e·soph·a·ge·al web

a congenital or acquired transverse fold of the mucous membrane and sometimes the deeper layers of the esophagus often causing dysphagia, usually in the lower half of the esophagus.

esophageal web

a thin membrane that may develop across the lumen of the esophagus, usually near the level of the cricoid cartilage. The abnormal condition is generally associated with iron deficiency anemia and usually disappears when the underlying problem is resolved. See also Plummer-Vinson syndrome.

esophageal web

A 2-3 mm in thickness stricture composed of mucosa and submucosa only, which is located anywhere along the length of the esophageal lumen; upper esophageal webs occur in the upper 2-4 cm of the esophagus, are lined by squamous epithelium, often associated with the Plummer-Vinson syndrome, and after yrs may evolve into postcricoid carcinoma; webs in the body of the esophagus may be multiple, represent embryonal remnants and may be associated with esophageal reflux; the lower esophageal web is a thin membrane marking the squamocolumnar junction and is seen in ±10% of normal subjects; symptomatic subjects may suffer intermittent dysphagia and impaction of a bolus of food Treatment Intraluminal balloon dilatation. See Café coronary.

Hypopharyngeal and proximal esophageal webs and strictures have become increasingly common with the increased use of concurrent chemo- and radiation therapy for head and neck malignancies.
Mechanical dysphagia is caused by a food bolus or foreign body, by intrinsic narrowing of the esophagus (from inflammation, esophageal webs, benign and malignant strictures, and tumors) or by extrinsic compression (from bone or thyroid abscesses or vascular tightening).
Benign esophageal stenosis caused by Schatzki rings (B rings) or by peptic strictures is the most common cause of food impaction, followed by esophageal webs, extrinsic compression, surgical anastomosis, esophagitis (eg, eosinophilic esophagitis), and motor disorders, such as achalasia.
25) There is also an association between cervical esophageal webs and gastroesophageal reflux.
Meant to be accessible and affordable, the atlas covers endoscopy techniques and normal anatomy; esophageal webs, rings, and strictures; hernia and gastroesophageal reflux disease; motility disorders of the esophagus; portal hypertension; ulcers; tumors; gastrojejunostomy; corrosive injury; uncommon inflammatory lesions; Mallory-Weiss syndrome; Dieulafoy's lesion; gastric antral vascular ectasia; foreign bodies; tracheoesophageal fistula; and miscellaneous issues.
DISCUSSION The association of postcricoid dysphagia, upper esophageal webs, and iron deficiency anemia is known as Plummer-Vinson syndrome (PVS) in the United States and Paterson-Brown Kelly syndrome in the United Kingdom.
The pathophysiology of esophageal webs is uncertain and a number of theories have been suggested.
He was found to have pill impaction requiring mechanical disimpaction related to an esophageal web and pseudodiverticulosis.
