Summary
Hilar cholangiocarcinoma is a highly aggressive malignancy, and surgical resection remains the only potentially curative treatment. Due to the frequent involvement of major vascular structures, vascular resection is increasingly performed to achieve negative surgical margins; however, its impact on survival and postoperative outcomes remains controversial. This retrospective study aims to evaluate the association between vascular resection and clinical outcomes, including survival and postoperative outcomes, in patients with hilar cholangiocarcinoma undergoing curative-intent surgery.
