Contrast evaluation of the pharynx and esophagus.
Swallowing requires the coordinated action of the alimentary tract from the oral cavity to the gastroesophageal junction. Any structural or functional abnormality along this pathway will interfere with swallowing. The "barium swallow" or pharyngoesophagogram requires examination of the oral cavity, pharynx, esophagus, and gastric cardia.
