The body mass index and serum glycated hemoglobin levels were significantly higher in the NAFLD group than in the VH group. There were no significant differences in operative time and bleeding amount. Moreover, the morbidity and the length of postoperative hospital stays were similar across both groups. The pathological results showed that the tumor size was significantly larger in the NAFLD group than in the VH group. No significant differences between the groups in overall or recurrence\u2010free survival were found. In a subgroup analysis with matched tumor diameters, patients in the NAFLD group had a better prognosis after hepatectomy than those in the VH group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Surgical outcomes after hepatectomy were comparable between the groups.
