Ulcerative colitis (UC) can rarely affect the small intestine, presenting as ulcerative enteritis. This condition, distinct from Crohn disease, often appears post-colectomy and responds to standard inflammatory bowel disease therapies.
Area of Science:
- Gastroenterology
- Pathology
Background:
- Ulcerative colitis (UC) is a chronic colonic inflammatory disease with unknown causes.
- Small bowel involvement in UC is exceptionally rare, prompting diagnostic reconsideration.
Observation:
- A 38-year-old man developed severe diarrhea post-colectomy for UC.
- Histological examination revealed ulcerative enteritis with features mirroring UC.
Findings:
- This study reviews 11 additional cases of UC-associated enteritis (UCAE).
- UC-associated enteritis is distinct from Crohn disease.
- UCAE frequently manifests shortly after colectomy.
- UCAE typically responds to standard inflammatory bowel disease treatments.
Implications:
- Recognizing UCAE is crucial for accurate diagnosis and management.
- This entity expands the understanding of ulcerative colitis manifestations.
- Further research into the pathogenesis of UCAE is warranted.

Chronic Bowel Disorders: Introduction
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...
Inflammatory 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...
Inflammatory 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 transmural...
