title: [Risk factors of unplanned reoperation after colorectal cancer surgery: a case-control study].
abstract: OBJECTIVE
  To explore the risk factors of unplanned reoperation after radical resection for colorectal cancer.
  
  
  METHODS
  A retrospective analysis of 60 patients (within 14 to 24 days after the initial surgery) receiving unplanned reoperation after colorectal cancer surgery in the First Affiliated Hospital of Xinjiang Medical University from January 2010 to January 2014 was carried out, comparing with 120 randomly paired patients without reoperation during the same period. Univariate and multivariate Logistic regression analysis was performed to investigate the clinicopathologic characteristics of patients in both groups.
  
  
  RESULTS
  Univariate logistic regression analysis showed that male, massive blood loss, diabetes, high BMI, hypertension and poorer tumor staging were selected as possible risk factors, and surgeon and laparoscopic surgery as conservative factors (all P<0.05). Multivariate logistic regression analysis revealed that massive blood loss (OR=12.935, 95% CI: 2.267 to 73.806, P=0.004), diabetes (OR=1.747, 95% CI: 1.098 to 2.777, P=0.018) and male (OR=1.805, 95% CI: 1.074 to 3.034, P=0.026) were the independent risk factors of unplanned reoperation after radical resection for colorectal cancer.
  
  
  CONCLUSIONS
  For heavy bleeding, diabetes and male gender in patients with colorectal cancer, surgeon should pay attention to prevent the risk of postoperative unplanned reoperation.
