Liver resection is a surgical treatment adopted to treat liver cancer or benign liver lesions which need to be removed. During the operation, the liver portion affected by the benign or malign cancer is surgically removed.

Generally, liver resections cannot be performed on patients with advanced cirrhosis, given that the clinical conditions of the liver, and, as a consequence, of the entire organism would not be able to undergo such a trauma. The resected portion of the liver regenerates within few weeks.

Patients susceptible to liver resection therapy are affected by primitive or secondary neoplasms (for instance metastases from other cancers) of the liver limited to one hepatic lobe, with good liver function and no vascular involvement. Also benign lesions, such as adenomas or echinococcus cysts, can be resected if symptomatic.
