摘要

超声检查是胆道闭锁(BA)诊断过程中的重要组成部分。BA的特征性表现包括肺门高回声区、三角索征(TCS)、进食后胆囊无收缩和胆囊萎缩。然而,大约10%的BA患者胆囊正常。本文报告两例胆囊形态正常的BA,如超声所示。在第一例中,患者TCS呈阳性,胆囊萎缩呈阴性,进食后胆囊收缩呈阳性;最终诊断为肝门梗阻性BA合并胰胆管连接不良。在第二个病例中,患者TCS呈阳性,胆囊萎缩呈阴性,进食后胆囊收缩呈阴性;患者还存在肝门区总胆管梗阻和肝管狭窄。基于这两个病例,我们得出结论,胆囊的检查结果不能诊断BA,因为在某些类型的胆囊中,胆囊的形态可能正常,甚至在进食后有收缩的能力。

Diagnostic Significance of Absence of Post-Feeding Contraction of the Gallbladder in Biliary Atresia: Two Case Reports.

Ultrasonography is an essential part of the diagnostic process of biliary atresia (BA). The characteristic findings of BA include a hilar hyperechoic zone, the triangular cord sign (TCS), an absence of gallbladder contraction after feeding, and gallbladder atrophy. However, approximately 10% of patients with BA have a normal gallbladder. We herein present two cases of BA with normal morphology of the gallbladder as shown by ultrasonography. In the first case, the patient was positive for the TCS, negative for gallbladder atrophy, and positive for contraction of the gallbladder after feeding; the final diagnosis was hilar obstructive BA complicated by pancreaticobiliary maljunction. In the second case, the patient was positive for the TCS, negative for gallbladder atrophy, and negative for contraction of the gallbladder after feeding; the patient also had common bile duct obstruction and stenosis of the hepatic duct in the hilar region. Based on these two cases, we conclude that gallbladder findings are not diagnostic for BA because in some types, the gallbladder may be normal in morphology and even have the capacity for contraction after feeding.
