Perioperative Outcomes of Simultaneous Colorectal and Liver Resections

Simultaneous Resection of Colorectal Cancer and Synchronous Liver Metastases: What Determines the Risk of Unfavorable Outcomes? A Retrospective International Multicenter Study

The use of a simultaneous resection in patients with synchronous colorectal liver metastases has increased over the past decades. However, it remains unclear when a simultaneous resection is beneficial and when it should be avoided. The objective of this retrospective study is therefore to compare the outcomes of a simultaneous resection for synchronous colorectal liver metastases in different settings, and to assess which factors are independently associated with unfavorable outcomes.

Inclusion Criteria:

• Elective minimally invasive or open simultaneous resection of colorectal cancer and synchronous colorectal liver metastases

Exclusion Criteria:

• (Partially) robotic-assisted or thoracoscopic procedures
• First stage of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS)
• Patients that underwent major concurrent procedures
