Analysis of postoperative complications and their related factors after laparoscopic-assisted radical surgery in rectal cancer / 肿瘤研究与临床

ABSTRACT

Objective To investigate the factors associated with postoperative complications after laparoscopic-assisted radical surgery in rectal cancer.Methods The clinical data of 310 patients with rectal cancer performed by laparoscopic-assisted radical resection from November 2010 to August 2013 were analyzed retrospectively.The differences between patients with and without postoperative complications were compared.All the data were analyzed by the t test,chi-square test or Logistic regression analysis.Results Among the 310 patients,postoperative complication occurred in 80 patients.On univariate analysis,postoperative complication was associate with gender,age,body mass index,preoperative comorbidity,diameter and location of tumor,TNM staging,operative time and surgeon experience (all P ＜ 0.05).Logistic regression analysis revealed that gender,body mass index,preoperative comorbidity,location of tumor,TNM staging and surgeon experience were independent risk factors for postoperative complications (all P ＜ 0.05).Follow-up was available in 260 patients,with a median follow-up of 18 months (3-30 months).Differences in survival rates between patients with and without postoperative complications were no statistical significance (x2 =1.201,P =0.273).Conclusions Gender,body mass index,preoperative comorbidity,location of tumor,TNM staging and surgeon experience are independent risk factors for postoperative complications in laparoscopic-assisted radical surgery for rectal cancer.The short and medium-term survival time between patients with and without postoperative complications are similar.
