Due to the flexibility and an external control mechanism of our thin calibrated cholangioscope (10.2 F) an inspection of the bile ducts via percutaneous transhepatic access is possible without too much discomfort for the patient. A 3.6 F working channel enables target-specific biopsies under optical control. It does not only enable histological diagnosis of the tumour itself but above all the exact definition of the proximal and distal tumour borders. This is a decisive criterion of operability and operation planning especially in tumours of the hepatic bifurcation. Expansion of the compressive lesion may be determined for palliative treatment. Percutaneous stone extraction by contact lithotripsy or with a Dormia basket is technically possible via the working channel under endoscopic view. An inspection of the peripheral branches of the same and the other liver lobe from one access only is made possible by easy maneuverability and flexibility of the endoscope.
由于我们的细校准胆管镜（10.2F）具有灵活性和外部控制机制，经皮经肝途径检查胆管对患者来说不会造成太大不适。3.6F的工作通道可在光学控制下进行靶向活检。它不仅能对肿瘤本身进行组织学诊断，更重要的是能精确界定肿瘤的近端和远端边界。这是可切除性和手术规划的决定性标准，尤其对于肝门部肿瘤。对于姑息治疗，可确定压迫性病变的扩张情况。在内镜观察下，通过工作通道，采用接触碎石术或使用多尔米亚网篮经皮取石在技术上是可行的。内镜的易操作性和灵活性使得仅通过一个入路就能检查同一肝叶和另一肝叶的周边分支。
