摘要
目的评价超声与CT对急性坏死型胰腺炎(ANP)的诊断价值。方法将42例急性胰腺炎患者手术前超声及CT诊断与手术病理诊断进行对照,分析CT及超声诊断ANP的敏感性、特异性、预测精确性、阳性预测值及阴性预测值。结果CT诊断ANP的阳性预测值94.1%,特异性91.2%,超声诊断ANP的阳性预测值89.3%、特异性84.6%,两者差异无显著性(P>0.05)。CT诊断ANP的敏感性97.6%,阴性预测值70.0%,预测精确性96.17%,超声诊断ANP的敏感性85.7%,阴性预测值27.8%,预测精确性69.0%,两者差异有显著性(P<0.05)。结论超声和CT是诊断ANP的有效方法,超声的特异性和阳性预测值与CT相似,而CT诊断ANP敏感性、阴性预测值、预测精确性优于超声。
Objective:To evaluate the diagnostic accuracy of ultrasonograp hy (US)and computerized tomography(CT)on acute necrosis pancreatitis(ANP).Met hods:The pre-operative diagnoses by US and CTwere compared with surgical and pat hological results in42patients with ANP,and the sensitivity,specificity,posit ive predictive value,predictive accuracy and negative predictive value of US an d CTin the diagnosis of ANP were analysed respectively.Results:The positive pred ictive value and specificity of CTin the diagnosis of ANP were94.1%and91.2%respe ctively,and those of US were89.3%and84.6%,without significant difference betwe en them(P>0.05).The sensitivity,negative predictive value and predictive accu racy of CTin the diagnosis of ANP were97.6%,70.0%and96.1%repectively,and those of US were85.7%,27.8%and69.0%,with significant difference between them(P<0.0 5).Conclusion:Both US and CT are effective methods in the diagnoosis of ANP.The specificity and positive predictive value of US are similar to thos of CT,but t he sensitivity,negative predicitive value and predictive accuracy of CTare supe rior to those of US.
