Perforated gastric ulcer v associated with pyloroplasty for chronic hypertrophic pyloric gastropathy in a dog

A six-year-old male silkie terrier presented with a history of chronic vomiting. A diagnosis of gastric outflow obstruction was made using contrast radiography of the upper gastrointestinal tract. Surgical examination of the stomach revealed thickened pyloric antral mucosa. A Heineke-Mikulicz pyloroplasty combined with resection of the hypertrophic pyloric mucosa were performed to increase the patency of the pyloric lumen. The dog recovered well from surgery and his condition remained stable until the sixth day postoperatively when his condition deteriorated rapidly resulting in his death that night. At autopsy a perforated gastric ulcer was found in the cardiac region of the pylorus with evidence for a generalised peritonitis. An association between gastric outflow obstruction and gastric ulceration has been reported in human clinical literature and in canine experimental models. No such association has been previously documented in the veterinary clinical literature.
