正常成人肝外胆管声像图表现的再探讨

Restudy of normal adult's extrahepatic bile duct by ultrasonography

目的:观察正常成人肝外胆管的超声声像图特点,并获取各段肝外胆管内径的超声测值。方法:使用经腹超声扫查胆总管,分别观察肝门段、十二指肠后段、胰腺段胆管等段的走行、毗邻关系等特点,并测量各段肝外胆管的内径。结果:肝外胆管的形状各异,以梭形最常见,其他有蝌蚪形、管形等。肝外胆管内径最宽处位于十二指肠后段,最窄处位于胰腺段。肝门段内径及十二指肠后段内径男性和女性之间的差异无统计学意义,胰腺段内径差异具有统计学意义。结论:掌握肝外胆管的正常声像图特点及其内径的测值,对临床工作有重要参考意义。

Objective：To observe the ultrasonogram of the extrahepatic bile duct in normal adult,and to abtain the value of its inner diameter. Methods：The trace,adjacent relationship of hepatic hilum duct（HHD）,retroduodenal duct（RDD） and duct in pancreas（DP） were detected respectively by using transabdominal ultrasonography. Their inner diameters were measured in ultrasonogram. Results：The extrahepatic duct come in a variety shapes,but the spindle-like was the most common,and more shapes included the tadpole-like and the tube-like. The differences of HHD and RDD were not markedly significant between male and female,however DP＇s difference had significance between male and female. Conclusion：The acoustic imaging of the extrahepatic bile duct and the parameter of their inner diameter obtained in this research have important reference significance in clinical work.
