2013年4月~2014年3月肛肠外科收治因结肠癌致肠梗阻的患者50例,均经手术病理检测确诊病情。分析患者术前CT检查和腹部X线平片检查结果,对比研究两种检查结果对结肠癌致肠梗阻诊断的正确率。结果CT诊断肠梗阻46例,确诊率92%,X线平片为32例,确诊率64%,两者比较,CT的诊出率显著高于X线平片诊断,差异有统计学意义(P<0.05);CT诊出病因为结肠癌有50例,占100%,X线平片诊出6例,占12%,两种方式对病因的检出率比较差异有统计学意义(P<0.05)。结论螺旋CT检查诊断结肠癌致肠梗阻的准确率高,能为临床治疗提供可靠的参考依据,值得关注。
Objective To study the accuracy of CT examination in the diagnosis of intestinal obstruction caused by colon cancer and to explore the value of its clinical application. Methods Retrospective analysis of 50 cases of intestinal obstruction caused by colon cancer in our department from April 2013 to March 2014 in our hospital were analyzed retrospectively. Analysis of preoperative CT and abdominal plain film X-ray examination results, comparative study of two test results on colon cancer caused by intestinal obstruction diagnostic accuracy. Results CT diagnosis of intestinal obstruction in 46 cases, the diagnosis rate was 92%, X-ray film was 32 cases, the diagnosis rate was 64%, the two were compared, the CT diagnosis rate was significantly higher than the X-ray diagnosis, the difference was statistically significant P <0.05). CT diagnosis of colon cancer due to 50 cases, accounting for 100%, X-ray 6 cases, accounting for 12%, the two methods of detection of the cause of the difference was statistically significant (P <0.05). Conclusion The accuracy of helical CT in diagnosing colon obstruction is high, which can provide a reliable reference for clinical treatment.
