[Relevant factor analysis on postoperative ileus following radical resection for colorectal cancer].

To investigate the associated factors for postoperative ileus following radical resection for colorectal cancer.Clinical data of 1366 colorectal cancer patients undergoing radical resection by the same surgical team in our hospital from January 2000 to September 2011 were analyzed retrospectively. Univariate analysis and multivariate logistic regression analysis were used to identify the associated factors of postoperative ileus.A total of 70 patients(5.1%) developed postoperative ileus. Univariate and multivariate analyses showed that N2(OR=1.893, 95%CI:1.083-3.306), history of colorectal cancer resection(OR=4.899, 95%CI:1.490-16.110), preoperative obstruction (OR=2.616, 95%CI:1.297-5.280), right hemicolectomy(OR=2.024, 95%CI:1.052-3.894) and left hemicolectomy(OR=3.030, 95%CI:1.401-6.550) were risk factors for postoperative ileus following radical resection for colorectal cancer, while laparoscopic operation(OR=0.520, 95%CI:0.319-0.849) was protective.Postoperative ileus following radical resection for colorectal cancer is associated with surgical procedures. Laparoscopic colorectal resection can reduce the incidence of postoperative ileus.
