title: Diaphragmatic Hernia of the Stomach with Gastric Rupture in a Domestic Pig.
abstract: A 5.5-mo-old castrated, male Red Duroc pig presented acutely with depression and abdominal pain 9 d after an altercation with another pig. A CT examination indicated right pneumothorax and herniation of the stomach into the thoracic cavity. Due to a poor prognosis, the pig was euthanized. A necropsy and gross examination revealed a tear of the diaphragmatic muscle in the region of the esophageal hiatus through which the stomach was displaced into the right side of the thoracic cavity. In addition, the herniated stomach had a rupture of the stomach wall through which the gastric mucosa was everted and exposed into the right thoracic cavity. The right thoracic cavity had acute fibrinous pleuritis, and the right lung was collapsed. CT scans performed every 1 to 2 wk for 2 mo prior to the pig's death did not reveal any abnormalities in the diaphragm. Trauma was considered the most likely cause of the diaphragmatic tear and subsequent herniation and rupture of the stomach.
