liver dialysis
Liver dialysis is a detoxification treatment for liver failure and has shown promise for patients with hepatorenal syndrome. It is similar to hemodialysis and based on the same principles. Like a bioartificial liver device, it is a form of artificial extracorporeal liver support.〔http://scholar.google.com/scholar?as_ylo=2015&q=liver+dialysis&hl=en&as_sdt=0,14〕〔http://onlinelibrary.wiley.com/cochranelibrary/search〕
A critical issue of the clinical syndrome in liver failure is the accumulation of toxins not cleared by the failing liver. Based on this hypothesis, the removal of lipophilic, albumin-bound substances such as bilirubin, bile acids, metabolites of aromatic amino acids, medium-chain fatty acids and cytokines should be beneficial to the clinical course of a patient in liver failure. This led to the development of artificial filtration and adsorption devices.
Hemodialysis is used for kidney failure and primarily removes water-soluble toxins. However, it does not remove toxins bound to albumin that accumulate in liver failure.
== Prognosis/survival ==
While the technique is in its infancy, the prognosis of patients with liver failure remains guarded. Liver dialysis, currently, is only considered to be a bridge to transplantation or liver regeneration (in the case of acute liver failure) and, unlike kidney dialysis (for kidney failure), cannot support a patient for an extended period of time (months to years).
