Chronic traumatic diaphragmatic hernia.
Chronic traumatic diaphragmatic hernia is an uncommon but persistent diagnosis associated with significant morbidity and mortality. Chronic TDH describes a spectrum of disease in antecedent mechanism of injury, timing of presentation, size of diaphragmatic defect, and amount and type of tissue displaced into the chest. Multiplanar CT with coronal, sagittal, and axial reconstruction is most effective in making this diagnosis. Once diagnosed, repair should be undertaken. Although transabdominal approaches may be successful, the authors prefer an open transthoracic approach, recognizing that either approach may need to incorporate access into the other body cavity to complete the repair. Basic hernia principles apply including the construction of a tension-free repair, which may necessitate the use of prosthetics. As surgeons become increasingly comfortable with minimally invasive techniques, more chronic TDH are likely to be approached in this fashion. Finally, as much of the morbidity and mortality is associated with the catastrophic consequences of chronic TDH, vigilance needs to be applied in an attempt to diagnose and then repair TDH while in the latent stage prior to the development of the catastrophic complications that herald the obstructive stage.
