1. Perforation of the anterior wall of the duodenum will often present with free air and fluid in the peritoneal cavity, whereas perforation involving the posterior wall will often have walled-off fluid collections in the retroperitoneum. 2. Duodenal diverticula are important to identify prior to attempting endoscopic retrograde cholangiopancreatography and may have complications (inflammation, perforation, bezoar formation). 3. Like pancreatic injuries, duodenal injuries rarely occur in isolation and the presence of one injury should prompt a more thorough evaluation for coexisting injuries (solid organs, lumbar spine, and vascular) as these coexisting injuries are associated with significantly increased morbidity and mortality.
