Answer

In cases of mild gastroesophageal reflux, diagnosis is made by clinical assessment and is confirmed by the response to therapy. Esophagography, conducted under fluoroscopic control, may reveal the integrity of esophageal peristalsis; however, it should not be used to assess the degree and severity of gastroesophageal reflux. Strictures can also be demonstrated by esophagography.

Chronic esophageal mucosal injury secondary to gastroesophageal reflux involves a mucosal/submucosal inflammatory cell infiltrate, as well as basal cell hyperplasia. In severe cases, this may appear as a ragged mucosal outline on radiography.
