肝门部胆管癌

Hilar cholangiocarcinoma

肝门部胆管癌是指位于胆囊管开口以上的肝总管，左、右肝管汇合部和左、右肝管的胆管黏膜上皮癌。由于肝门部特殊的解剖学位置及肝门部胆管癌生物学特性，其极易早期侵犯肝门区血管、神经、淋巴结组织及邻近肝组织，因此，手术难度大，患者预后差。在现代影像学指导下的扩大肝切除术可能给这个凶险的疾病予以希望。但国内外学者就扩大肝切除术存在诸多争议，目前尚无统一的标准。因此，肝门部胆管癌外科治疗亟待规范化，以提高其根治性切除率，减少手术相关并发症发生率和病死率。

Hilar cholangiocarcinoma （HCCA） occurs at the confluence of the right and left hepatic bile ducts. Because of the unique anatomical position and the biological behaviour of HCCA, hepatic vessels, nerves, lymph nodes and adjacent tissues are easily invaded by HCCA. The operation for HCCA is difficult, and the prognosis of patients is poor. Extend- ed hepatectomy guided by imaging techniques shed light on the management of HCCA, while controversies on extended hepatec- tomy exist at home and abroad, and a standard treatment is nee- ded to be formulated. Therefore, the surgical management for HCCA should be standardized for improving the radical resection rate, reducin~ the incidence of complications and mortality.
