RESUMEN
Blunt or penetrating trauma resulting in injury or rupture of the diaphragm is rare and constitutes about 1% to 3.9% of all thoraco-abdominal injuries. It is often regarded as a marker of severe trauma. Unfortunately about half of these injuries can be missed during the index admission. Contrast-enhanced computed tomography is the best modality to assess the extent, size of diaphragmatic defect and nature of hernial contents. Surgery is mandatory once the diagnosis is made to prevent future strangulation of hernial contents. Although technically challenging, laparoscopic reduction and mesh repair is feasible in expert hands. We report our experience with laparoscopic repair and mesh re-enforcement in a patient who had a large right diaphragmatic hernia with part of liver, gallbladder, small bowel and omentum within the right hemithorax secondary to a penetrating trauma he had incurred 29 years earlier.
