Since April 1977 percutaneous transhepatic cholangioscopy (PTCS) has been carried out in 428 cases comprising 213 cases of malignant disease and 215 benign cases. PTCS is performed through the dilated sinus track of percutaneous transhepatic biliary drainage. When irregularly dilated and tortuous vessels, which we called tumor vessels, are revealed on biliary strictures or polyps, a correct diagnosis of cancer can be made. Benign biliary strictures with or without gallstones, or polypoid lesions without tumor vessels such as granulomas, can be differentiated by cholangioscopic biopsy. The positive rate of cholangioscopic biopsy in 57 cases of bile duct cancer was 96%. PTCS should be used pre-operatively as a definitive diagnostic procedure for biliary tract strictures and polyps.
自1977年4月以来，已对428例患者进行了经皮经肝胆道镜检查（PTCS），其中包括213例恶性疾病患者和215例良性疾病患者。PTCS是通过经皮经肝胆道引流扩张后的窦道进行的。当在胆管狭窄或息肉上发现不规则扩张和迂曲的血管（我们称之为肿瘤血管）时，可做出正确的癌症诊断。通过胆道镜活检可鉴别有无胆结石的良性胆管狭窄或无肿瘤血管的息肉样病变，如肉芽肿。57例胆管癌患者的胆道镜活检阳性率为96%。PTCS应在术前作为胆道狭窄和息肉的确定性诊断方法使用。
