Multiple ileal perforations due to regular diclofenac sodium injections: a case report.

BACKGROUND

Although the adverse effects of non-steroidal anti-inflammatory drugs (NSAIDs) on the upper gastrointestinal tract have been well characterized, those specific to the lower gastrointestinal tract are less clear, as only a limited number of articles and case reports exist in the literature.

CASE PRESENTATION: We describe a case of a 69-year-old woman who presented to the emergency department due to sudden onset abdominal distension and pain. Notably, she reported using intramuscular diclofenac sodium twice daily for 14 days after knee joint replacement surgery. The patient denied any other coexisting diseases. As a subsequent X-ray and computed tomography (CT) scan showed free air in the abdomen, an exploratory laparotomy was performed, revealing four free perforations in the terminal ileum. Findings on microscopic analysis were non-specific.

CONCLUSION

We report a unique case of multiple ileal perforations due to regular diclofenac sodium injections and contend that ileal perforation can be considered as a source for pneumoperitoneum with concomitant peritonitis in patients with a history of NSAID use if other possibilities are excluded.
