Abstrakt:	Introduction: Colorectal liver metastases (CRLM) infiltrating the hilar bifurcation is rarely described. We investigated the outcome of partial hepatectomy combined with resection of the hilar bifurcation. Methods: Data collection for patients who underwent resection for CRLM at our institution was performed prospectively from January 2008 to August 2021. Follow-up ended in August 2023. Patients with and without bile duct infiltration of CRLM were analyzed retrospectively. The primary endpoints were overall (OS) and recurrence-free survival (RFS). Results: A total of 1,156 liver resections were screened. Out of those, 18 were combined resections of the liver and the hilar bifurcation. Bile duct infiltration of CRLM was histologically proven in 5 of 18 cases. Preoperative mild obstructive jaundice occurred in 6 of 18 patients and was treated by drainage. Out of those, only 2 had a confirmed infiltration of the hilar bifurcation by CRLM. The median recurrence-free survival (RFS) was 10 months in those patients with bile duct infiltration compared to 9 months in those with no infiltration ( p = 0.503). Conclusion: While CRLM is common, infiltration into the central biliary tract is rare. Tumor invasion of the biliary tree can cause jaundice, but jaundice does not necessarily mean tumor invasion. We have shown that combined resection of the liver and hilar bifurcation for CRLM is safe and infiltration of the bile duct by CRLM did not seem to have a significant effect on RFS or OS.
