翻译：肝内胆管右后支置入PTCD引流后胆汁引流不通畅胆红素下降不明显；我们来看看常规超声显示引流管在腹壁与肝脏之间走形有折叠那是因为折叠导致的胆汁引流不畅嘛？ICCEUS显示引流管在腹壁与肝脏之间走形扭曲未在胆管内明确了胆汁引流不畅的原因。

After the right posterior branch of the intrahepatic bile duct was inserted with PTCD drainage, bile drainage was not smooth and bilirubin did not decrease significantly. Let's take a look at the conventional ultrasound, which shows that the drainage tube is folded between the abdominal wall and the liver, causing poor bile drainage. Is it due to the folding? ICCEUS shows that the drainage tube is twisted and distorted between the abdominal wall and the liver, not inside the bile duct, which clearly identifies the cause of poor bile drainage
