Summary
Recurrent ischemic colitis (IC) affects 7.7% of patients, with risk factors including smoking, heart disease, prior surgery, and clopidogrel. Early recognition may be challenging due to atypical presentations.
Area of Science:
- Gastroenterology
- Clinical Medicine
- Epidemiology
Background:
- Recurrent ischemic colitis (IC) is uncommon but clinically significant.
- Risk factors for recurrent IC are not well-defined.
- Understanding recurrence predictors is crucial for patient management.
Purpose of the Study:
- To determine the prevalence of recurrent IC.
- To identify clinical predictors associated with IC recurrence.
Main Methods:
- Retrospective single-center cohort study (2011-2021).
- Included patients diagnosed with IC confirmed by imaging or histology.
- Excluded patients under 18, pregnant women, and those with other colitis causes.
Main Results:
- 11% of 142 patients experienced recurrent IC.
- Recurrence linked to smoking, coronary artery disease, prior laparotomy, and clopidogrel.
- Recurrent cases showed less typical symptoms like reduced hematochezia but higher transfusion needs.
Conclusions:
- Recurrent IC prevalence is 7.7%, associated with specific risk factors.
- Atypical presentations in recurrent IC may delay diagnosis.
- Further multicenter studies are needed to validate findings.

Introduction
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...

744
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

947
Introduction
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 is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
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...

01:17Irritable Bowel Syndrome I: Introduction
916
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
