Background And Aim:
The incidence of ischemic colitis (IC) in Japan has been increasing due to the westernization of diet and the aging population. The aim of this study was to evaluate the relationship between endoscopic findings and clinical severity in IC.
Methods:
This retrospective analysis included 106 cases diagnosed with IC that were divided into two groups based on endoscopic findings in the acute stage: redness and erosion (RE) versus longitudinal and circumferential ulcers (LCU). The clinical variables were compared between the two groups. In addition, we investigated the risk factors of IC associated with the severity of the endoscopic findings by multivariate logistic regression analysis.
Results:
The percentage of cases presenting abdominal pain was significantly higher in the LCU group than that in the RE group (p=0.002), as were the baseline serum CRP levels (p=0.0001). The periods of hospitalization in LCU group were longer than in the RE group (p=0.0001). Multivariate logistic regression analysis indicated that ischemic heart disease (IHD) and connective tissue disease were the independent explanatory factor associated with the endoscopic severity of IC (p<0.05).
Conclusion:
We showed clearly that the two endoscopic classifications were accurate indicators of severity and could be used to anticipate severity of IC. Furthermore, we confirmed that IHD and connective tissue disease were the exacerbating factor associated with the severity of endoscopic findings in IC.

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...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

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 transmural...
