Esophageal Rings and Webs


Esophageal rings and webs are bands of tissues around the esophagus causing restriction. Rings are thin and found in the lower esophagus. Webs are thicker, more fibrous though narrower and found in the upper esophagus.


  • Iron deficiency or anemia
  • Postcricoid cancer
  • Graft-versus-host disease caused by bone marrow transplant
  • Congenital factors

Symptoms are only occasional and do not occur everyday. They include:

  • Difficulty in swallowing
  • Food getting stuck in the throat
  • Spooning of nails or sunken nails


  • Iron supplements incase of anemia
  • Esophageal dilation to widen the narrow part of esophagus
  • Electrocautery to reduce the size of the ring through electric current

There is no way to prevent esophageal rings or webs.
