Colitis caused by vasculitis is a rare and poorly understood pathology. Little evidence exists on its clinical presentation, path to diagnosis, and surgical management. In this report, we present a case report and literature review. A healthy 20-year-old male patient presented with hemorrhagic colitis requiring total colectomy with end ileostomy. Pathological examination showed pancolitis with multiple ulcers, transmural inflammation, hemorrhage, and microvascular thrombosis. Extensive serological testing revealed elevated cytoplasmic antineutrophil cytoplasmic antibody (c-ANCA) and eosinophilia, leading to a diagnosis of eosinophilic granulomatosis with polyangiitis (EGPA) and vasculitis-induced colitis. A literature review was subsequently conducted. Nineteen studies were found documenting vasculitis-induced colitis in the absence of inflammatory bowel disease (IBD). Systemic signs of vasculitis, hemorrhagic colitis, and progression to fulminant colitis were present. Of all patients, 40.0% required colorectal surgery and 62.5% of those patients received a stoma; 25% underwent emergency surgery following failed immunosuppression. All cases relied on clinical correlation with serology and/or histopathology to reach a final diagnosis. We report a case of vasculitis-induced colitis caused by c-ANCA−positive EGPA. The review shows that vasculitis-induced colitis without IBD is an important differential that clinicians should be aware of in patients presenting with colitis.

Purpose: A small proportion of colorectal cancer (CRC) surgical patients will require an admission to an intensive care unit (ICU) within the early postoperative period. This study aimed to compare the characteristics and outcomes of patients admitted to an ICU following CRC surgery per hospital type (metropolitan vs. rural) over a decade in Australia. Methods: A retrospective cohort analysis was undertaken of all adult patients admitted to a participating Australian ICUs following CRC surgery between January 2011 and December 2021. The primary outcome was in-hospital mortality. Results: Over the 10-year period, 19,611 patients were treated in 122 metropolitan ICUs and 4,108 patients were treated in 42 rural ICUs. Rural ICUs had a lower proportion of annual admissions following CRC surgery (20 vs. 36, P<0.001). Patients admitted to a rural ICU were more likely to have undergone emergency CRC surgery compared to those admitted to a metropolitan cohort (28.5% vs. 13.8%, P<0.001). There was no difference in in-hospital mortality between metropolitan and rural hospitals (odds ratio [OR], 1.03; 95% confidence interval [CI], 0.73–1.35; P=0.500). There was a general trend for lower mortality in later years of the study with the odds of death in the final year of the study (2021) almost half that of the first study year (OR, 0.52; 95% CI, 0.34–0.80; P=0.003). Conclusion There was no difference between in-hospital mortality outcomes for CRC surgical patients requiring ICU admission between metropolitan and rural hospitals. These findings may contribute to discussions regarding rural scope of colorectal practice within Australia and globally.
