title: Results of surgery for colorectal carcinoma with obstruction.
abstract: OBJECTIVE
  Emergency surgery for obstructing colorectal carcinoma is thought to be associated with poor survival. The aim of the study is to assess the results of surgery for obstructing colorectal cancer.
  
  
  METHODS
  From 1987 to 2004, 80 patients underwent emergency surgery for completely obstructing colorectal carcinoma (COC), and 171 patients underwent elective surgery for non-obstructing cancer (NOC). Morbidity, mortality, and the late outcome were assessed.
  
  
  RESULTS
  The groups were comparable for age, gender, tumor distribution, histopathologic characteristics, stage, morbidity, concomitant operations, recurrence, and sites of recurrence. High ASA class, poor performance status, and high mortality rate were recorded in COC group (p < 0.05). Mortality was related to ASA class (p < 0.001), performance status (p < 0.001), and obstruction (p = 0.014). ASA class was the single independent factor of morbidity (p < 0.001). The groups were comparable for survival (p > 0.05).
  
  
  CONCLUSIONS
  Obstructing colorectal carcinoma seems to be associated with high mortality rate, but long-term survival seems to be the same with non-obstructing carcinoma.
