Preoperative risk assessment of hepatic resection for malignant disease.

Abstract

Clinical, laboratory, functional, and volumetric data of 340 consecutive patients undergoing hepatic resection for malignant disease between November 1990 and June 1995 were analyzed. The operative mortality was 3.3% (8/244 patients). Among 178 patients with liver metastases and 66 with primary hepatobiliary tumors the hospital mortality was 4.1% (10/244 patients) and morbidity 22.0% (54/244 patients). Survival after hepatectomy was strongly influenced by the extent of resection quantified by the parenchymal hepatic resection rate. The prediction of fatal postoperative complications can be improved for patients with hepatic metastases by calculating the liver resection index (sensitivity 75%, specificity 83%).
