We studied by ultrasound (U.S.) a diagnostic method, 87 cases with probable pancreatic cancer; 29 were confirmed surgically. We found an accurate diagnosis in 93.1% of the cases with 6.89% of false negatives and 19.54% of false positives. Likewise, 2.29% of the patients could not be explored by U.S. because they had important meteorism. Among the false positive cases the most important differential diagnosis for us was Chronic Pancreatitis. We conclude that U.S. is a certainly, high sensitive, specific, non invasive and not expensive method. Hence, for us, U.S. is one of the first diagnostic method that must be used when pancreatic neoplasm is suspected.
我们采用超声（U.S.）这种诊断方法对87例疑似胰腺癌患者进行了研究；其中29例经手术确诊。我们发现该方法诊断准确率为93.1%，假阴性率为6.89%，假阳性率为19.54%。同样，2.29%的患者因严重腹胀而无法接受超声检查。在假阳性病例中，对我们来说最重要的鉴别诊断是慢性胰腺炎。我们得出结论，超声是一种确定的、高灵敏度、高特异性、非侵入性且成本不高的方法。因此，对我们而言，超声是怀疑胰腺肿瘤时首先必须使用的诊断方法之一。
