Figure 10: A digitally captured fluoroscopic image is shown from a 7-year-old spayed female Beagle that presents with chronic regurgitation. Liquid barium and barium soaked kibble has been administered. The lower esophageal sphincter (LES) is seen to be displaced cranial to the diaphragm and into the thoracic cavity (white arrow) and is pulling the gastric cardia (CA) with it. Liquid barium is seen to reflux from the stomach into the thoracic esophagus (*) secondary to this Type I hiatal hernia.
