This study aims to determine the factors that affect morbidity and mortality in colon and rectum injuries related with trauma, the use of trauma scoring systems in predicting mortality and morbidity. Besides patient demographic characteristics, the mechanism of injury, the time between injury and surgery, accompanying body injuries, admittance Glasgow coma scale (GCS), findings at surgery and treatment methods were also recorded. With the obtained data, the abbreviated injury scale (AIS), injury severity score (ISS), revised trauma score (RTS) and trauma-ISS (TRISS) scores of each patient were calculated by using the 2008 revised AIS. Of the patients, 172 (88.7 %) were male, 22 (11.3 %) were female and the mean age was 29.15 ± 12.392 (15-89) years. The morbidity of our patients were 32 % and mortality were 12.4 %. ISS (p < 0.001), RTS (p < 0.001), and the TRISS (p < 0.001) on mortality were found to be significant. TRISS (p = 0.008), the ISS (p < 0.001), the RTS (p = 0.03), the trauma surgery interval (TSI, p < 0.001) were observed to have significant effects on morbidity. Regression analysis showed that the ISS (OR 1.1; CI 95 % 1.01-1.2; p = 0.02), the RTS (OR 0.37; CI 95 % 0.21-0.67; p = 0.001) had significant effects on mortality. While the effects of TSI (OR 5.3; CI 95 % 1.5-18.8; p = 0.01) on morbidity were found to be significant. Predicting mortality by using scoring systems and close postoperative follow up of patients in the risk group may ensure decreases in the rates of morbidity and mortality.
