Description: Metachronous colorectal liver metastasis (CRLM) is a complex clinical situation requiring multidisciplinary management. In this episode from the Hepato-Pancreato-Biliary team at Behind the Knife, we discuss a patient presenting with metachronous CRLM and how management may change with varying clinical scenarios. 


Learning Objectives: In this episode, we review the initial workup and pre-operative considerations in a patient presenting with metachronous CRLM.  We discuss key aspects of resectability of CRLM, including physiologic and hepatic fitness, biology of the disease, and technical considerations.  We review the timing and common regimens of systemic treatment for differing clinical scenarios, as well as when adjuncts to treatment may be useful (e.g., portal venous embolization).  Finally, we highlight important aspects of intraoperative and postoperative management.
