摘　　要：目的 :评价肝胆显像和腹部超声检出肝外胆道闭锁 (EHBA)的临床价值。材料和方法 :回顾性分析 119例持续黄疸婴儿肝胆显像和腹部超声检查结果。结果 :肝胆显像检出肝外胆道闭锁的灵敏度 ( 10 0 % )高于腹部超声 ( 79% ) ,以2 4小时内肠道无放射性出现 /未见功能胆囊显影作为EHBA的诊断依据时 ,肝胆显像的特异性可提高至 88% ,但与腹部超声特异性无差异 ,肝胆显像的准确度可提高到 92 % ,高于腹部超声。结论 :肝胆显像检出EHBA的灵敏度高于腹部超声 ,注意观察胆囊显影及其收缩情况可进一步改善其特异性和准确度 ,是临床检出胆道闭锁的首选方法。Purpose: To compare the clinical value of 99m Tc EHIDA hepatobiliary scintigraphy and abdominal ultrasonography in the diagnosis of extrahepatic biliary atresia(EHBA). Materials and Methods: The results of hepatobiliary scintigraphy and abdominal ultrasonography in 119 infants with persistent jaundice were analyzed retrospectively. Results: Hepatobiliary scintigraphy is more sensitive than abdominal ultrasonography in the detection of EHBA(100% vs 79%),With no bowel radioactivity within 24 hours and/or nonvisualization of functioning gallbladders as the diagnostic criterion of EHBA, the specificity for scintigraphic diagnosis of biliary atresia might be increased to 88%, not significantly different with that of abdominal ultrasonography. The accuracy (92%) was significantly higher than ultrasonography. Conclusion: Hepatobiliary scintigraphy was a sensitive diagnostics for biliary atresia.
