This study aimed to investigate whether NSAIDs can cause damage to the small bowel mucosa. Among the 273 subjects, 125 (45.8%) had small bowel erosions or ulcers, with NSAIDs identified as an independent risk factor for these injuries. Antithrombotic agents were not found to cause or exacerbate damage to the small bowel in this study.
Background Currently, because the population is aging, use of medications has been increasing, including use of nonsteroidal anti-inflammatory drugs (NSAIDs) and antithrombotic agents. Aims This study aims to investigate whether NSAIDs can cause damage to the small bowel (SB) mucosa. Methods Endoscopic videos of subjects who had undergone capsule endoscopy (CE) were evaluated by three experts in order to identify SB injury. All medications taken within 2 weeks from the time of CE were investigated. Cases with a final diagnosis of intestinal tuberculosis, inflammatory bowel disease, Behcet's disease, Peutz-Jeghers syndrome, small bowel lymphoma, or Henoch-Schonlein purpura were excluded from the analysis. Results Among the 273 subjects, 125 (45.8%) had SB erosions or ulcers (erosion group) and the remaining 148 (54.2%) did not (no erosion group). SB erosions or ulcers were more common in females, patients aged > 60 years, and subjects taking NSAIDs (p = 0.048, 0.032, and < 0.001, respectively). No statistically significant differences were found between the two groups in the following variables: history of cancer and GI surgery, reasons for the test, comorbidities, and use of anticoagulants and antiplatelet agents. Multivariate analysis showed that use of NSAIDs [OR 4.191 (95% CI 1.858-9.458),p < 0.001] was an independent risk factor for SB erosions or ulcers. Conclusions Use of NSAIDs is the only independent risk factor for SB injury identified in this study. Antithrombotic agents do not cause or exacerbate damage to the SB, according to our results.
