Aims: The morbidity rate of hepatic resection for hepatocellular carcinoma (HCC) remains high. To clarify predictors and the prognostic significance of operative complications in patients with HCC, we conducted a comparative retrospective analysis of 291 patients with HCC who underwent hepatic resection. Methods: Operative complications included hyperbilirubinemia, ascites, hemorrhage, respiratory and cardiovascular diseases, bile leakage and abscess formation, renal failure, wound infection, and pleural effusion. Predictors of operative complications and their prognostic Value for long-term survival were studied by univariate and multivariate analyses. Results: Mortality and morbidity rates were 7.2% and 42.6%. The main operative complications were ascites (n = 30), intraabdominal abscess (n = 25), hyperbilirubinemia (n = 19), wound infection (n = 16), pleural effusion (it = 10) and intraabdominal hemorrhage (12 = 9). By a multivariate logistic regression model, Child-Pugh class B and increased operative blood loss (>= 1200 ml) were independent predictors of postoperative complications. Among 243 patients without operative death, the 5-year overall survival rate was significantly lower in patients with operative complications (34.3%) than in those without these complications (48.7%). By the multivariate Cox proportional hazards model, the presence of operative complications was an independent predictor of poor overall survival as well as presence of portal invasion. Conclusions: Child-Pugh class B and operative blood loss >= 1200 ml were independent predictors of complications after hepatic resection for HCC. Long-term survival is poorer in patients with postoperative complications. Decreasing operative blood loss may result in fewer postoperative complications and better long-term survival of HCC patients. (C) 2009 Elsevier Ltd. All rights reserved.
