Background and Objectives Preoperatively evaluating reserved liver function is critical in preventing posthepatectomy liver failure (PHLF) in patients undergoing liver resection. The commonly used indocyanine green (ICG) clearance test has several drawbacks. Patients would benefit from a more reliable and straightforward means of assessing the risk of PHLF. Methods This study included 277 patients with hepatocellular carcinoma (HCC) undergoing liver resection. The predictive value of known risk factors for PHLF was compared to that of ICG. Results PHLF was identified in 25 out of 277 patients (9.0%). Multivariate logistic regression analysis for identifying predictors for the PHLF development revealed platelet count and resected liver volume as significant independent predictors. In a subgroup analysis based on resected liver volume, platelet count was significantly correlated with PHLF in both larger volume (≥100 g) and smaller volume resection groups (<100 g), although ICG R15 level was associated with PHLF only in larger volume group. Conclusions Platelet count is superior to ICG R15 level in predicting PHLF development in HCC patients.
