Gastroesophageal intussusception in a Labrador retriever.

A 14-month-old, intact male Labrador retriever was referred for evaluation of vomiting and regurgitation. A diagnosis of gastroesophageal intussusception with aspiration pneumonia was made. The patient responded favorably to aggressive surgical and medical management. The guarded to poor prognosis for gastroesophageal intussusception makes the successful outcome of this case unique.
