多层螺旋CT与腹部X线平片在诊断急性肠梗阻中的应用比较

Comparison on Application Value between Multi-slice Spiral CT and Abdominal X-ray Plain Film in the Diagnosis of Acute Intestinal Obstruction

目的比较多层螺旋CT(MSCT)与腹部X线平片在诊断急性肠梗阻中的应用价值。方法对164例于我院进行手术及病理检查确诊为急性肠梗阻患者的临床资料,从MSCT与腹部X线平片对急性肠梗阻的检出率及病因等方面综合分析两种检查方法在诊断急性肠梗阻中的应用价值。结果以手术及病理检查结果为金标准:①腹部X线平片对急性肠梗阻患者的诊断准确率为70.12%(115/164),多层螺旋CT对急性肠梗阻患者的诊断准确率为98.17%(161/164),二者诊断准确率比较MSCT高于腹部X线平片(χ^2=48.359,P=0.000)。②腹部X线平片对急性肠梗阻病因确诊率为50.61%(83/164),多层螺旋CT对急性肠梗阻病因确诊率为96.34%(158/164),二者病因确诊率比较MSCT高于腹部X线平片(χ^2=87.995,P=0.000)。结论 MSCT在诊断急性肠梗阻准确性及发病原因方面较腹部X线平片更具优势,能为临床上对疾病的诊断提供更具有指导性的影像学资料,可作为急性肠梗阻患者首选的影像学检查方法。

Objective To compare the application value between multi-slice spiral CT(MSCT) and abdominal X-ray plain film in the diagnosis of acute intestinal obstruction.Methods The clinical value of 164 patients with acute intestinal obstruction diagnosed by surgery and pathological examination in our hospital were collected. The application value of MSCT and abdominal X-ray plain film from the detection rate and pathogenesis of acute intestinal obstruction was comprehensively analyzed. Results The results of surgical and pathological examination were used as the gold standard.①The diagnostic accuracy of abdominal X-ray plain film for acute intestinal obstruction was 70.12%(115/164) and the diagnostic accuracy of multi-slice spiral CT for acute intestinal obstruction was 98.17%.(161/164). The diagnostic accuracy of them was compared. The diagnostic accuracy of MSCT was higher than that of the abdominal X-ray film.(χ~2=48.359, P=0.000).②The diagnostic rates of abdominal X-ray plain film for pathogenesis of acute intestinal obstruction were 50.61%(83/164) and the diagnostic rates of multi-slice spiral CT for pathogenesis of acute intestinal obstruction were 96.34%(158/164). The diagnostic rate of MSCT for pathogenesis of acute intestinal obstruction was higher than that of abdominal X-ray plain film(χ~2=87.995, P=0.000). Conclusion MSCT is superior to abdominal X-ray plain film in the diagnostic accuracy and pathogenesis of acute intestinal obstruction.It can provide more guiding imaging data for clinical diagnosis of diseases, and can be used as the preferred imaging examination for patients with acute intestinal obstruction.
