Molecular adsorbent recirculating system treatment for patients with liver failure: The Hong Kong experience

Background: The molecular adsorbent recirculating system (MARS) is an extracorporeal liver dialysis system that allows selective removal of bilirubin and other albumin-bound toxins. We reported here our experience with the use of this technique for management of liver failure at Queen Mary Hospital, Hong Kong. Methods: From December 2002 to 2004, a total of 74 MARS sessions were performed on 22 patients. The cause of liver failure included acute liver failure (n = 2), acute on chronic liver failure (n = 12), posthepatectomy liver failure (n = 4), and posttransplantation allograft failure (n = 4). Results: MARS treatment showed significant reduction in total bilirubin level, serum ammonia level and blood urea, and nitrogen (P
