In 44 patients with biliary obstructions, percutaneous transhepatic cholangioscopy (PTCS) was performed during percutaneous transhepatic biliary drainage procedures (PTCD). In all patients the obstruction could be decompressed via the PTCD sufficiently. 30 of these cases who had PTCS showed suspect hepatic and pancreatic malignancies. In contrast to the brush cytology (14% false negative) the biopsies revealed insufficient histology in 33%. However, in 3 cases a more extended tumor site was seen that at the initial exploration, shown by ERCP.
在44例胆道梗阻患者中，在经皮经肝胆道引流术（PTCD）期间进行了经皮经肝胆道镜检查（PTCS）。所有患者的梗阻均可通过PTCD充分减压。其中30例行PTCS的病例显示怀疑有肝脏和胰腺恶性肿瘤。与刷检细胞学检查（假阴性率为14%）相比，活检显示33%的病例组织学检查不充分。然而，有3例患者发现肿瘤部位比最初通过内镜逆行胰胆管造影（ERCP）探查时所见的范围更广。
