Small bowel injury in low-dose aspirin users

Area of Science:

• Gastroenterology
• Pharmacology
• Internal Medicine

Background:

• Low-dose aspirin (LDA) is linked to upper gastrointestinal complications like ulcers and bleeding.
• Recent focus has shifted to aspirin's adverse effects on the small intestine, aided by advanced endoscopy.

Purpose of the Study:

• To review the impact of LDA on small bowel mucosa.
• To discuss the clinical implications and potential management strategies for aspirin-induced enteropathy.

Main Methods:

• Review of preliminary capsule endoscopy (CE) studies and other relevant literature.
• Analysis of findings regarding mucosal inflammation and lesions in the small bowel.

Main Results:

• Short-term LDA use can cause mild small bowel inflammation.
• Chronic LDA use leads to various small bowel lesions, including erosions and ulcers, potentially causing strictures.
• Enteric-coated aspirin may be more detrimental to the small bowel than buffered aspirin.

Conclusions:

• LDA significantly impacts the small bowel, necessitating further research into its effects.
• Novel therapeutic approaches are crucial for managing aspirin-induced enteropathy, especially since discontinuing LDA can increase cardiovascular risks.
