title: [Factors associated with complications in patients undergoing surgery for obstructing colorectal cancer].
abstract: OBJECTIVE
  To evaluate risk factors associated with morbidity and mortality in patients undergoing surgery for obstructing colorectal cancer.
  
  
  METHODS
  One hundred and eleven patients who underwent emergency surgery for obstructing colorectal cancer from January 2001 to December 2009 were retrospectively reviewed.
  
  
  RESULTS
  Forty-nine patients had obstruction proximal to the splenic flexure and 62 patients at or distal to the splenic flexure. The morbidity and mortality rates of the emergency surgery for malignant obstruction were 21.6% and 5.4%, respectively. Twenty-three patients received resection with primary anastomosis with intraoperative lavage for left-sided lesions. There was no difference in morbidity between right-sided cancer and left-sided cancer(P>0.05). Univariable analysis showed that complications rate was higher in patients with higher ASA score (3-4) and in those aged over 60 years. Multivariate logistic regression analysis revealed that ASA score(3-4) was an independent risk factor.
  
  
  CONCLUSIONS
  Emergency surgery for obstructing colorectal cancer is associated with high rates of morbidity and mortality. Selection of the proper operation and intensive treatment after surgery are recommended in high risk patients.
