Abstract: Objective:To observe and analyze the therapeutic effect of right hemihepatectomy by liverhangingmaneuver anterior approach.Methods:60 patients with primary liver cancer were randomly divided into experimental group(n=30) and control group(n=30) from March 2014 to March 2019.The control group was treated with traditional hepatectomy,and the experimental group was treated with liverhangingmaneuver anterior approach hepatectomy.The surgical indexes,postoperative complications and prognosis of the two groups were observed and compared.Results:Compared with the control group,the experimental group had less intraoperative blood loss,shorter operation time,less tumor rupture and less plasma infusion,and the differences of operation related indexes between the two groups were statistically significant(P<0.05).The incidence of postoperative complications of infection,pleural effusion，bilirubin elevation and 1year mortality in the experimental group were 33.3% and 6.67% respectively,while those in the control group were 73.3% and 20.0%，respectively.There were significant differences in the incidence of postoperative complications and 1year mortality between the two groups(P<0.05).Conclusion:The application of liverhangingmaneuver anterior approach hepatectomy in patients with primary liver cancer can reduce postoperative complications and mortality.

Key words: anterior approach hepatectomy, liver cancer, postoperative complications
