Abstract
In emergency colorectal cancer surgery, it is necessary to consider the curability of cancer in addition to its life-saving purpose. In this study, we examined 856 cases of colorectal cancer surgery between 2013 and 2022, and divided them into 39 emergency group and 817 elective group. The emergency group had significantly more Stage IV cases, significantly more Hartmann surgery and colostomy, and significantly less D3 dissection. In-hospital mortality was significantly higher in the emergency group （2.6%）. Postoperative chemotherapy was significantly lower in the emergency group （32.4%）, and postoperative chemotherapy was significantly lower in the emergency group in Stage III. Five-year overall survival and five-year relapse-free survival were significantly worse in the emergency group, and by Stage, the emergency group was significantly worse in Stage III. Peritoneal dissemination was the most common type of recurrence. Although the short-term prognosis of emergency colorectal cancer surgery was relatively good, appropriate surgical procedure selection and postoperative chemotherapy may be useful to further improve the long-term prognosis, taking the patient's condition into consideration.
