Phrenic ampulla

Last revised by Dr Henry Knipe on 01 Jun 2020

The phrenic ampulla (also known as the esophageal vestibule) is the region between the A-ring and B-ring of the distal esophagus. The gastro-esophageal junction is below the ampulla (and gastric folds should not enter the region of the ampulla).

Differential diagnosis

The ampulla is more prominent in some patients than in others, but it is a normal finding and should not be confused with a sliding hiatal hernia or an esophageal web.
