title: Continuous normothermic hemihepatic vascular inflow occlusion over 60 min for hepatectomy in patients with cirrhosis caused by hepatitis B virus.
abstract: OBJECTIVE
  To evaluate the safety of remnant liver in cirrhotic patients who had undergone irregular hepatectomy with continuous normothermic hemihepatic vascular inflow occlusion for over 60 min.
  
  
  METHODS
  A group of 133 cirrhotic patients who had hepatitis B virus accompanied by hepatocellular carcinoma and had undergone irregular hepatectomy by hemihepatic vascular inflow occlusion was studied. According to the time of hemihepatic vascular inflow occlusion, patients were assigned either to the control group, treatment(60) group, or treatment(90) group. The quantity of blood loss and blood transfusion, routine liver biochemistry and postoperative complications were retrospectively analyzed.
  
  
  RESULTS
  The data showed that there were no significant differences in postoperative complications between the three groups. Compared to the preoperative day, the levels of aspartate transaminase (AST), alanine transaminase (ALT), prothrombin time (PT) and serum bilirubin on postoperative days 1 and 3 were significantly increased in all three groups and the levels of albumin and platelet were significantly decreased on postoperative day 1. Duration of hospital stay and the levels of ALT and AST on postoperative days 1, 3 and 7 were higher in the treatment(90) group than in the control group and treatment(60) group (P < 0.05). However, no significant differences were displayed in the length of hospital stay and the levels of AST, ALT, PT, albumin, platelet count and serum bilirubin on postoperative days 1, 3 and 7 between the control group and the treatment(60) group (P > 0.05).
  
  
  CONCLUSIONS
  Hemihepatic vascular inflow occlusion over 60 min is a possible method for irregular hepatectomy in patients with cirrhosis caused by the hepatitis B virus. However, caution must be exercised in utilizing this method where the time of vascular occlusion is over 90 min.
