A comparison of clinicopathologic features of the patients with colorectal cancer cfter emergency and elective surgery

Abstract

The importance of oncologic principles in colorectal cancer has been particularly emphasized in recent years. There are several studies on the quality of the conditions of emergency surgery and comparison of stage, mortality and morbidity rates between patient who underwent emergency and elective surgery. This study aimed to investigate and compare the clinicopathologic characteristics of patients with colorectal cancer according to their surgical conditions whether urgent or elective. Medical records of 564 patients, who underwent colorectal resection between January 2011 and March 2017 anddiagnosed with colon/rectum adenocarcinoma after pathological examination, were investigated retrospectively. There were 104 (18.4%) patients in the emergency surgery group and 460 (81.6%) patients in the elective surgery group. Majority of the patients were male61.2%, and the mean age was 64.27. The patients who had rectal tumor were 19.7% of all cases, and the tumor was located in colonic segments in the remaining 80.3%. Low anterior resection was determined as the most common procedure with the percentage of 23.2%. Anterior resection was the most common procedure in emergency surgery group (27.9%). There was no significant difference between the mean lymph node count in terms of the type of the operation, on the basis of surgical condition. When the factors such as age, gender, tumor location, type of the operation and stage of cancer that have effects on adequate lymph node dissection, were analyzed; the only statistically significant difference was found between emergency and elective cases of the transverse colon tumors (p<0.05). While postoperative complications had no effect on the length of hospital stay, having an ostomy and an advanced cancer found to be prolonging this duration (p<0.05). Surgical conditions have been shown to not affect the lymph node dissection which is an important factor determining the oncological process of the patient.
