Zanatta R, Lemos RS, Pelegrini LF., Gastro-esophageal intussusception in a male German shepherd pup, Onl J Vet Res., 27 (8): 491-495, 2023. A 3-month-old male German shepherd pup presented with dyspnea due to suspected diaphragmatic hernia.  Radiography showed soft tissue at caudo dorsal mediastinum, ventral displacement of trachea and absence of gastric silhouette at cranial abdomen. Esophagography revealed dilated esophagus filled by positive contrast. In the caudal esophagus we observed soft tissue opacity with large filling defect. Gastric folds were outlined by positive contrast. Ultrasound showed spleen in thoracic cavity, congested liver and displaced stomach confirmed during surgery and repositioned. Gastropexy was performed and postoperative radiography confirmed reposition of stomach in cranial abdominal cavity, dilated esophagus filled by air with signs of aspiration pneumonia. Despite successful surgery, the patient died approximately 36 hours after surgery.  Findings suggest that radiographs cannot confirm this condition which appears similar to hiatal, peri-esophageal and diaphragmatic hernias. We  found ultrasonography superior to radiography for diagnosis and surgery.
