SHM Converge Scientific Abstract ePoster Gallery-Ischemic Colitis Outcomes and Early Complications: A Multi-Institutional Inpatient Analysis

Pdf Summary

This multicenter retrospective cohort study used the TriNetX Research Network to examine 8,113 adults hospitalized with a new diagnosis of ischemic colitis, excluding patients with other major colitis causes such as radiation, infectious, ulcerative, or Crohn’s-related disease.<br /><br />Ischemic colitis results from reduced blood flow to the colon and can range from mild, self-limited illness to severe complications such as necrosis, sepsis, and organ failure. Although its incidence is relatively low, risk is higher in older adults, men, and people with atherosclerotic disease. It is often difficult to recognize at presentation, with correct identification occurring in only about 9% of patients.<br /><br />The study found a serious early clinical course. One in five patients died within 14 days, with mortality continuing to rise at 30 and 90 days. Emergency department revisits were common, occurring in 4.5% of patients at 30 days and 9.9% at 90 days. Readmissions were also frequent, at 17.3% and 17.5% over the same periods. The median hospital stay was 2 days, with a mean of 4.6 days.<br /><br />The authors concluded that ischemic colitis carries substantial short-term morbidity and mortality, and that early recognition and timely treatment, including antibiotics and surgery when appropriate, are important. They also noted that reliance on coded data and limited clinical detail were important study limitations.
