The liver can regenerate, and the liver has a high regenerative capacity. Surgical treatment of liver lesions, most of which require removal of the liver, is based on the principle that the liver can regenerate. Under normal circumstances, 70% of the liver removed in non-cirrhotic patients, the liver will not produce failure, all will significantly proliferate within a certain period of time and restore normal liver function. Patients with cirrhosis generally try not to remove more than 50% of the liver, otherwise it can cause liver failure and affect the regeneration of the liver, which in turn affects the recovery of liver function. The liver has a strong regenerative capacity and relies on the ability of liver cells to divide and proliferate to achieve normal regeneration requirements. Don’t worry too much about the clinical damage of liver function, and make sure to take the right treatment according to the etiology, which should be decided according to the specific situation of liver regeneration capacity.
