Abstract    Central biliary dilatation (BD) is a primary biliary disease characterized by intrahepatic central biliary dilatation with or without extrahepatic biliary dilatation, including B1, B2, D1 and D2 in Dong clinical classification. Because of its great anatomical variability, impaired liver function, difficulty in preoperative evaluation and complicated operation, central BD has a high incidence of complications and poor prognosis. In view of the difficulties in diagnosis and treatment of central BD, comprehensive application of perihilar surgical technique, through preoperative systemic perihepatic portal imaging evaluation and liver function maintenance, individualized surgical treatment and comprehensive postoperative management will help to improve the surgical efficacy of central BD.

Key words: biliary dilatation, perihilar surgical technique

摘要：

中央型胆管扩张症（BD）是以肝内中央胆管扩张为特点，伴有或不伴有肝外胆管扩张的原发性胆管病变，包括了Dong临床分型中的B1、B2、D1和D2型。因其具有解剖变异性大、肝脏功能受损、术前评估困难、手术操作复杂等特点，导致中央型BD的术后并发症发生率高、预后欠佳。针对中央型BD的诊治难点，综合应用围肝门外科技术，通过术前系统的围肝门影像学评估和肝功能维护，实施个体化的手术治疗和全面的术后管理，有助于提高中央型BD的手术疗效。
