RESUMO
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.

BACKGROUND: Normal C-reactive protein (CRP) and white cell count (WCC) are often used to exclude a diagnosis of acute appendicitis in the Emergency Department (ED). Retrospective review of 281 adult patients with acute appendicitis was performed to study the incidence of normal CRP and WCC on admission and examine any possible predisposing factors. METHOD: Retrospective analysis of patient clinical records yielded CRP, WCC, operative diagnosis, time of symptom onset, imaging results and history and examination features. Case-control analysis was performed with patients with normal CRP and WCC considered the case group and those with raised CRP or WCC considered controls. Groups were compared using Mann-Whitney U-test and chi-squared analysis. RESULTS: Of 281 consecutive patients with histologically proven appendicitis, 24 (8.54%) had normal CRP and WCC on presentation to ED. There were no significant differences in age, sex or time to blood collection between groups. Three patients had normal WCC and CRP and an Alvarado score of 4 or less on presentation. Three patients had persistently normal CRP and WCC on repeated testing. There was a trend towards earlier presentation in patients with normal CRP and WCC with 75.0% versus 58.4% presenting within 24 h of symptom onset (OR 2.14, P = 0.112). CONCLUSION: Acute appendicitis remains diagnostically challenging and cannot be excluded on the basis of normal CRP and WCC. Serial clinical and biochemical assessment is warranted in patients with acute abdominal pain, particularly in those presenting early after symptom onset.
