肝门部胆管癌影像学诊断研究现状

Imaging diagnosis of hilar cholangiocarcinoma

目的肝门部胆管癌(HCCA)是胆道系统肿瘤中常见的恶性肿瘤之一。随着临床认识、检验和影像学检查技术的提高,HCCA诊断报道病例数在增加。由于早期缺乏特异性表现,一经发现多数为晚期患者,导致根治性切除率低,预后差。因此,对具有高危因素的患者,早期筛查和诊断非常重要。目前,影像学检查成为诊断和鉴别诊断HCCA的重要手段。本文重点讨论影像学早期筛查和诊断HCCA的有关进展。

Objective Hilar cholangiocarcinoma(HCCA)is one of the common malignant tumors in biliary system.The reported cases of HCCA increases gradually as the intensive application of imaging examination.Due to the lack of specific manifestations in the early stage of the tumor,most patients are found to be with advanced disease,resulting in a low radical resection and poor prognosis.Therefore,early screening and diagnosis is the top priority for individuals with high risk factors.At present,the imaging detection has become an important means of diagnosis and differentiation of HCCA.In this article,we review the early imaging screening and diagnosis of HCCA.
