Cholestatic jaundice as an unusual presentation of a severe case of hiatal hernia in a dog

A 1‐year‐old, male French bulldog was presented with a 4‐week history of regurgitation, lethargy and weight loss. On examination, the dog was mildly dehydrated and had icteric mucous membranes. Advanced diagnostic imaging identified herniation of most of the stomach into the thorax through an enlarged oesophageal hiatus, displacing the proximal duodenum cranially and causing dynamic obstruction of the common bile duct. Surgical treatment of the hiatal hernia and the concurrent brachycephalic obstructive airway syndrome led to normalisation of laboratory findings and full resolution of clinical signs. Hiatal hernia should be considered a differential diagnosis in breeds predisposed to hiatal hernia presenting with jaundice.
