The development of hepatic metastases in patients with rectal cancer represents an unfavourable prognostic element; chances of curing these patients are often limited by the extension of the neoplastic disease.

The rectum, unlike the colon, presents dual venous drainage, which occurs through the mesen-terico-portal system and internal iliac veins, leading to the inferior vena cava. This dual venous drainage can explain the different frequency for hepatic metastases in colonic or rectal cancer; the incidence of hepatic metastases from colonic tumours is 56.8% and 45.9% in rectal tumours [1].
