Introduction: Early diagnosis and treatment of injuries of the diaphragm are important both because of high incidence of concomitant injuries and since they may lead to life-threatening intestinal and gastric strangulation in the late term. Herein, cases with diaphragmatic injury that have been diagnosed and operated in the early period after injury or during surgery were presented. Methods: Data of 14 cases, which have been diagnosed with diaphragmatic injury after trauma or during surgical procedure that was performed because of concomitant abdominal or intra-thoracic injury between January 2008 and April 2013, were retrospectively reviewed. Results: Of the traumatic diaphragmatic injuries, 10 (71.4%) have occurred due to penetrating trauma, whereas 4 (28.5%) have occurred due to blunt trauma. Diagnosis was made using I.V. contrast-enhanced whole abdominal and thoracic tomography in all 3 pediatric cases (21.4%) and during surgery in the others (78.5%). Conclusion: All of the diaphragmatic injuries have been accompanied by intra-abdominal or intra-thoracic organ injury that requires surgery. In these cases, the diagnosis was made on suspicion of diaphragmatic injury in the course of surgical procedure performed for concomitant organ injury. Computed tomography was diagnostic for diaphragmatic injuries in the pediatric cases.
