Abstract
Backgrounds
A significant number of patients with colorectal cancer will have an emergency presentation requiring surgery. This study aims to evaluate short-term outcomes for patients undergoing emergency colorectal cancer surgery in Australasia.
Methods
All consecutive CRC from the Bi-National Colorectal Cancer Audit Database was interrogated from 2007 to 2016. Short-term outcomes including length of stay, complication rate and mortality rate were compared between the emergency and elective groups. Logistic regression analysis was performed to identify independent predictors for inpatient mortality. A predictive model for inpatient mortality was constructed using these variables, and its accuracy was then validated by the Bootstrap re-sampling method.
Results
Of 15,676 colorectal cancer cases identified, 13.6% were emergency cases. The emergency group had a higher rate of surgical and medical complications (26.7% vs 22.6%, p < 0.001; 22.8 vs 13.8%, p < 0.001, respectively). Higher inpatient mortality rate was also observed in the emergency group (3.4% vs 2.6%, p = 0.023). Independent predictors for inpatient survival included age, American Society Anaesthesiologists score, emergency surgery and tumour stage. In addition, postoperative complications such as anastomotic leak (odds ratio [OR] 3.78, p < 0.001), sepsis (OR 2.85, p < 0.001) and medical complications (OR 13.88, p < 0.001) had a significant impact in survival in the emergency group. Receiver operating characteristics curve for inpatient mortality was 0.913.
Conclusion
Emergency colorectal cancer surgery carries significant morbidity and mortality. Recognition of the increasing rate of postoperative complications may help minimise the detrimental impact of this event on overall outcomes.

The publisher regret that a typographical error was present in the Table 1 of the original version of this article. The value “20,032” should have been “2” in the Variable column under T stage. The correct table is now presented correctly in this article.
