Efficacy of the Predicted Operation Time (POT) Strategy for Synchronous Colorectal Liver Metastasis (SCLM): Feasibility Study for Staged Resection in Patients with a Long POT

Background The optimal surgical strategy for resectable synchronous colorectal liver metastases (SCLM), whether simultaneous or staged resections, still remains obscure. The aim of this study was to assess the efficacy of the predicted operation time (POT) strategy, which recommends staged resections in case of POT ≥6 h, otherwise selecting simultaneous resection.
