Bilateral Morgagni hernia in a donkey.

This case report describes the clinical presentation andmanagement of a donkey admitted with acute signs ofabdominal pain that was diagnosed with a bilateral Morgagnihernia, a rare type of congenital diaphragmatic hernia. Formore than 8 months before presentation, the donkey had beenshowing signs of recurrent mild abdominal pain that respondedfavourably to medical treatment. On admission, the donkeyhad mild tachycardia and tachypnoea. Radiography andultrasound of the thorax and abdomen showed thoracicherniation of the large colon. Exploratory laparotomy wasperformed, and the sternal and diaphragmatic flexures of thelarge colon, as well as the left hepatic lobe, were foundincarcerated in a bilateral Morgagni hernia. Intestine and liverwere removed from the hernia, and the large colon wasexteriorised. The defect in the diaphragm was repaired bystapling a polyester mesh circumferentially around the herniaring and covering the mesh with an excised section of thegreater omentum. No further complications and no recurrenceof colic were observed during an 8-month follow-up period.
