Traumatic perforated duodenal diverticulum after a fight, a case report.

Introduction: Fewer than 200 cases of Perforated Duodenal Diverticulum ("PDD") have been reported in the literature. The percentage of caused by trauma is generally very low and similar to rates recorded for duodenal injuries caused by trauma in the absence of diverticula (3 %-5 %). As a rare cause of abdominal pain after trauma, perforated duodenal diverticula are seldom diagnosed preoperatively.
