Esophageal Web
GASTROLAB/SCIENCE PHOTO LIBRARY
Rarely, webs develop in patients with untreated severe iron deficiency anemia; they develop even more rarely in patients without anemia.
Webs usually occur in the upper esophagus, causing dysphagia for solids. They are best diagnosed by barium swallow.
Some webs resolve with treatment of the anemia but can be easily ruptured during esophagoscopy.
