The effect of different hepatic vascular exclusion on prognosis of patients undergoing hemihepatectomy

Abstract

Objective To assess the effect of three different liver vascular exclusions on prognosis of patients undergoing hemihepatectomy.Methods Clinical data of 216 patients undergoing hemihepatectomy were analyzed retrospectively.Ninety-eight out of 216 patients received Pringle maneuver during hepatectomy in group A,71 patients of selective liver inflow and outflow vascular exclusions in group B,47 patients using liver hanging maneuver combining with selective liver inflow and outflow vascular exclusions were in group C.Results There was no difference in operation time between the three groups ( t =0.72,0.83,and 0.67,P ＞ 0.05 ).The intraoperative blood loss and transfusion in group B and C were less than that in group A (t =3.72,3.83 and 4.11,4.07,P ＜0.05).Serum albumin level on day 1 and day 3 in group B and C were higher than that in group A (t =3.65,3.77,and 3.90,3.74,P ＜0.05 ).Serum total bilirubin level on day 3 and 5 in group B and C were lower than that in group A ( t =4.13,5.01,and 4.09,3.99,P ＜0.05).Serum alanine aminotransferase on day 1,3 and 5 in group B and C were lower than that in group A ( t =5.36,6.14,and 5.70,7.01,and 4.94,3.98,P ＜ 0.05 ).Postoperative complication rate in group A was higher than that in group B and C ( x2 =13.71 and 23.56,P ＜ 0.05 ).The 3-year survival rate of patients with malignant tumor in the three groups were not significantly different (t =2.38,P ＞ 0.05 ).Conclusions Intraoperative blood loss and transfusion and postoperative complication rate can be reduced,and liver injury can be diminished in hemihepatectomy using selective liver inflow and outflow vascular exclusion alone and or in combination with a liver hanging maneuver.
