Clinical, Radiographic and Pathological Features of Persistent Gastroesophageal Intussusception in an Adult Dog: A Case Report

The aim of this report is to describe the clinical, radiographic and pathological appearances of a persistent gastroesophageal intussusception in associated with idiopathic megaesophagus in an adult dog. A 6-years old, male Golden Retriever was referred for evaluation of chronic regurgitation and vomiting. Radiographic diagnosis of persistent gastroesophageal intussusception (GEI) with megaesophagus was made. Survey and contrast radiography evidenced a distension of the esophageal medial and caudal portions due to a dense soft-tissue mass and the barium cloud not pass to abdominal portion, where outlined the striations of muscle of the distal esophagus around the mass. Necropsy findings revealed a completed gastroesophageal intussusception with megaesophagus. Strangulation and incarceration of the whole stomach and intussusceptum resulted in detrimental effects on the cardiopulmonary system with vascular compromise of the intussuscepted organs. Histopathological results revealed tissue injury, circulatory disturbance and inflammatory reaction at dilated esophagus, affected lung and intussuscepted organs.
