One Hundred Consecutive Liver Transplants Using Institutes Georges Lopez-1 Preservation Solution: Outcomes and Prognostic Factors.

Background: There are only 4 prior studies reporting on outcomes of liver transplantation (LT) using Institutes Georges Lopez-1 (IGL-1) preservation solution. Detection of negative predictors of LT using IGL-1 may help finding strategies to protect selected recipients at higher risk of graft failure and death.

Methods: Review of all consecutive adult patients who underwent a first whole-graft LT using IGL-1 at authors' institution from 2013 to 2016.
