Abstract: Objective To analyse the risk factors of postoperative infection in patients underwent laparoscopic resection of hepatic hemangioma. Methods The clinical data of 286 patients underwent laparoscopic resection of hepatic hemangioma between July 2012 and December 2014 was retrospectively analyzed. The patients were divided into different groups according to different clinical features. The prevalence of postoperative infection was analyzed by univariate analysis,and the independent risk factors were confirmed by Logistic regression analysis. Results The postoperative infection occurred in 77 cases（26.92%） among 286 patients in our series; the percentage of postoperative infection was 21.5% and 34.2%,respectively,in patients younger than and greater than 60-year-old（P<0.05）,and they were 22.1% and 37.9% in patients having their liver resected < 35% and ≥ 35%（P<0.05）,18.6%,29.1% and 39.3% in patients with hemangioma on the left,right and both left and right lobe （P<0.05）,21.9% and 43.3% in patients with lesion size less than 10 cm and with greater than 10 cm （P<0.05）,23.6% and 39.3% in patients without and with history of chronic diseases（P<0.05）,24.4% and 33.3% in patients with normal and with elevated serum ALT levels（P<0.05）,22.1% and 41.1% in patients with bleeding amount <300 ml and in patients with bleeding amount ≥300 ml （P<0.05）,24.4% and 38.5% in patients without and with blood transfusion（P<0.05）,and 22.4% and 55.0% in patients without and with postoperative complications （P<0.05）;Logistic regression analysis revealed that liver resection ratio,lesion size,chronic diseases history,amount of bleeding,blood transfusion and postoperative complications were related to the prevalence of postoperative infection in patients underwent laparoscopic resection of hepatic hemangioma（P<0.05）. Conclusion The postoperative infections might occur in patients underwent laparoscopic resection of hepatic hemangioma,which needs special concern in patients with risk factors.
