目的探讨胆道超声造影在经皮经肝胆道穿刺引流术(PTCD)后引流不畅患者中的应用价值。方法 27例PTCD术后胆汁引流不畅的患者经PTCD引流管注入造影剂(1∶30稀释的SonoVue)行超声造影检查,观察引流管是否位于胆管内、引流管末端位置以及引流范围。结果胆道超声造影判断引流管是否位于胆管内的准确度和对引流管末端的显示率分别为100%、100%,优于常规超声37.0%和14.8%(P<0.001)。结论胆道超声造影能够准确的显示引流管走形及末端位置,效果明显优于常规超声,并可评估引流范围,对判断PTCD术后患者引流不畅的原因有着重要的临床意义。
Objective To explore the value of contrast echocardiography in patients with poor drainage after percutaneous transhepatic biliary drainage (PTCD). Methods Twenty-seven patients with poor biliary drainage after PTCD were enrolled in the contrast medium (1: 30 dilution SonoVue) through the PTCD drainage tube to observe whether the drainage tube was located in the bile duct, the distal end of the drainage tube and the drainage area. Results The accuracy of biliary ultrasonography in determining whether the drainage tube was located in the bile ducts and the indication rate of the end of the drainage tube were 100% and 100% respectively, which was better than 37.0% and 14.8% of the conventional ultrasound (P <0.001). Conclusions Biliary ultrasonography can accurately show the shape and location of the drainage tube. The effect is better than that of conventional ultrasound and can evaluate the drainage range. It is of great clinical significance to determine the cause of poor drainage in patients after PTCD.
