Radiologic evaluation of the esophagus: methods and value in motility disorders and GERD.
The barium esophagram is an essential component in the workup of a patient with dysphagia and gastroesophageal reflux disease, especially when considering antireflux surgery or after such surgery. The examination requires a flexible approach with an emphasis on the motility portion of the examination. When properly performed, the examination should identify the following: normal or impaired esophageal emptying; normal or abnormal motility; the presence and type of hiatal hernia; the presence of a distal stricture or mucosal ring; and in many instances, the presence of gastroesophageal reflux. In patients after antireflux surgery, the examination should identify the following: normal of impaired esophageal emptying; normal or abnormal motility; the location, tightness, and length of the fundoplication; the presence of a recurrent hernia; and the presence of gastroesophageal reflux.
