Hepatic resections for primary liver cancer.

Abstract

The medical records of 399 patients who underwent hepatic resection between January 1981 and December 1990 were reviewed. Information regarding the results of the hepatic resection in terms of the operative indication, operative procedure, operative morbidity, and mortality was abstracted. As of the end of 1990, a total of 402 hepatic resections had been completed, including those of 319 primary malignancies, 4 secondary malignancies, 2 gallbladder carcinomas, 42 cases of intrahepatic cholelithiasis, and 35 benign masses. Major hepatic resections were performed on 117 patients (29%), of whom 60 (51%) had histologically proven liver cirrhosis. Minor hepatic resections were performed on the remaining 285 patients (71%). Sepsis was the most frequent complication, which manifested primarily as wound infection (71 cases) or intra-abdominal infection (25 cases). Nonfatal hepatic failure occurred in nine patients with cirrhosis and one patient without cirrhosis. There were 38 operative deaths among the 402 hepatic resections, for an overall operative mortality of 9.4%; 25 of those deaths were due to hepatic failure after the operation, accounting for 66% of the total operative mortality. There was an increasing frequency of hepatic resection during the last 5 years. The indication for resection due to hepatocellular carcinoma increased from 87 to 195 cases. The cumulative data show a decrease in the incidence of complications and the operative mortality rate. In the most recent period, nonlethal postoperative complications occurred in 135 of 286 patients (47%). The overall 1-, 3-, and 5-year survival rates for 172 patients, excluding cases of operative mortality, palliative resection, and re-resection, were 71.0%, 39.8%, and 28.3%, respectively.
