Background: Insufficient volume of the future liver remnant (FLR) is a major cause of unresectability in patients with bilobar colorectal liver metastases (CLM). The objective of this study was to evaluate the safety and efficacy of the novel associating portal embolization and artery ligation (APEAL) technique before extended right hepatectomy during a two-stage procedure for CLM.

Despite acceptable oncological outcomes, patients with a pT0 tumor at the time of RC are still at risk of recurrence and progression and should not be considered to be entirely cured. In this population, stringent follow-up according to current recommendations should be effective.
