Major hepatic resection: an update.

In 1981, we reported a series of 75 major hepatic resections done over a ten-year period; 58 were for hepatic trauma, nine were for benign disease, and eight were for malignant disease. Since that report, the indications for major hepatic resection have changed, with a more conservative approach to hepatic trauma and a more aggressive approach toward hepatic tumors. In this update, we report 88 hepatic resections from Vanderbilt University Hospital and Metropolitan Nashville General Hospital; 32 were for trauma, 25 were for benign disorders, and 31 were for malignant disease. Since 1977, nine adults and four children have had hepatic resection for primary malignant tumors; there were six hepatocellular lesions, three hepatoblastomas, two malignant hemangioendotheliomas, one malignant hepatoma, and one intrahepatic cholangiocarcinoma. At the time of this writing, the four children have survived for 7.3, 6, 6, and 3.8 years (mean 5.7), and all are alive without evidence of recurrence. For the nine adults, survival has averaged 1.7 years, excluding one postoperative death. Three adult patients are alive at this writing, one of whom is a five-year survivor without evidence of disease. Seventeen adults and one child had hepatic resection for metastatic lesions. In the adults, the primary tumor was in the colon in 14 cases and in the small bowel, stomach, and an unknown site in one case each. The one child had a metastatic Wilms' tumor. Survival has averaged two years, with two long-term survivors (nine years). Six patients are alive at this time. Operative mortality for elective resection has decreased from 12% (2/17) in our earlier report to 3% (1/31) in this series, which has encouraged us to assume a more aggressive approach to the resection of malignant primary and metastatic liver tumors.
