Background/Aims:
Ischemic colitis (IC), the most common ischemic syndrome affecting the gastrointestinal tract, results from a decreased blood supply to the colon. Persistent symptoms can lead to complications, necessitating surgery. This study assessed the clinical characteristics and risk factors for poor outcomes in IC.
Methods:
This retrospective observational study examined the medical records of 141 patients diagnosed pathologically with IC via surgery or colonoscopy at Chonnam National University Hwasun Hospital between April 2004 and August 2023.
Results:
Eighteen (12.8%) and 123 (87.2%) patients were diagnosed by surgical biopsy and biopsy with colonoscopy, respectively. Multivariate analysis identified right-sided colon involvement, fever, and the absence of hematochezia as risk factors for the progression to surgery (odds ratio [OR]=5.924, 95% confidence interval [CI] 1.009-34.767, p=0.049; OR=24.139, 95% CI 5.209-111.851, p<0.001; and OR=0.076, 95% CI 0.013-0.446, p=0.004, respectively). The in-hospital mortality was 5.7% (8/141), and the patients who died exhibited higher rates of shock. The median (interquartile range) hospital stay was 11 (1-219) days. Patients who had longer hospital stays (≥14 days) had a significantly higher rate of fever but a lower rate of hematochezia.
Conclusions:
A multidisciplinary approach is crucial for determining the need for surgery in patients with right-sided colon involvement, fever, or the absence of hematochezia.

01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
