Barrett's esophagus is a disorder in which the lining of the esophagus (the tube that carries food from the throat to the stomach) is damaged by stomach acid and changed to a lining similar to that of the stomach.
When you eat, food passes from your throat to your stomach through the esophagus (also called the food pipe or swallowing tube). Once food is in the stomach, a ring of muscles keeps it from leaking backward into the esophagus.
If these muscles do not close tightly, stomach acid can leak back into the esophagus. This is called reflux or gastroesophageal reflux.
Reflux may cause symptoms of heartburn. It may also damage the lining of the esophagus. The esophagus lining then changes in appearance and looks like the stomach lining (Barrett's esophagus).
Barrett's esophagus occurs more often in men than women. You are more likely to have this condition if you have had GERD for a long time.
Patients with Barrett's esophagus may develop more changes in the esophagus called dysplasia. When dysplasia is present, the risk of getting cancer of the esophagus increases.
Barrett's esophagus itself does not cause symptoms. The acid reflux that causes Barrett's esophagus often leads to symptoms of heartburn. However, many patients with this condition do not have symptoms.
If GERD symptoms are severe or they come back after you have been treated, the doctor may perform an endoscopy.
People with Barrett's esophagus have an increased risk for esophageal cancer. Still, only a small number of people with Barrett's esophagus develop cancer. Your health care provider may recommend a follow-up endoscopy to look for changes that may lead to cancer (dysplasia), or for cancer itself.
TREATMENT OF GERD
Treatment should improve acid reflux symptoms, and may keep Barrett's esophagus from getting worse. Treatment may involve lifestyle changes and medications such as:
Lifestyle changes, medications, and anti-reflux surgery may help with symptoms of GERD, but will not make Barrett's esophagus go away.
TREATMENT OF BARRETT'S ESOPHAGUS
Surgery or other procedures may be recommended if a biopsy shows cell changes that are very likely to lead to cancer. Such changes are called severe or high-grade dysplasia.
Some of the following procedures remove the harmful tissue in your esophagus, where the cancer is most likely to develop.
Treatment should improve acid reflux symptoms and may keep Barrett's esophagus from getting worse. None of these treatments will reverse the changes that may lead to cancer.
Call your health care provider if:
Diagnosis and treatment of GERD may prevent Barrett's esophagus.
