Oesophageal Web

21 yo female with dysphagia. Barium swallow shows circumferential radiolucent ring in upper esophagus. Proximal dilatation and jet phenomenon (Barium spurting through the ring on fluoroscopy) indicate partial obstruction.
Esophageal web:
A thin ring-like mucosal constriction projecting into the lumen
10% incidence at autopsy
Can be congenital or acquired
Most in hypopharynx and proximal esophagus
Majority protrude from anterior esophageal wall
Symptoms if lumen > 50% compromised
Sideropenic dysphagia (Plummer-Vinson syndrome)
-Iron deficiency anemia
-Esophageal web with dysphagia
-Increased incidence of carcinoma
If symptomatic, balloon dilatation; bougienage during esophagoscopy.
