肝门部胆管癌(HC)是指累及胆囊管开口及以上1/3的肝外胆管,并常扩展至肝管汇合部和一侧或双侧肝管的恶性肿瘤,其中58%～75%发生在肝胆管分叉处,又称中央型胆管癌或Klatski肿瘤[1]。HC在肝外胆管癌中发病率较高,达75%左右。由于其发现时已处于中、晚期,故手术切除率低、预后差,因此提高肝门部胆管癌的早期诊断对其
Hilar cholangiocarcinoma (HC) refers to the involvement of the cystic duct more than 1/3 of the extrahepatic bile duct and often extended to the junction of the hepatic duct and one or both of the hepatic duct malignancies, of which 58% to 75% Occurs in the bile duct bifurcation, also known as central cholangiocarcinoma or Klatski tumor [1]. HC in the extrahepatic bile duct cancer in the higher incidence of up to 75%. Because it was found in the late, so the low rate of surgical resection, the prognosis is poor, so to improve the early diagnosis of hilar cholangiocarcinoma on its
