多层螺旋CT在诊断小肠不明原因出血的价值

Value of Multi Slice Spiral CT in the Diagnosis of Small Intestinal Bleeding with Unknown Cause

目的:比较多层螺旋CT与气钡双重造影在诊断小肠不明原因出血中的临床价值。方法:选取经病理或随访确诊小肠病变32例患者为研究对象,分别采用多层螺旋CT(MSCT)及气钡双重造影检查,比较两者检查结果。结果:MSCT检出率明显高于气钡双重造影(81.25%VS 65.25%),差异有统计学意义(χ2=4.25,P<0.05)。结论:MSCT在小肠不明原因出血诊断中有一定比较优势,MSCT检查较气钡双重造影有利于提高诊断准确率。

Objective:To compare the clinical value of spiral CT and multi air barium double contrast radiography in the diagnosis of small intestinal bleeding with unknown causes.Methods:32patients diagnosed with small bowel disease by pathology or follow-up were selected as the research objects,respectively received multi-slice spiral CT(MSCT)and air barium double contrast examination,examination results were compared.Results:The positive rate of MSCT was higher than that of air barium double contrast radiography(81.25% VS 65.25%),the difference was statistically significant(χ~2=4.25,P<0.05).Conclusion:There is certain comparison superiority for MSCT diagnosis in small intestinal bleeding with unknown causes,it is helpful to improve the diagnosis accuracy rate compared with air barium double contrast examination.
