OBJECTIVETo analyze operative and perioperative factors associated with hepatectomy.

METHODS2008 consecutive patients undergoing hepatectomy from January 1986 to December 2005 at Chinese People's Liberation Army General Hospital were investigated retrospectively according to their medical documentation. Diagnoses were made on basis of pathological results.

RESULTSMalignant and benign liver diseases accounted for 58.5% and 41.2%, respectively. In the former, primary liver cancer accounted for 76.1% and hilar cholangiocarcinoma for 6.7%. Hemangioma (41.7%) and hepatolithiasis (29.6%) were listed in the first two in the latter group with relatively more patient ratios. Isolated caudate lobe resection was performed in 25 patients and micro-wave inline coagulation was induced in 236 cases of liver resection. In all cases, those with blood loss less than 200 ml accounted for 50.5% (1015/2008), whereas those with more than 400 ml accounted for 28.4% (570/2008). In patients performed micro-wave inline coagulation liver resection, those with blood loss less than 200 ml and more than 400 ml accounted for 60.6% (143/236) and 19.9% (47/236), respectively, which differed significantly from the average level (P < 0.05). The postoperative complication incidence was 14.44% for all cases, 12.54% for primary liver cancer, 16.40% for secondary liver cancer, and 16.32% for hepatolithiasis. Complication incidence of primary liver cancer with tumor size smaller than 5 cm was 11.65% and that with tumor larger than 10 cm was 14.69%. There was no significant difference between the two groups. All-case hospital mortality was 0.55% and that for liver malignant disease was 0.60%, hilar cholangiocarcinoma 2.53%.

CONCLUSIONHepatectomy can be performed safely with low mortality and low complication incidence, provided that it is carried out with optimized perioperative management and innovative surgical technique.
