Delayed small bowel perforation following blunt abdominal trauma: A case report and review of the literature.

We report a case of delayed presentation of a small bowel perforation following blunt abdominal trauma (BAT). An initial computed tomography (CT) scan revealed that the patient (a 32-year-old man) had a mesenteric hematoma, which was managed conservatively. Four weeks later, he returned to the hospital complaining of abdominal pain. A CT scan of the abdomen showed a thickened loop of the small bowel adjacent to the mesenteric hematoma at the level of the ileum. He was discharged home, but re-presented with acute abdomen 6 weeks post-trauma. An exploratory laparotomy was performed, which showed a perforated thickened loop of the ileum forming a phlegmon in the lower abdomen. In the English medical literature, only eight other reports of delayed post-traumatic presentation of ileal/jejunal perforation following BAT have been reported. We propose that post-traumatic intestinal perforation be considered in the differential diagnosis even in patients who experience a delayed small bowel perforation following BAT.
