Esophageal stricture is typically caused by scar tissue that develops as a result of the following:

  • Ingestion of damaging substances, such as household cleaning agents
  • Treatment of esophageal varices —enlarged veins in the esophagus
  • Injuries caused by an endoscope—a thin, lighted tube used to see inside the body
  • Esophageal cancer
