超声造影对急性重症胰腺炎的诊断价值初探

目的 探讨超声造影对急性重症胰腺炎的诊断准确性.方法 以增强CT结果为金标准,对33例72 h内已行增强螺旋CT检查的急性胰腺炎患者进行实时超声造影,分析其对急性重症胰腺炎的诊断价值.结果 超声造影诊断胰腺实质内坏死灶的敏感性、特异性、准确性、阳性预测值、阴性预测值分别为90%、95%、94%、90%和95%;超声造影诊断急性重症胰腺炎的敏感性、特异性、准确性、阳性预测值,阴性预测值分别为85%、92%、88%、94%和80%,而常规超声诊断急性重症咦腺炎的敏感性、特异性、准确性、阳性预测值、阴性预测值分别为37%、86%、58%、78%和50%.结论 超声造影对咦腺内坏死灶及急性重症胰腺炎的诊断准确性较高.

Preliminary study in detecting acute severe pancreatitis with contrast enhanced ultrasound

Objective To investigate the accuracy of contrast enhanced ultrasound (CEUS) in diagnosing acute severe panereatitis.Methods Thirty three patients with acute severe pancreatitis were enrolled in the study and all of them underwent CEUS and spiral computed tomography(CT) scan.CT was taken as gold standard in acute severe pancreatitis diagnosis.CEUS were done within 72 hours after CT scan.Results Compared with CT, the sensitivity, specificity,accuracy, positive predictive value,and negative predictive value of CEUS for detecting the necrosis of pancreas were 90%, 95%, 94%, 90% and 95%respectively.The sensitivity, specificity, accuracy, positive predictive value,and negative predictive value of CEUS in diagnosing severe acute pancreatitis were 85%, 92%, 88%, 94% and 80% respectively, while 37% ,86% ,58%, 78%, 50% for conventional ultrasound respectively.Conclusions CEUS is accurate in detection of pancreatic necrosis and diagnosis of acute severe pancreatitis.
