Tension gastrothorax secondary to trauma in the emergency room: A case report.

In tension gastrothorax, the abdominal contents are displaced into the thorax, leading to a mediastinal shift that arises from the pressure placed on the intrathoracic region. This condition is often due to a congenital or acquired (secondary to surgery) diaphragmatic defect and is rarely seen secondary to trauma. A 40-year-old man presented to the emergency department after an in-vehicle traffic accident. He had no active complaint other than mild chest pain. On auscultation, breath sounds were audible in the left lung base and bowel sounds were heard. Computed tomography of the thorax revealed left-sided diaphragmatic hernia. The jugular vein was distended, and the patient became desaturated in the emergency room. Nasogastric decompression was performed, and the saturation improved. The patient underwent open surgery. Traumatic tension gastrothorax should be considered in the differential diagnosis of acute-onset severe respiratory failure. It can be diagnosed by rapid clinical and radiological evaluation.
