Barrett's Esophagitis |
|
Clinical Barrett's esophagus is an acquired condition where the normal stratified squamous lining of the distal esophagus undergoes metaplasia to columnar epithelium due to chronic gastroesophageal reflux and reflux esophagitis. The detection of Barrett's esophagus is important because it is believed to be a premalignant condition associated with a significantly increased risk of developing adenocarcinoma. Patients often present with a long-standing history of reflux symptoms or even dysphagia if they have developed peptic strictures. Between 20 to 40% of patients with Barrett's may exhibit no symptoms at all.
Radiological findings The classic radiologic
features of Barrett's consist of high esophageal strictures or deep, penetrating
ulcers that are also associated with a sliding hiatal hernia and gastroesophageal
reflux. The "high" location of these strictures and ulcers is
attributed to fact that they occur at the squamocolumnar junction in the
midesophagus. The presence of a delicate reticular mucosal pattern is
specific sign of Barrett's. They are often located adjacent to a stricture.
On contrast studies, they appear as tiny, barium-filled grooves/crevices
on the esophageal mucosa. If the disease has progressed so far as adenocarcinoma,
it may appear as a polypoid, ulcerating, infiltrating, or varicoid mass. |
