Results Liver function classification were Child-Pugh A in all patients. Among them, 57 patients（95%）were score 5 and 3 patients（5%）score 6. Average diameter of tumor was 15.2cm （range 5—27cm）. Among them, diameters of 34 patients （56.7%） were not less than 15cm，and those of 12 patients（20%）were not less than 20cm. Left trisectionectomy was performed in 24 patients, and right trisectionectomy was performed in 36 patients.
