The goal of this observational study is to learn about the safety and long-term outcomes of volume-restricted liver resection in patients with perihilar cholangiocarcinoma (pCCA) who have an insufficient future liver remnant (FLR). The main question it aims to answer is: Does volume-restricted liver resection improve surgical safety and long-term survival compared with standard treatment in pCCA patients with insufficient FLR? Participants with insufficient FLR who undergo volume-restricted liver resection or receive non-surgical treatment as part of their routine medical care will be followed for survival, postoperative complications, and other clinical outcomes. Data from patients with sufficient FLR undergoing standard radical resection will also be collected for comparison.
