MARS treatment in posthepatectomy liver failure

Posthepatactomy liver failure (PHLF) is a dramatic complication following extensive liver resection or liver resection in a compromised liver, leading to death in 80% of cases. Molecular Adsorbent Recirculating System (MARS) is able to extract water and protein bound toxins out of the blood in liver failure patients. This paper describes the initial experience in the Netherlands using the MARS liver assist device in five patients with PHLF. In all patients, improvement of biochemical parameters was observed during MARS treatments along with clinical improvement in three patients. One patient survived. No clear guidelines for MARS treatment and prognostic factors for outcome after MARS treatment with regard to this patient group are available. In this paper, a MARS treatment regimen for PHLF is suggest based on literature and our experience.
