[Missed right post-traumatic diaphragmatic injuries: a review of six cases]

Right posttraumatic diaphragmatic injuries are rare; literature relates mainly isolated cases or small series and most often rupture are succeeding of blunt trauma. This series is interesting because the number of cases and the existence of two injuries following a right stab wound.

Retrospective study between January 2002 and September 2010. We collected the data of initial trauma, clinical, radiological, operative and follow-up for six patients supported for right posttraumatic diaphragmatic injuries.

All injuries were in late presentation. Four injuries were secondary to road traffic accident, and two after stab wound. The time to diagnosis was between 47 days and 15 years. Right posterolateral thoracotomy was the elective approach in the cases with diaphragmatic hernia (5 patients). In one case, video-assisted thoracoscopic surgery permits the diagnosis and repair of injury. Mortality was null and morbidity was present in one case from six. Follow-up ranging from 8 months and 42 months don't objectified complications.

Right diaphragmatic hernia is terrible sequelae after thoracoabdominal trauma. Surgery becomes more complex at this stage and can be done by thoracotomy. With strong suspicious signs at the first assessment of trauma, exploration by thoracoscopy can always avoid the occurrence of long-term sequelae.
