Abstract    Objective    To investigate surgical indication for primary liver cancer according to analyze operative and perioperative factors of regular hepatectomy and irregular hepatectomy. Methods    The operative and perioperative factors of 274 cases of regular hepatectomies and 586 cases of irregular hepatectomies in primary liver cancer performed from 1990 to 2010 at Chinese PLA Air Force General Hospital were investigated retrospectively according to their medical documentation. Results    Statistical analysis showed that the regular hepatectomy need a more stringent requirements in the liver function and more liver volume, blood loss, transfusion, moe operation time than the irregular hepatectomy. It also increased the rate of postoperative complications. But the tumor volume of regular hepatectomies was significantly greater than the irregular hepatectomies, and the proportion of three sections hepatectomy or more sections is significantly higher than the irregular hepatectomies. Conclusion    For tumors less than 5cm of liver cancer, irregular hepatectomy can retain more functional liver parenchyma. Maybe it is more conducive to the recovery of patients after the operation and reduce the associated complications.
