A preoperative prognostic model to predict surgical success in patients with perihilar cholangiocarcinoma

摘要

BackgroundPatients with resectableperihilar cholangiocarcinoma (PHC) on imaging have a substantial risk of metastatic or locally advanced disease, incomplete (R1) resection, and 90-day mortality. Our aim was to develop a preoperative prognostic model to predict surgical success, defined as a complete (R0) resection without 90-day mortality, in patients with resectable PHC on imaging.
