Definition Return to top
Barrett's esophagus is a gastrointestinal disorder in which the lining of the esophagus (the tube that carries food from the throat to the stomach) is damaged by stomach acid that leaks backward.
See also: Gastroesophageal reflux disease (GERD)
Causes Return to top
Irritation of the lining of the esophagus by stomach acid can lead to Barrett's esophagus. The irritation is caused by stomach acid that leaks and moves back up the gastrointestinal tract. This is commonly known as gastroesophageal reflux (GERD) and it can cause heartburn.
Barrett's esophagus is more common in men than women. You have a greater risk for this condition if you have frequent and long-standing GERD.
Symptoms Return to top
Barrett's esophagus itself does not cause symptoms. The acid reflux that causes Barrett's esophagus results in symptoms of heartburn.
Exams and Tests Return to top
Diagnosis involves looking at the esophagus with an endoscope and obtaining a sample of esophagus tissue for examination. This procedure is called an esophagoscopy with biopsy.
Follow-up endoscopy is often advised to look for complications such as cancer.
Treatment Return to top
Treatment may be important even if you do not feel any symptoms.
Lifestyle changes include:
Medications to relieve symptoms and control gastroesophageal reflux include:
Surgery to remove a portion of the esophagus may be recommended, if a biopsy shows cell changes that tend to lead to cancer. Such changes are called dysplasia.
Photodynamic therapy (PDT) is an option that may allow you to avoid surgery. PDT involves the use of a special laser device, called an esophageal balloon, along with a drug called Photofrin. Together, the laser balloon and medication lead to destruction of the abnormal cells lining the esophagus, without affecting the normal tissue.
Outlook (Prognosis) Return to top
An increased risk of esophageal cancer is present. Follow-up endoscopy to look for dysplasia or cancer is often advised.
Possible Complications Return to top
Persons with this condition havean increased risk for esophageal cancer. If cancer develops, symptoms may include difficulty swallowing or weight loss. See: Esophageal cancer
When to Contact a Medical Professional Return to top
Call your health care provider if heartburn persists for longer than a few days, or you have pain or difficulty swallowing.
Call your provider if you have been diagnosed with Barrett's esophagus and your symptoms get worse or do not improve with treatment, or if new symptoms develop.
Prevention Return to top
Diagnosis and treatment of GERD may prevent Barrett's esophagus.
