Barrett's Esophagus
What is Barrett's esophagus?
Barrett's esophagus is a condition in which there are changes in the cells of the lining of the esophagus. These changes occur as a result of chronic GERD (gastroesophageal reflux disease). Barrett's esophagus is a precancerous condition that, left untreated, may lead to a dangerous type of cancer called esophageal adenocarcinoma. What causes Barrett's esophagus?
Barrett's esophagus occurs when acid exposure causes the protective cells lining the esophagus to break down and undergo genetic changes that set the stage for cancer. How is Barrett's esophagus diagnosed?
An endoscopic examination is required to diagnose Barrett's esophagus. During this procedure the patient is sedated. The physician examines the lining of the esophagus and stomach with an endoscope - a thin, lighted, flexible tube. Biopsies are performed, taking pieces of the abnormal tissue to examine under a micrscope. |
