Abstract
The incidence of pharyngoesophageal webs in 100 unselected patients with a large variety of gastrointestinal symptoms and in autopsy observations of 50 unselected cases was 8 and 16 per cent, respectively. Histologic studies revealed that the webs observed on autopsy consisted of transverse folds of normal mucosa and submucosa. There were no muscular atrophy, keratinization, or inflammatory changes observed as are seen in the classic Plummer-Vinson syndrome. Esophageal webs appear to be common in a hospital population. This type of web is probably of no clinical significance as it produces no clinical symptoms. The incidence and clinical significance of 2 other structures of the pharyngoesophagus, the postcricoid impression and the cricopharyngeal indentation, are briefly discussed.
