目的探讨CT在诊断结肠癌致肠梗阻患者中的临床价值。方法选取2015年1月至2016年1月沈阳市红十字会医院收治的108例结肠癌致肠梗阻患者作为研究对象,按照随机数字表法将其分为CT组与X射线组,各54例。比较两组患者诊断准确率、病因检出率与直接征象、间接征象检查结果等。结果 CT组患者诊断符合率明显高于X射线组,差异有统计学意义(χ~2=12.65,P<0.05);CT组病因检出率明显高于X射线组,差异有统计学意义(χ~2=9.57,P=0.001);CT组狭窄段、侵犯周围脏器组织、狭窄段与正常肠管交界处改变等直接征象及盲肠扩张、缺血性结肠炎、结肠梗阻表现等间接征象的检出率均明显高于X射线组,差异均有统计学意义(均P<0.05)。结论在结肠癌致肠梗阻患者的临床诊断中,CT有着较X射线更为显著的效果,能提升诊断符合率和病因检出率,且直接征象、间接征象的检出率较高。
Objective To investigate the clinical value of CT in the diagnosis of intestinal obstruction caused by colon cancer. Methods From January 2015 to January 2016, Shenyang Red Cross Hospital, 108 cases of colon cancer caused by intestinal obstruction patients were divided into CT group and X-ray group according to random number table method, each 54 cases . The diagnostic accuracy rate, the detection rate of the cause and the direct signs, the results of the indirect signs were compared between the two groups. Results The diagnostic coincidence rate of CT group was significantly higher than that of X-ray group (χ ~ 2 = 12.65, P <0.05). The detection rate of CT in the CT group was significantly higher than that of the X-ray group χ ~ 2 = 9.57, P = 0.001) .There were direct signs such as stenosis in CT group, infiltrating organs and tissues around the stenosis, changes in the junction of stenosis and normal intestine, indirect signs such as dilatation of caecum, ischemic colitis and colonic obstruction The detection rate was significantly higher than the X-ray group, the differences were statistically significant (P <0.05). Conclusion In the clinical diagnosis of intestinal obstruction caused by colon cancer, CT has a more significant effect than X-ray, which can improve the diagnostic coincidence rate and the detection rate of the cause, and the direct signs and indirect signs are higher.
