Background This study aimed to evaluate the usefulness of perioperative indocyanine green elimination rate (ICG‐K) as a predictive factor of posthepatectomy liver failure (PHLF). Methods This study enrolled 193 patients who underwent hepatectomy between 2013 and 2019. We analyzed the relationship between estimated ICG‐K (ICG‐Krem) calculated by the preoperative ICG‐K and the residual liver volume ratio, ICG‐K at days 1 and 7 after hepatectomy (ICG‐Kpod1, ICG‐Kpod7), and grade B or C PHLF. Results Grade B and C PHLF were observed in eight and two patients, respectively. ICG‐Krem and ICG‐Kpod1 were highly correlated (correlation coefficient [CC] 0.715), and ICG‐Krem and ICG‐Kpod7 were moderately correlated (CC 0.653). Receiver‐operating characteristic curve analyses indicated that ICG‐Krem and ICG‐Kpod1 had moderate diagnostic value, while ICG‐Kpod7 had high diagnostic value (area under the curve 0.703, 0.845 and 0.937, respectively). Multivariate analysis demonstrated that ICG‐Kpod7 (relative risk [RR] 26.04, P = .012) and postoperative bile leakage (PBL) (RR 226.0, P < .001) were independent predictive factors for PHLF. PBL induced PHLF in seven patients, respectively. Conclusions ICG‐Krem correlated well with postoperative ICG‐K, having moderate accuracy as a predictor of PHLF. However, the clinical relevance of postoperatively measuring ICG‐K is limited because PHLF is greatly affected by surgical and postoperative factors.
