Abstract
A new entity causing lower esophageal obstruction, called “lower esophageal web,” has been described. Insufficient data regarding its true nature and pathology exist at this time. Similar x-ray findings may occur in (1) lower esophageal web, (2) short stricture or (3) “contractile esophageal ring” or “lower esophageal ring.” Endoscopy does not always confirm the differential diagnosis. Severely symptomatic cases deserve exploratory operation and surgical correction.
