Abstract: Objective To investigate the risk factors of common complications occurrence in patients with malignant and benign hepatic disease after laparoscopic hepatectomy.Methods 131 patients with malignant and benign hepatic disease receiving laparoscopic hepatectomy between January 2011 and December 2014 were recruited in this study. The patients were classified according to gender，age，ASA classification，Child-Pugh class， body mass index （BMI），alpha-fetoprotein（AFP），albumin（ALB），tumor size，blood loss，blood transfusion， abdominal surgery history，laparotomy and surgery time to analyze the risk factors by univariate analysis and by multivariate Logistic analysis.Results Out of 131 patients，30（22.9%） had complications after laparoscopic hepatectomy，including pneumonia in 12 （9.2%），bile leakage in 5（3.8%），ascites in 6（4.6%），pleural effusion in 4（3.1%），gas embolism in 2（1.5%）and shock in 1（0.8%）；The univariate analysis showed that the complications occurrence rate in patients younger than 60 years，ASA classification grade Ⅱ，Child-Pugh class A，lower AFP levels，less bleeding，without laparotomy and shorter operative time were lower than in their opposite partners，and the differences were all significant （P<0.05）；Multivariate Logistic regression analysis showed that age，Child-Pugh class， amount of bleeding，laparotomy and surgical time were independent risk factors for complications occurrence in patients after laparoscopic hepatectomy.Conclusion It must be emphasized that the age，Child-Pugh class，bleeding，laparotomy and surgical time should be taken into consideration to prevent common complications occurrence in patients with hepatic tumors after laparoscopic hepatectomy.
