| ［摘要］ 目的 探讨超声诊断壶腹癌的准确性以及其与胰头癌、胆管下段癌的鉴别。方法 对2007-02～2009-01收治的壶腹周围癌患者采用回顾性分析的方法进行统计学分析。结果 54例病例超声诊断平均准确率为87.04%。三组肿瘤最大直径的比例进行组间比较（χ2=13.41，P<0.05）肿瘤直径差异有统计学意义；胰头癌组、壶腹癌组差异有统计学意义（P<0.01）。肝外胆管扩张程度，壶腹癌组和胆总管下段癌组分别与胰头癌组差异有统计学意义（P<0.05），胰管扩张程度三组差异无统计学意义（P>0.05）。结论 超声诊断是壶腹癌最重要的诊断手段，对鉴别胰头癌和胆管下段癌有辅助作用。 |

| Abstract: |
| ［Abstract］ Objective To probe the accuracy of ultrasound diagnosis of carcinoma in ampulla of vater(CAV), and the differentiation between carcinoma of head of pancreas(CHP) and carcinoma of bile duct(CBD). Methods Retrospective review of 54 patients sufering from periampullary carcinoma from 2007 to 2009 was performed.Results The ultrasonography results of 54 patients of periampullary carcinoma accorded with operation pathological results with accuracy of 87.04% on average.The differences in longest diamieters of cacinomas between CAV、CHP and CBD were remarkable(P<0.05), significant difference between CAV and CHP (P<0.01). Prominent differences between CAV、CBD and CHP existed in the ratio of dilation of the exrahepaticbihe duct（P<0.05）.The ratio of dilation of ductus pancreaticus were not markedly different respectively.Conclusion The ultrasound is the chief diagnostic method of carcinoma in ampulla of vater and is helpful to differentlal diagnosis between CAV, CHP and CBD. |
