Perioperative factors related to prognosis of regular hepatectomy in comparison with irregular hepatectomy

Background The aim of this research was to analyze the perioperative factors of regular hepatectomy and irregular hepatectomy.The superiority of the clinical application of the two methods was compared in the perioperative period.Methods From 1986 to 2011,1798 patients underwent consecutive liver resections with regular hepatectomy and irregular hepatectomy at the Air Force General Hospital of People＇s Liberation Army and the General Hospital of Chinese People＇s Liberation Army.Their medical documentation was investigated retrospectively.Results In patients on whom regular hepatectomy and irregular hepatectomy were performed,there was no significant difference in perioperative blood loss,complications,in-hospital mortality,hospital stay,and so on.But in regular hepatectomy,operating time was an independent risk factor （P ＜0.001,OR=1.004）.Conclusions There was no significant difference between the perioperative risk of regular hepatectomy and that of irregular hepatectomy.
