Analysis of risk factors of surgical site infection in patients with colorectal cancer / 中国基层医药

ABSTRACT

Objective To investigate the risk factors of surgical site infection in patients with colorectal cancer.Methods Clinical data of 542 patients with colorectal cancer were retrospectively studied.According to the infection of surgical site or not,all patients were assigned into infection group (n =48) or non-infection group (n =494).The risk factors of surgical site infection were analyzed.Results Compared with non-infection group,the patients in the infection group got significant increase in age [(67.74 ± 9.46) years vs.(57.63 ± 9.94) years,t =7.593,P =0.000],significantly higher rate of diabetes (25.00％ vs.8.70％,x2 =12.843,P =0.000),significantly x higher rate of open surgery (70.83％ vs.33.81％,x2 =25.946,P =0.000),and significantly longer operation duration [(123.45 ± 23.56) min vs.(110.47 ± 19.47) min,t =10.485,P =0.000].Logistic study showed that age,diabetes,open surgery and operation duration were risk factors for the development of surgical site infection (all P ＜ 0.05).Conclusion Age,diabetes,open surgery and operation duration are risk factors for the development of surgical site infection in colorectal cancer.
