Barrett's Esophagus
What is Barrett's esophagus? Barrett’s esophagus is a change in the tissue lining your esophagus, the tube in your throat that carries food to your stomach. For reasons no one understands completely, cells in the esophageal lining sometimes become more like intestinal cells. Researchers suspect that having acid reflux or gastroesophageal reflux disease (GERD) is related to Barrett’s esophagus. Barrett’s esophagus raises the risk of developing a rare esophageal cancer.
Who gets Barrett’s esophagus? People who are more likely to develop Barrett’s esophagus: Are non-Hispanic white. Were assigned male at birth. Are middle-aged or older. Have obesity. They may also have: Family history of Barrett’s esophagus or esophageal cancer. Heartburn symptoms for 10-plus years. Gastroesophageal reflux disease (GERD).
How common is Barrett’s esophagus? On its own, Barrett’s esophagus doesn’t produce symptoms. You may discover you have it only after seeing your healthcare provider for gastroesophageal reflux disease (GERD) symptoms or after developing esophageal cancer. Because of the lack of symptoms, no one is sure how common it is. But experts estimate that Barrett’s esophagus affects about 1% of people.
What causes Barrett’s esophagus?
Multiple factors contribute to
Barrett’s esophagus. It’s more common in people with GERD. This chronic
(ongoing) condition occurs when stomach contents flow backward into the
esophagus. Experts believe the acidic liquid irritates the lining of the
esophagus, leading to changes in the tissue. But you can also have Barrett’s
esophagus without having GERD.
What are the symptoms of Barrett’s
esophagus?
Barrett’s esophagus does not cause
symptoms. But you can watch for signs of the conditions it’s associated with —
heartburn and acid regurgitation.
Heartburn that occurs at least twice
a week is the biggest red flag. Heartburn symptoms include a burning sensation
in the chest and vomit in the back of the throat (acid regurgitation).
Other symptoms to watch for include:
Heartburn that worsens or wakes you
from sleep.
Painful or difficult swallowing.
Sensation of food stuck in your
esophagus.
Constant sore throat, sour taste in
your mouth or bad breath.
Unintentional weight loss.
Blood in stool.
Vomiting.
How is Barrett's esophagus
diagnosed?
The only way to confirm the
diagnosis of Barrett's esophagus is with a test called an upper endoscopy. This
involves inserting a small lighted tube (endoscope) through the throat and into
the esophagus to look for a change in the lining of the esophagus.
While the appearance of the
esophagus may suggest Barrett's esophagus, the diagnosis can only be confirmed
with small samples of tissue (biopsies) obtained through the endoscope. A
pathologist will examine the tissue to make the diagnosis.
How is Barrett’s esophagus treated?
Your treatment depends largely on
presence of symptoms and dysplasia on biopsies:
Barrett’s esophagus without
dysplasia
Having Barrett’s esophagus without
dysplasia means your provider didn’t detect precancerous cells. Usually, you
don’t need treatment at this stage. But your healthcare provider will want to
monitor the condition. You’ll need to have an upper endoscopy every two to three
years.
If you have GERD, your healthcare
provider may prescribe medications to treat GERD. These medicines decrease
stomach acid, which can protect your esophagus from damage. Lifestyle changes,
like sleeping slightly inclined and avoiding eating dinner late, often help,
too.
Barrett’s esophagus with dysplasia
Dysplasia is the presence of
precancerous cells. Your doctor may recommend frequent monitoring or treatment
to prevent cancer from developing.
Low-grade dysplasia
Low-grade dysplasia means you have
some abnormal cells, but the majority aren’t affected. In this case, you may
just need frequent checks to see if more changes occur. Expect to undergo an
upper endoscopy every six months to a year. Ablation therapy is also
recommended in select patients.
High-grade dysplasia
High-grade dysplasia indicates a
substantial change in your esophagus lining. With this diagnosis, cancer is
more likely. You may need to repeat upper endoscopies more often to look for
cancer. Your provider may also recommend treatment, which focuses on removing
the damaged tissue and includes:
Radiofrequency ablation: This is the
most common procedure. It burns off abnormal tissue using radio waves, which
generate heat.
Cryotherapy: Healthcare providers
use liquid nitrogen to freeze diseased parts of the esophagus lining so it will
slough off (shed). The process is similar to how dermatologists “freeze off” a
wart.
Endoscopic mucosal resection: Using
an endoscope, your provider can remove precancerous spots on the esophagus
lining.
Surgery: If you have severe
dysplasia or esophageal cancer, your provider may recommend an esophagectomy, a
surgery to remove all or part of the esophagus.
