BACKGROUND Estimation of the functional reserve of the remnant liver is important to reduce morbidity and mortality. AIM To estimate the functional reserve of the remnant liver in patients with hepatocellular carcinoma (HCC). METHODS We reviewed the medical records of 199 patients who underwent resection of HCC. Hepatic clearance of the remnant liver was calculated using fusion images of 99mTc-labelled galactosyl-human serum albumin liver scintigraphy and computed tomography. Posthepatectomy liver failure (PHLF) was classified according to the International Study Group of Liver Surgery. Complications was classified according to Clavien–Dindo classification. We analyzed by the risk factors for PHLF, morbidity and mortality with multivariate analysis. RESULTS Twenty-seven (30%) patients had major complications and 23 (12%) developed PHLF. The incidence of major complications increased with increasing albumin–bilirubin (ALBI) grade. The area under the curve values for hepatic clearance of the remnant liver, liver to heart-plus-liver radioactivity at 15 min (LHL15), and ALBI score predicting PHLF were 0.868, 0.629, and 0.655, respectively. The area under the curve for hepatic clearance of the remnant liver, LHL15, and ALBI score predicting major complications were 0.758, 0.594, and 0.647, respectively. The risk factors for PHLF and major complications were hepatic clearance of the remnant liver and intraoperative bleeding. CONCLUSION The measurement of hepatic clearance may predict PHLF and major complications for patients undergoing resection of HCC.
