Injury
-
In the examination of patients with severe thoracic and/or abdominal trauma not requiring surgical exploration, special attention should be given to signs of traumatic diaphragmatic herniation (TDH). We analysed the hospital records of 63 patients with traumatic injuries of the diaphragm. Of these patients, 39 had suffered a blunt trauma in a traffic accident, 21 penetrating trauma, and three had fallen from a great height. ⋯ If diaphragmatic injury is suspected, ultrasound investigation must be performed. If the physician is still in doubt, computed tomography should be performed. At laparotomy, the diaphragm should always be thoroughly examined for lacerations.

Rupture of the diaphragm occurs in approximately 5 per cent of cases of severe blunt trauma to the trunk, and the mortality may be as high as 50 per cent. The diagnosis is important because of the high incidence of associated organ damage and complications of a missed injury. Successful diagnosis requires a high index of suspicion but can be made from the chest radiograph in 90 per cent of cases if visceral herniation has occurred. We present three cases of rupture of the diaphragm which highlight the frequent occurrence of a delayed or missed diagnosis.
