Hepatic resection in patients with cirrhosis and hepatocellular carcinoma.
Hepatic resection can be performed safely in carefully selected patients with cirrhosis. To minimize morbidity and mortality, it is essential to reliably estimate functional hepatic reserve and the extent of tumor before resection is performed. Child's classification is a reliable predictor of long term survival, but a more sensitive measure of hepatic function is needed to predict early morbidity and mortality. Child's classification can also be used to stratify patients and exclude those at high risk from hepatic resection. Promising predictors of operative mortality focus on the mitochondrial function of hepatocytes and include cytochrome a (+a3) contents and the redox tolerance index. Patients with advanced cirrhosis are not candidates for extensive hepatic resection and require careful evaluation before consideration for any hepatic resection. In patients with well-compensated cirrhosis and unifocal tumors, the procedure of choice is an anatomic resection of the tumor. If tumor size and location allows, a segmentectomy offers the best outcome, minimizing postoperative liver dysfunction while offering a long term outcome not dissimilar to a major liver resection. In highly selected patients with incidental tumors, a central tumor and perhaps in patients with multifocal hepatocellular carcinoma, hepatic transplantation may be of benefit. By using the appropriate predictors of hepatic function, refined surgical techniques and optimal postoperative care, a mortality rate of less than 10 per cent is achievable in cirrhotic patients with hepatocellular carcinoma who require resection.
