摘　　要：目的探讨剪切波弹性成像(SWE)在胆道闭锁患儿术后早期胆管炎诊断中的临床价值。方法选取我院经手术病理证实的胆道闭锁患儿59例,根据患儿术后1个月内是否出现胆管炎,分为胆管炎组23例及非胆管炎组36例,SWE测量两组术前及术后1个月患儿肝杨氏模量平均值(Emean),比较两组内及组间术前及术后1个月肝Emean值变化情况。分析肝Emean值与患儿年龄间的关系。结果两组术前与术后1个月肝Emean值比较差异均有统计学意义(均P<0.05);术前胆管炎组与非胆管炎组肝Emean值比较差异无统计学意义的情况下,术后1个月胆管炎组肝Emean值明显高于非胆管炎组[(18.42±7.74)kPa vs.(12.68±4.99)kPa],差异有统计学意义(t=-3.477,P=0.001)。所有患儿年龄与术前肝Emean值呈弱正相关(r=0.258,P=0.000),但与术后1个月肝Emean值无相关性。结论SWE技术在胆道闭锁患儿术后早期筛检胆管炎中具有一定的临床价值。Objective To investigate the diagnostic value of shear wave elastography(SWE)in early postoperative cholangitis in children with biliary atresia.Methods Fifty-nine children who were diagnosed with biliary atresia in our hospital and confirmed by operation were analyzed.In addition,1 month after operation infants were divided into cholangitis group(n=23)and non-cholangitis group(n=36)according to whether cholangitis occurred,the preoperative and one-month postoperative changes of liver mean Young’s modulus(Emean)in the two groups of SWE were measured and compared.Results There was a statistically significant difference of preoperative and postoperative liver Emean values between the non-cholangitis group and the cholangitis group respectively(both P<0.05).When the comparison of preoperative liver Emean was not statistically significantin between the cholangitis group and non-cholangitis group.The liver Emean of cholangitis group was significantly higher than that of the non-cholangitis group after operation in 1 month[(18.42±7.74)kPa vs.(12.68±4.99)kPa],there was significant difference(t=-3.477,P=0.001).The preoperative liver Emean values of all infants showed a linear relationship with the age(r=0.258,P=0.000).However,there was no significant linear correlation between the age and the liver Emean after operation in 1 month.Conclusion SWE technique has certain value in the detection of liver stiffness in infants with biliary atresia in early cholangitis.
