Purpose: To evaluate factors that influence morbidity and mortality in colorectal injuries. Methods: We reviewed the medical records of 59 patients who underwent emergency operation in JNUH from Jan. 1988 through Dec. 1997. Univariate and<br>multivariate<br>analyses were used to calculate the prognostic significance of the following variables: sex, age, time to operation, preoperative shock, penetrating abdominal trauma index (PATI), APACHE II score, site of injury, organ injury scale (OIS), Flint<br>grade,<br>associated intraabdominal injuries, the sum of transfusion during 48hours of preoperative and postoperative period and operative method.<br>Results: Univariate analysis showed that colorectal organ iujury scale, and operative method were related to the complication, and preoperative shock, APACHE II score, PATI, and transfusion in 48hrs of injury were related to the mortality of<br>colorectal<br>injury. Multivariate logistic regression analysis showed that colorectal organ injury scale (2 vs 1) was significant risk factor in the development of complication, and the odds ratios were 5.0 and 1.69 respectively. The sum of transfusion in<br>48hours of<br>injury was a only significant risk factor in the mortality and the odds ratio was 1.5. Conclusions: We concluded that preoperative condition was very important and preservation of hemodynamic stability was critical in improvement of prognosis. We<br>also<br>concluded that the shortening of operative time and proper management of associated injury may reduce the development of complication and even death.<br>
