Extracorporeal therapies for post-liver transplant recipient: The road less traveled.

Abstract

Extracorporeal therapies have a definite role in patients with acute liver failure, acute on-chronic liver failure, and progressive chronic liver disease. They act as a bridge-to-transplant in these patients. With the increasing success of liver transplantation, the immediate postoperative complication spectrum continues to expand. Extracorporeal therapies can play an important role in managing these complications. However, the literature on extracorporeal therapies in the post-liver transplant period is limited. This review article discussed various extracorporeal therapies that are still evolving or marred by limited evidence but can improve patient outcomes. These extracorporeal therapies can be divided into two subgroups: (1) Therapies for infective complications. Endotoxin and cytokine adsorption columns; and (2) Therapies for noninfective complications like small for size syndrome, primary allograft nonfunction, early allograft dysfunction, hyperacute rejection, hepatopulmonary syndrome, etc. (plasma exchange, double plasma molecular adsorption, molecular adsorbent recirculation system, and extracorporeal membrane oxygenation, among others).
