Selective IgA deficiency can cause recurrent intestinal obstruction, even without anatomical blockages. This diagnosis should be considered in patients with unexplained, recurring bowel obstructions.
Area of Science:
- Gastroenterology
- Immunology
Background:
- Recurrent intestinal obstruction can present diagnostic challenges.
- Identifying underlying causes is crucial for effective patient management.
Observation:
- A 32-year-old woman experienced recurrent small bowel obstructions.
- Initial investigations including CT scans and biopsies were inconclusive.
- Imaging revealed changes suggestive of post-inflammatory processes.
Findings:
- The patient was diagnosed with selective IgA deficiency.
- This deficiency was linked to recurrent infections in the terminal ileum.
- These infections led to the observed intestinal obstructions.
Implications:
- Selective IgA deficiency is a potential cause of recurrent intestinal obstruction.
- Consider immunological evaluation in cases of unexplained bowel obstruction.
- Early diagnosis can prevent complications and guide treatment.

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...

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...
