Small bowel ulcers: when is it not inflammatory bowel disease ?

Area of Science:

• Gastroenterology
• Internal Medicine
• Diagnostic Medicine

Background:

• Small bowel endoscopy reveals ulcers in a significant number of patients.
• While inflammatory bowel disease (IBD) is a common attribution, ulcers can be unspecific or indicate other conditions.

Purpose of the Study:

• To review recent literature on the differential diagnosis of small bowel ulcers.
• To highlight the challenges in differentiating causes of small bowel ulcers.

Main Methods:

• Literature review of recent studies on small bowel ulcers.
• Analysis of diagnostic approaches and differentiating factors.

Main Results:

• NSAID enteropathy is a primary differential diagnosis for IBD in small bowel ulcers.
• Intestinal tuberculosis and rare causes like autoinflammatory, neoplastic, vascular, or nontuberculous infections should be considered.
• Morphology and histology are often non-specific; diagnosis relies on history, clinical symptoms, laboratory tests, and genetic testing for rare entities.

Conclusions:

• Diagnosis of small bowel ulcers requires a comprehensive approach.
• Integrating endoscopic findings with patient history, histology, imaging, and laboratory tests is crucial due to overlapping appearances.
