Aim: Colorectal cancers (CRC) are amongst the most commonly encountered cancers. The symptoms associated with CRCs depend on the tumour localization, stage and the presence of complications during diagnosis. In this study we aimed to reveal the mortality rates and factors affecting mortality of patients who undergone emergency and elective operation due to CRCs. Method: Patients that undergone surgery after being diagnosed with CRC were sorted into two groups: emergency cases (group 1) and elective cases (group 2). Groups were compared in terms of gender, comorbid disease history, liver metastases, presence of anastomotic leaks, tumoural colon segments with tumour, mortality rates, preoperative and postoperative urea, creatinine and haemoglobine values. Results: The mean age of the 308 patients was 62.4±11.9 and the male/female ratio was 1.4. Emergency operation was performed for 53 patients. Two-hundred-sixteen patients had tumours located on the rectosigmoid junction. Seventeen patients had mortality on early postoperative 30 day. Mean age, mortality rate and liver metastases were higher in patients who undergone emergency operation (p=0.037, p=0.007 and p<0.001). The patients who were electively operated and had mortality had higher mean age, liver metastasis rate, preoperative and postoperative urea and creatinine rates than living elective cases (p=0.003; p<0.001; p=0.003; p=0.002 and p=0.044). The patients who undergone emergency operation and had mortality had higher postoperative creatine level and postoperative pulmonary embolism development risk (p=0.040 and p=0.013). Conclusion: The patients who undergone emergency operation because of CRC were observed to have higher mortality rates due to pulmonary embolism development risk with emergency operation conditions and higher levels of creatinine. Mortality amongst electively operated patients was found to be dependent on many factors.
