Abstract: Hilar cholangiocarcinoma (HCCA) is a common malignant tumor of the biliary system.Radical HCCA resection with combined vascular resection and reconstruction can help achieve R0 re section,improve tumor resectability,and enhance patient outcomes.With the increasing popularity of minimally invasive surgical techniques such as laparoscopy and robotic surgery,more and more centers are beginning to experiment with minimally invasive HCCA resection with combined vascular resection and reconstruction.However,due to the complex anatomy of the hilum and the limitations of minimally invasive techniques,completing HCCA revascularization and reconstruction under minimally invasive conditions is particularly challenging.The author has accumulated considerable experience in minimally invasive HCCA vascular resection and reconstruction.This article will discuss the technical challenges of minimally invasive HCCA vascular resection and reconstruction,indication selection,established revascularization techniques,reconstructive skills,and remedial measures after reconstruction failure.

Key words: hilar cholangiocarcinoma, vascular resection and reconstruction, minimally invasive surgery
