Barrett's esophagus is a condition in which the esophageal lining changes, becoming similar to the tissue that lines the intestine. A complication of gastroesophageal reflux disease (GERD), it is more likely to occur in patients who experienced GERD at a young age, had nighttime symptoms or had complications such as bleeding or stricture (a narrowing due to scarring).
There is a tendency to penetration, especially in Barrett’s syndrome. Accompanying disorders include hiatal hernia, dilatation of the oesophago-gastric junction and stricture above the junction, oesophageal ulcer and spasms, retrosternal pain, heartburn, dysphagia, vomiting, and gastrointestinal haemorrhage. Usually occurring in middle-aged and elderly persons. A rare disorder of unknown aetiology occurring in both congenital and acquired forms.
The condition was first described by Philip Rowland Allison in 1948.
