ObjectiveTo investigate factors associated with postoperative complications after laparoscopic radical surgery in rectal cancer.MethodsThe clinical data of patients with rectal cancer performed by the laparoscopic radical resection from February 2013 to December 2016 were analyzed retrospectively. All the data were analyzed by the t test, chi-square test or logistic regression analysis.ResultsThere were 343 patients with rectal cancer performed by the laparoscopic radical resection. The postoperative complications occurred in the 97 (28.3%) patients. The result of univariate analysis showed that the postoperative complications rate was associated with the gender, age, body mass index, preoperative anemia, preoperative comorbidity, location and diameter of tumor, operative time, and surgeon experience (all P<0.050). The results of logistic regression analysis revealed that the gender, age, body mass index, preoperative anemia, preoperative comorbidity, location of tumor, operative time, and surgeon experience were the independent risk factors for the postoperative complications (all P<0.050).ConclusionGender, age, body mass index, preoperative anemia, preoperative comorbidity, location of tumor, operative time, and surgeon experience are independent risk factors for postoperative complications in laparoscopic radical rectal surgery for rectal cancer.
