螺旋CT与腹部X线平片在急性肠梗阻诊断中的应用价值对比分析

Comparative Analysis of the Value of Spiral CT and Abdominal X-ray in the Diagnosis of Acute Intestinal Obstruction

目的:探讨螺旋CT与腹部X线平片在急性肠梗阻诊断中的价值。方法:研究对象为2013年1月~2017年1月期间来某院治疗的疑似肠梗阻患者175例,经病理检查确诊为急性肠梗阻患者155例,均行X线片、CT检查。比较X线片、CT诊断的灵敏度、特异度、准确率;CT诊断的梗阻定位、梗阻原因诊断符合率、假阳性率及假阴性率。结果:螺旋CT定位诊断符合率为92.26%,假阳性率2.58%,假阴性率5.16%;梗阻原因诊断符合率为90.97%,假阳性率为3.23%,假阴性率为5.81%。螺旋CT的灵敏度为96.13%、特异性为90.00%、准确率为95.43%,与X线片比较更高,差异有显著性(P<0.05)。结论:螺旋CT在肠梗阻的定位、梗阻原因均有明显的优势,相较于X线平片,肠梗阻患者用螺旋CT诊断的灵敏度、特异性、准确率均更高,有利于肠梗阻的确诊及治疗方案的选择。

Objective：To evaluate the value of spiral CT and abdominal X-ray in the diagnosis of acute intestinal obstruction.Methods：A total of 175 patients with suspected intestinal obstruction who were treated in a hospital from January 2013 to January 2017 were enrolled in this study.155 patients with acute intestinal obstruction diagnosed by pathology were examined by X-ray and CT.X-ray,CT diagnosis of sensitivity,specificity,accuracy;CT diagnosis of obstruction,obstruction diagnosis of coincidence rate,false positive rate and false negative rate were compared.Results：The coincidence rate of spiral CT was 92.26% ,the false positive rate was 2.58% and the false negative rate was 5.16% .The coincidence rate of obstruction was 90.97% ,the false positive rate was 3.23% and the false negative rate was 5.81% .The sensitivity of spiral CT was 96.13% ,the specificity was 90.00% ,the accuracy rate was 95.43% ,which were higher than those of Xray（P〈0.05）.Conclusion：Spiral CT has obvious advantages in the location of obstruction and obstruction.Compared with X-ray,the sensitivity,specificity and accuracy of spiral CT in patients with intestinal obstruction are higher and is helpful for the diagnosis of intestinal obstruction,and it is conducive to the choice of treatment options.
