Penetrating Trauma to the Diaphragm

Recent use of minimally invasive techniques to evaluate the chest and abdomen in patients with penetrating thoracoabdominal trauma has led to the discovery of many occult diaphragm injuries. Surgical repair of these injuries is relatively straightforward. However, diagnosis can be difficult, and the natural history of these injuries is controversial. By developing a penetrating diaphragm injury model, the ultrasonographic characteristics and natural history of this injury can be better understood.
