翻译：小结CEUS在胆管疾病中的应用价值通过前面的讲解接下来我们总结下ICCEUS在胆管系统中的应用价值首先相比常规超声ICCEUS能更清晰的显示引流管位置及尖端评估引流管是否在胆管腔内；ICCEUS能显著提高对梗阻性黄疸的梗阻部位及狭窄程度的诊断从而实时优化PTCD的置管策略并有助于肝门胆管癌的分型；能够及时发现相关并发症等

Summary, the application value of CEUS in biliary tract diseases Based on the previous explanations, we can now summarize the application value of ICCEUS in the biliary tract system. Firstly, compared to conventional ultrasound, ICCEUS can provide clearer visualization of the position and tip of the drainage tube, allowing for evaluation of whether the drainage tube is within the bile duct lumen. ICCEUS can significantly improve the diagnosis of the site and degree of obstruction in obstructive jaundice, thus optimizing the PTCD placement strategy in real-time and aiding in the classification of hilar cholangiocarcinoma. It can also timely detect relevant complications, etc
