ObjectiveTo explore the risk factors influenced postoperative complications of colon cancer. MethodsIn this study, 114 patients diagnosed definitely as colon cancer were enrolled from January 2009 to April 2010 in this hospital. The patients were divided into the complication group and non-complication group according to the occurrence of postoperative complications during hospital day. Furthermore, clinicopathological features and operative parameters of patients were compared in two groups, and independent factors for postoperative complications were identified by multiple regression analysis. ResultsThere were statistical differences between two groups in operation time (t=2.034, P=0.032), diabetes mellitus (χ2=5.920, P=0.015), differentiation degree of tumor (χ2=7.163, P=0.028), hospital stay (χ2=0.411, P=0.026), and ASA grades (χ2=11.585, P=0.009). The morbidity of patients with operative time  gt;200 min was significant higher than that ≤100 min (χ2=8.884, P=0.003) and 100-200 min (χ2=7.318, P=0.007). The morbidity of patients with ASA Ⅳ grade was higher than that with ASA Ⅰ grade (χ2=13.426, P=0.000). For tumor differentiation, the morbidity of patients with well-differentiated tumor was higher than that with moderately differentiated tumor (χ2=4.950, P=0.026) and poorly differentiated tumor (χ2=7.476, P=0.006). The hospital stay (P=0.009), age (P=0.024), diabetes mellitus (P=0.018), and ASA grade (P=0.001) were the independent factors for postoperative complications by multivariate regression analysis. ConclusionThe physical quality indexes are the mostly common risk factors of postoperative complications for colon cancer, emphasizing on the high-risk factors and making a targeted and individual treatment plan for each patient are of great important to improve the prognosis.
