A Right-Angled Thorn in the Bowel: A Curious Case of Small Bowel Perforation

We present a 45-year-old man with small bowel perforation resulting from the inadvertent ingestion of a right-angled thorn of the Gum Arabic plant (Vachellia nilotica). The diagnosis was made, and an emergency laparotomy was performed for suspected enteric peritonitis. The thorn was found projecting from the terminal ileum with a minimal intra-peritoneal fluid collection. The thorn was removed, and the perforation site was repaired primarily with absorbable sutures. The lack of a reliable history of foreign body ingestion makes it impossible to arrive at an accurate preoperative diagnosis in patients presenting with perforation peritonitis. Radiological investigations have a low sensitivity for detecting radiolucent vegetative foreign bodies as the cause of bowel perforations. Primary repair should be preferred over resection procedures in the management of foreign body-induced small bowel perforations.
