The main aim of the study is to determine the predictive value of (99m)Tc-mebrofenin hepatobiliary scintigraphy in assessing the postoperative risk of liver failure within 3 months of extended hepatectomy of 4 or more segments in noncirrhotic liver. The main endpoint is the three-months postoperative liver failure, defined as an increased International Normalized Ratio (INR) and concomitant hyperbilirubinemia (according to the normal limits of the local laboratory) on or after postoperative day 5 according to the international classification of the ISGLS (International Study Group of Liver Surgery) and classified according to its severity in grade A (no change of the patient's clinical management), grade B (deviation from the regular course but without invasive therapy) and grade C (invasive treatment)
