Risk factors for infectious morbidity in gallbladder cancer patients treated surgically

Background/Aims: To explore risk factors associated with postoperative infectious morbidity in gallbladder cancer patients. Methodology: We investigated 58 consecutive patients undergoing surgery for primary gallbladder cancer between January 2000 and June 2005 in our hospital. Records of all patients were retrospectively reviewed. Twenty-two independent tumor-, patient-, and treatment-related variables were analyzed. The dependent variable was clinical infectious complications. A binary logistic regression analysis was used to assess the independent association of variables with the dependent variable. Results: Overall surgical morbidity was 33% (19/58), and 14 (24%) of the 58 patients developed infectious complications postoperatively. On univariate analysis, presence of jaundice, hypoalbuminemia and intraoperative blood transfusion were found to be significantly associated with infectious morbidity. The multivariate analysis of logistic regression disclosed that presence of jaundice and intraoperative blood transfusion of 4 units or more only showed marginally significant impacts on infectious complications (odds ratio, 8.004, 7.782; 95% confidence interval, 0.886-72.278, 0.914-66.283, respectively), while weight loss and hypoalbuminemia were significantly associated with infectious complications postoperatively (odds ratio, 9.609, 40.257; 95% confidence interval, 1.269-72.253, 3.901-415.438, respectively). Conclusions: Hypoalbuminemia and weight loss are significantly associated with postoperative infectious morbidity independently. While presence of jaundice and intraoperative blood transfusion of 4 units or more appear to be marginally significant factors, modality of operation or liver resection, blood loss, and additional gastrointestinal operation are not risk factors.
