摘　　要：目的分析婴儿胆道闭锁(Biliary Atresia,BA)的相关超声测量参数,探讨其诊断价值。方法回顾性分析2015年10月至2017年10月我院手术及病理确诊的BA患儿78例作为病例组,同时选取同期婴儿肝炎综合征(简称婴肝)患儿81例作为对照组。记录两组超声图像及参数:胆囊大小与形态(X1)、肝门部纤维块厚度(X2)、门静脉主干内径(X3)、脾门处脾静脉内径(X4)、肝右叶肋下长度(X5)、脾肋下长度(X6)、肝脏硬度值(弹性模量值,X7)。采用Logistic回归分析法分析以上所测得参数与BA的相关性及相关性大小。结果回归方程显示,X1、X2、X7三项参数对BA的诊断价值较大。结论二分类Logistic回归模型的建立能够筛选出对BA的诊断有意义的超声测量参数,有利于BA与婴肝的超声鉴别诊断,为临床提供帮助。Objective To analyze infant biliary atresia(BA) related ultrasound measurement parameter for its diagnostic value. Methods A retrospective analysis was made on 78 cases of BA diagnosed by operation and pathology in our hospital from October 2015 to October 2017. At the same time, 81 cases of infant hepatitis syndrome(abbreviated as infant liver) were selected as control group. Ultrasound images of the two groups and the following parameters were recorded: gallbladder size and shape(X1), porta fibers thickness(X2), main portal vein inner diameter(X3), inner diameter of splenic vein at splenic hilum(X4), subcostal length of right lobe of liver(X5), subcostal length of spleen(X6), hepatic stiffness(modulus of elasticity, X7). Logistic regression analysis was used to analyze the correlation between the parameters measured above and biliary atresia. Results The regression equation showed that X1, X2 and X7 were of great diagnostic value for BA. Conclusion The establishment of binary Logistic regression model can screen out the ultrasonic measurement parameters that are meaningful for the diagnosis of BA, which is conducive to the ultrasonic diagnosis of BA and infant hepatitis syndrome, and provides help for clinical practice.
