Duodenojejunal Flexure Perforation Following Blunt Abdominal Trauma: A Series of Three Surgically Confirmed Cases

Duodenojejunal (DJ) flexure perforation due to blunt abdominal trauma is a relatively uncommon condition, but it carries significant morbidity and mortality. Such cases are challenging to diagnose due to their subtle presentation and retroperitoneal location. This case series presents three surgically confirmed cases of DJ flexure perforation, each demonstrating distinct radiological findings on Contrast-Enhanced Computed Tomography (CECT). Key imaging features included free intraperitoneal air, bowel wall thickening, mesenteric fat stranding, and intramural haematoma. The cases underscore the importance of maintaining a high index of suspicion in trauma patients with vague abdominal symptoms. Early identification of these radiological signs led to timely surgical interventions, resulting in favourable outcomes. Through detailed imaging and clinical correlation, this series provides valuable insights for radiologists and emergency clinicians, emphasising the critical role of CECT in diagnosing traumatic bowel perforations at anatomically complex regions like the DJ flexure. Improved awareness and interdisciplinary coordination can significantly enhance early detection and reduce complications from delayed treatment.
