Bilateral Morgagni Hernia In A Donkey

This case report describes the clinical presentation and management of a donkey admitted with acute signs of abdominal pain that was diagnosed with a bilateral Morgagni hernia, a rare type of congenital diaphragmatic hernia. For more than 8 months before presentation, the donkey had been showing signs of recurrent mild abdominal pain that responded favourably to medical treatment. On admission, the donkey had mild tachycardia and tachypnoea. Radiography and ultrasound of the thorax and abdomen showed thoracic herniation of the large colon. Exploratory laparotomy was performed, and the sternal and diaphragmatic flexures of the large colon, as well as the left hepatic lobe, were found incarcerated in a bilateral Morgagni hernia. Intestine and liver were removed from the hernia, and the large colon was exteriorised. The defect in the diaphragm was repaired by stapling a polyester mesh circumferentially around the hernia ring and covering the mesh with an excised section of the greater omentum. No further complications and no recurrence of colic were observed during an 8-month follow-up period.
