Although diverticulum of the esophagus occurs more often than we are led to believe from the number of cases reported, it is a comparatively rare condition.

Diverticula which do not produce symptoms apparently may occur at almost any point in the esophagus and may be caused by an increase in the intra-esophageal pressure or, more likely, by some tractive force from the outside.
