Brief Summary: This is a multicentric, retrospective, real-world study to investigate the surgical outcomes of minimally invasive surgery compared with open surgery for Perihilar Cholangiocarcinoma (PHC), with the perioperative characteristics and long-term overall survival being compared. We aimed to find out whether the minimally invasive surgery is safe or feasible for PHC. And we also want to find out patients with what kind of characteristic can be benefit from the minimally invasive surgery compared with the open approach.

| postoperative complications | Postoperative complications were reviewed within 90 days after surgery and graded according to Clavien-Dindo (CD) classification system.Postoperative biliary leakage, hemorrhage, and liver failure were defined and classified according to the criteria set out by the International Study Group of Liver Surgery (ISGLS). Wound infection was defined as purulent drainage from the incision or/and positive findings of culture of the fluid or tissue aseptically obtained from the incision. |
