超声墨菲征是超声定位胆囊引起的最大压痛，据报道，在经超声检查证实的急性胆囊炎患者中，墨菲征是一个有用的辅助发现。我们评估了200例被认为是急性胆囊炎的右上腹疼痛患者。将超声检查结果及随访结果制成表格。超声墨菲征对急性胆囊炎的敏感性为86%，特异性为35%，阳性预测值为43%，阴性预测值为82%。超声检查包括结石、胆囊壁水肿和胆囊周围积液的敏感性为93%，特异性为53%。墨菲征合并胆结石的特异性为71%。大量的假阳性，当伴有胆结石时，特异性只有适度的改善，使得该征象在区分急性和慢性胆囊炎时不可靠。(C) 1995 John Wiley & Sons, Inc.；
A positive sonographic Murphy sign, the presence of maximal tenderness elicited over a sonographically localized gallbladder, has been reported to be a helpful adjunctive finding in patients with proven acute cholecystitis who are evaluated with ultrasonography. We evaluated 200 patients with right upper quadrant pain, thought to be acute cholecystitis. Results of ultrasound examinations and subsequent follow-up were tabulated. The sensitivity of the sonographic Murphy sign in acute cholecystitis was 86% with a specificity of 35%, positive predictive value of 43%, and negative predictive value of 82%. The sensitivity of the sonographic findings, including stones, gallbladder wall edema, and pericholecystic fluid collections, was 93%, a specificity of 53%. The combination of the Murphy sign accompanied by gallstones yielded a specificity of 71%. The large number of false positives, and only moderate improvement in specificity when accompanied by gallstones, makes this sign unreliable in separating acute from chronic cholecystitis.
