Traumatic diaphragmatic hernia: tertiary centre experience.

BACKGROUND

Traumatic diaphragmatic hernia (TDH) resulting from traumatic diaphragmatic rupture (TDR) may not be easily detected and can lead to significant morbidity and mortality.

PATIENTS AND METHODS

A retrospective case note analysis was performed of all patients treated for TDR at a major teaching hospital between March 2003 and March 2008. The aetiological factors, associated injuries, management and outcome were analysed.

RESULTS

Twenty-seven patients were studied (24 males, 3 females) and their ages ranged from 16 to 72 years (median 35 years). TDR was left-sided in 85% and right-sided in 15%. Aetiology was blunt trauma in 81% and 19% had penetrating injury. Associated injuries were present in 81%. The most common approach for repair was transabdominal (89%); additional thoracotomy was needed in 11%. Herniation of abdominal contents was present in 85% and herniation of more than one organ was present in 57%. The diaphragmatic rent was repaired primarily in 89% using nonabsorbable sutures. Post-operative pulmonary complications occurred in 52% of patients. Three patients (11%) died.

CONCLUSION

Left-sided blunt traumatic diaphragmatic rupture was more common than right-sided rupture. The most commonly herniated organs were the stomach and colon. Most ruptures could be repaired by an abdominal approach, which also allowed a complete exploration of the abdominal organs. Careful attention should be given to associated intra-abdominal injuries. Most of the defects were repaired directly using nonabsorbable sutures.
