AbstractMetabolic dysfunction-associated fatty liver disease (MAFLD) is a term that was proposed in 2020 by a group of international experts. However, the impact of MAFLD on complications after hepatectomy in patients with hepatocellular carcinoma is not clear. The aim of this study is to explore the influence of MAFLD on the complications after hepatectomy in patients with hepatitis B virus-related hepatocellular carcinoma (HBV-HCC). Patients with HBV-HCC who underwent hepatectomy between January 2019 and December 2021 were consecutively enrolled. The predictors of complications after hepatectomy in HBV-HCC patients were retrospectively analyzed. Among the 514 eligible HBV-HCC patients, 117 (22.8%) were diagnosed with concurrent MAFLD. Post hepatectomy complications occurred in 101 patients (19.6%), including 75 patients (14.6%) with infectious complications and 40 patients (7.8%) with major complications. Univariate analysis showed that MAFLD was not the risk factor for complications after hepatectomy in patients with HBV-HCC (P > .05). However, univariate and multivariate analysis revealed that lean-MAFLD was an independent risk factor for post hepatectomy complications in patients with HBV-HCC (odds ratio 2.245; 95% confidence interval 1.243-5.362, P = .028). Similar results were found in the analysis of predictors for infectious and major complications after hepatectomy in patients with HBV-HCC. MAFLD commonly coexists with HBV-HCC and is not directly associated with complications after hepatectomy, but lean-MAFLD is an independent risk factor for post hepatectomy complications in patients with HBV-HCC.Copyright © 2023 the Author(s).
