【摘要】 本文分析了经手术、病理或其他检查证实的胰腺及其周围肿块47例的实时B型超声图象。超声诊断胰腺癌符合率,胰头癌15/18、胰体(尾)癌8/12、乏特氏壶腹及乳头癌11/17,误诊10例,漏诊3例。10例误诊中,定性错误及定位错误各4例(各8.5％),误诊为胆管结石2例(4.3％)。3例漏诊均为乏特氏壶腹及乳头癌,超声检查仅发现肝外胆管下段梗阻。作者认为,上述误诊除了与超声仪器性能、患者腹壁透声状况和肿块与周围粘连程度有关外,在很大程度上与检查者的经验和检查方法有关。更多还原

【Abstract】 In this paper,the real-time B-mode sonogram of 47 cases of pancreatic and peripancreatic masses proved by surgical,pathological or other examinations were analysed,and the causes of misdiagnosis were discussed.The diagnostic accuracy was 15/18 in pancreatic head carcinoma,8/12 in the body or tail,and 11/17 in the ampulla and papilla,,In the 10 misdiagnosed eases,4 were misjudged in the nature and 4 were mislocated and the rest 2 were misdiagnosed as cholelith.All the 3 nondiagnosed cases were carcinoma of ampulla and papilla,they appeared with cholangiectasis on the ultrasonogram,no pancreatic mass could be discovered.The authers considered that the causes of misdiagnosis were more closely corelated with the experience of the examiners and their scanning method,although the quality of the ultrasound scanner,the accustic condition of abdomen and the adhesive condition around the masses could take part as well.更多还原
