Effect of intermittent liver ischemia on outcome in patients with hepatocellular carcinoma on liver cirrhosis

The influence on postoperative liver function of intermittent normothermic hepatic ischemia in cirrhotic patients was studied retrospectively. The mean total ischemia time was 88 (range 30-140) minutes in the hemi-hepatic occlusion group, and 68 (range 10-187) minutes in the total occlusion group. There were no operative deaths due to hepatic failure. Postoperative liver function improved within 1 week of the operation. There was no significant difference in the incidence of postoperative complications between the groups. Thus normothermic hepatic ischemia is tolerated for up to 180 minutes in the cirrhotic liver when an intermittent technique (15 minutes clamped and 5 minutes unclamped) is used.
