Plain-English summary
A 16-month-old dog was brought to the vet because it had been vomiting a lot, not eating at all, losing weight, and passing dark, tarry stools. During surgery, the vet found that a large number of eosinophils (a type of white blood cell) had built up in the area where food leaves the stomach, causing a blockage. The vet removed the affected part of the stomach, which successfully resolved the problem. This case shows that eosinophilic gastritis (inflammation of the stomach due to eosinophils) should be considered when diagnosing similar issues in dogs. The treatment worked well, and the dog recovered.
Abstract
A 16-month-old dog was presented with chronic vomiting, anorexia, progressive weight loss, and melena. Exploratory laparotomy revealed a massive pyloric eosinophilic infiltration leading to pyloric obstruction that was treated successfully with pylorectomy. This is a novel clinical presentation of eosinophilic gastritis and highlights the need to consider it as a differential diagnosis for pyloric obstruction.
