Eosinophilic esophagitis is a chronic disease limited to the esophagus and has a persistent or spontaneously fluctuating course. So far it does not seem to limit life expectancy, but it often substantially impairs the quality of life. To date, there has been no association with malignant conditions, but there is concern that the chronic, uncontrolled inflammation will evoke irreversible structural alterations of the esophagus, leading to tissue fibrosis, stricture formation, and impaired function. This esophageal remodeling may result in several disease-inherent and procedure-related complications.
