1083 improve outcome prediction of our model. In this context, a plethora of parameters have already been identified that seem to improve preoperative risk assessment of patients undergoing liver resection.(2-5) Indeed, the combination of preoperative liver function assessment might be beneficial to further characterize patients’ risk for adverse postoperative outcome. However, the central aim of the presented study was to define a preoperative parameter that is easily assessable and highly standardized to provide a reliable and internationally available tool. Future research will have to determine whether additional preoperative assessments will further improve risk stratification in patients undergoing liver resection.
