Abstract

Introduction: Different factors have been associated with increased risk of complications in laparoscopic colorectal surgery. The aim of this study is to identify these factors in our series. Method: Retrospective cohort. All patients undergoing laparoscopic colorectal surgery between January 2000 and June 2012 were included. Patients who had postoperative complications until 30 days postoperatively were identified and analyzed by univariate and multivariate logistic regression. A p value less than 0.2 was used was used as a criteria for entry into the multivariate model. Results: The series consists of 848 patients with a median age of 58 22 years. Main surgical indications were: neoplasia (42.3%), diverticular disease (27.8%) and inflammatory bowel disease (8.8%). Most frecuently-performed procedures were: sigmoidectomy (39.5%), anterior resection of the rectum (13.4%), right hemicolectomy (13%) and total colectomy (8.7%). On univariate analysis, factors associated with complications were age over 75 years (OR 1.82, 95% CI 1.02 to 3.25) and red blood cell transfusion (OR 8.47, 95% CI 3.69 to 19.43). On multivariate analysis, red blood cell transfusion (OR 7.9 95% CI 1.78 to 35.88) and ASA III or IV (OR 3.26 95% CI 1.01 to 17.23) were independent factors associated with postoperative complications. Conclusion: Intraoperative red blood cell transfusion and ASA score III or IV are independent risk factors associated with complications in laparoscopic colorectal surgery.
