Simultaneous vs. Staged Resection of Colorectal Cancer With Synchronous Liver Metastases

Patients randomized to staged resection will be operated according to the decision made by the tumor board meeting (liver or colorectal cancer first, based on tumor burden and symptoms), but both resections have to be done within a time period of 4-12 weeks.

In cases with simultaneous surgery, the liver resection is performed prior to colon resection in order to keep a low central venous pressure during the first part of the surgical procedure and to avoid congestion of the anastomosis line owing to possible Pringle manoeuvre.
