Combined sonographic and radiographic investigations of the biliary duct system using direct percutaneous transhepatic fine needle puncture under constant visualisation and contrast medium demonstration were done in 37 patients. The results show numerous advantages of the method: 1. It is very safe as all tissue and organ areas are under constant surveillance. 2. There is almost no risk of infection. 3. The investigation can be performed on predamaged liver parenchyma. 4. Cytologic material can be obtained; there are no extravasates. The information value of this combined investigation method is greater in a similar group of indications than with radiographic or sonographic methods alone. It appears possible that the risks of ERCP and PTC may be reduced. Further investigations will have to establish the clinical value and risks of this new method.
对37例患者采用直接经皮肝细针穿刺，在持续可视化和造影剂显影下对胆管系统进行超声和放射学联合检查。结果显示该方法具有诸多优点：1. 由于所有组织和器官区域都处于持续监测之下，所以非常安全。2. 几乎没有感染风险。3. 该检查可在受损的肝实质进行。4. 可获取细胞学材料；无外渗情况。在相似的适应证组中，这种联合检查方法的信息价值比单独使用放射学或超声检查方法更大。似乎有可能降低内镜逆行胰胆管造影（ERCP）和经皮肝穿刺胆管造影（PTC）的风险。进一步的研究将确定这种新方法的临床价值和风险。
