摘要
目的 评价超声及 CT诊断急性坏死型胰腺炎 ( ANP)的价值。方法 将 3 8例急性胰腺炎患者手术前的超声及 CT诊断资料与手术病理诊断进行对照 ,分析超声及 CT诊断 ANP的敏感性、特异性、预测精确性。结果 3 8例患者 ,按手术病理诊断 ,3 0例为ANP,7例为急性水肿型胰腺炎 ,1例化脓性胆囊炎胰腺未见异常。 CT诊断 ANP的敏感性 95 .8% ,特异性 80 .0 % ,阳性预测值95 .8% ,阴性预测值 80 .0 % ,预测精确性 93 .1%。 B超诊断 ANP的敏感性 69.0 % ,特异性 60 .0 % ,阳性预测值 90 .9% ,阴性预测值2 5 .0 % ,预测精确性 67.6%。结论 B超和 CT是诊断 ANP的有效方法 ,B超的特异性和阳性预测值与 CT相似 ,敏感性、阴性预测值、预测精确性不如 CT,在应用 B超诊断 ANP时 ,必须密切结合临床体征和 CT检查。
Objective To evaluate the diagnostic accuracy of B mode ultrasonography (US) and computerized tomography (CT) for acute necrosis pancreatitis (ANP). Method The pre-operation diagnoses by US and CT were compared with the surgical and pathological results in 38 patients with clinically diagnostic acute pancreatitis, and the sensitivity, specificity, predictive accuracy of US and CT in the diagnosis of ANP were analysed. Result According to surgical and pathological findings, 30 cases were diagnosed as ANP, 7 as acute minor pancreatitis, and 1 as acute suppurant cholecystitis with normal pancreas. The sensitivity, specificity, positive predictive value, negative predictive value and predictive accuracy of US in diagnosis of ANP were 69.0%, 60.0%, 90.9%, 25.0%, 67.6%, and those of CT were 95.8%, 80.0%, 95.5%, 80.0%, 93.1% respectively. Conclusion Both US and CT are useful diagnostic methods for ANP. The specificity and positive predictive value of US are similar to that of CT. The sensitivity, negative predictive value and predictive accuracy of US are worse than those of CT. When US is used for diagnosis of ANP, it should be noted that the clinical data and CT characteristics of patient must be considered.
