BackgroundIn recent years, the importance of oncologic principles in colorectal cancer (CRC) surgery has been emphasized in many studies. Although emergency surgery is related to high morbidity and mortality rates, their adequacy and prognosis in maintaining oncologic principles are still controversial. This study aims to compare the clinicopathological features of CRC patients who underwent emergency and elective surgical resection and also to evaluate their compatibility with oncologic principles and to evaluate their short/long term results.MethodsOf the patients who underwent surgery for CRC, 564 were included in this study. The patients were divided into two groups according to their surgical conditions as an emergency (Group 1) and elective (Group 2). Demographics, clinicopathological features, prognostic factors and survival rates of the patients were evaluated retrospectively.ResultsThere were 104 (18.4%) patients in group 1 and 460 (81.6%) patients in group 2. 61.2% of the patients were male and the mean age was 64.27. There were statistically significant differences between the groups in age distribution, tumor localization, surgical procedures, T- N classification, AJCC stage, presence of mucinous subtype, lymphovascular and perineural invasion. The mean tumor diameter was 5.23±3.48 cm. There was no difference between the groups concerning the adequacy of lymph node harvest, except in patients who underwent low anterior resection. The mean survival time was 475.212 days, and the median survival time was 376 days. The disease-free and overall survival rates were higher in group 2.ConclusionDespite the appropriate oncologic resection, CRC patients operated under emergency conditions had worse short-term and long-term results than the CRC patients operated under elective conditions. Thus, we believe that the prevalence of colorectal cancer screening programs should be increased to reduce the rate of emergency surgery.
