Paraoesophageal hiatal herniation and pyloric obstruction were diagnosed in a puppy with a history of vomiting. Findings of contrast radiography included oesophageal reflux, delayed gastric emptying time, and paraoesophageal herniation. Exploratory celiotomy revealed increased firmness of the pylorus and a primary defect in the oesophageal hiatus, which allowed gastric herniation. Nissen fundoplication was performed following reconstruction of the oesophageal hiatus, and pyloroplasty was performed to relieve the gastric outlet obstruction. Pyloric biopsy findings were consistent with a diagnosis of chronic gastritis. Recovery from surgery was initially unremarkable; however, the dog died suddenly 3 weeks after surgery. PM examination showed a large diaphragmatic hernia adjacent to the oesophageal hiatus; the hernia had resulted in incarceration of the abdominal organs. The hiatal hernia reconstruction remained intact and was not the cause of the diaphragmatic disruption.
