The liver can regenerate itself if part of it is damaged or cut away in surgery (Michalopoulos, 2007).
I have been looking at liver damage caused by excess alcohol consumption and according to the NHS,
There's no cure for cirrhosis at the moment.
and
If your liver is severely damaged, a liver transplant may be the only treatment option.
Can you not cut away the damaged area and allow the liver to regenerate or is this kind of damage extensive to the point that the whole liver is damaged?
If the damage is extensive, could you not cut a portion away for regeneration and after regeneration is complete, revisit for another portion to be cut away for regeneration?
