摘　　要：目的探讨超声在先天性囊肿型胆道闭锁和胆总管囊肿鉴别诊断中的价值。方法回顾性分析超声发现肝门区的囊肿并接受手术治疗的患儿53例,根据手术结果分为闭锁组和胆囊肿组,总结两组超声的特点,比较两组观测指标的差异。结果闭锁组囊肿的体积(2.55±2.31)cm^3,明显小于胆总管囊肿组(56.06±101.79)cm^3(t=3.482,P=0.01)。闭锁组胆囊收缩功能不良率(89%),明显高于胆总管囊肿组(2.6%);闭锁组肝门部纤维块发生率(77%),明显高于胆总管囊肿组(0%);闭锁组肝内胆管扩张发生率、囊肿内胆泥沉积率低于胆总管囊肿组。结论超声发现婴儿肝门区囊肿,可根据囊肿的体积、壁厚、胆囊收缩功能、肝内胆管扩张等鉴别诊断。Objective To investigate the value of ultrasound in the differential diagnosis of congenital cystic biliary atresia and choledochal cyst.Methods Retrospectively analyzing of 53 patients who were found hepatic portal cystic lesions in ultrasonography and have received surgical treatment.According to surgery results,it was divided into the atresia group and the cyst group.Summarized the ultrasonic characteristics of the two groups to find out the differences between the two groups.Results The volume of cyst in the atresia group（2.55±2.31）cm^3 was significantly smaller in the cyst group（56.06±101.79）cm^3.The contractibility of gallbladder dysfunction rate（89%）and the liver portal fiber block occurrence rate（77%）of atresia group were significantly higher than those in the cyst group（26% and 0%,respectively）.Intrahepatic bile duct dilatation occurred rate,cyst bladder mud sedimentation of atresia group were significantly lower than those of cyst group.Conclusions We can differentiate congenital cystic biliary atresia with choledochal cyst on the basis of the cyst volume,shape,wall,gallbladder contraction function,intrahepatic bile duct dilatation by ultrasonography.
