Heartburn

A burning sensation in the upper abdomen and chest. Also known as acid indigestion, heartburn is most common in older people and pregnant women. Burning chest pain is sometimes accompanied by a bitter or sour taste in the back of the throat. Heartburn is the most common symptom of ESOPHAGEAL REFLUX (the backward flow of acid from the stomach up into the esophagus). Simple modifications in lifestyles can control most cases of heartburn. Doctors recommend avoiding foods and beverages that contribute to the problem (such as spicy or greasy foods, chocolate, coffee, and alcohol); not smoking; losing a few pounds if overweight; and not eating 2 to 3 hours before going to bed. Over-the-counter antacids may also provide relief. If these measures prove insufficient, or if it is necessary to take antacids very frequently (more than 3 or 4 times a day), it is important to see a physician. Patients who experience esophageal reflux at a group age, had nighttime symptoms, or had complication such as bleeding or a narrowing due to scaring may be of higher risk of developing esophageal cancer. Based on severity of symptoms esophageal reflux may require further treatment with prescription medication. In severe

Am I at Risk for Esophageal Cancer?
There are two types of esophageal cancer: squamous cell cancer and adenocarcinoma of the esophagus. Squamous cell cancer occurs most commonly in people who smoke cigarettes and drink alcohol excessively. This type of cancer is not increasing in frequency. Adenocarcinoma of the esophagus is increasing in frequency and is associated with gastroesophageal reflux disease (GERD). The most common symptom of GERD is heartburn, a condition that 20 percent of American adults experience at least twice a week. Although these individuals are at increased risk of developing esophageal cancer, the vast majority of them will never develop it. But in a few patients with GERD (estimates vary from 1 percent to 12 percent), a change in the esophageal lining develops, a condition called Barrett's esophagus. Doctors believe most cases of adenocarcinoma of the esophagus begin in Barrett's tissue.

What is Barrett's Esophagus?
Barrett's esophagus is a condition in which the esophageal lining changes, becoming similar to the tissue that lines the intestine. A complication of GERD, it is more likely to occur in patients who experienced GERD at a young age, had nighttime symptoms or had complications such as bleeding or stricture (a narrowing due to scarring). Dysplasia, a precancerous change in the tissue, can develop in Barrett's tissue. Barrett's tissue is visible during endoscopy, although a diagnosis by endoscopic appearance alone is not sufficient. The definitive diagnosis of Barrett's esophagus requires biopsy confirmation.

How Does my Doctor Test for Barrett's Esophagus?
Your doctor will first perform an upper endoscopy to diagnose Barrett's esophagus. Barrett's tissue has a different appearance than the normal lining of the esophagus and is visible during endoscopy. Although this examination is very accurate, your doctor will take biopsies to search for dysplasia, a pre-cancerous change in the Barrett's tissue that is not visible to the endoscopist. Taking biopsies from the esophagus through an endoscope only slightly lengthens the procedure time, causes no discomfort and rarely causes complications. Your doctor can usually tell you the results of your endoscopy after the procedure, but you will have to wait a few days for the biopsy results.

Who Should be Screened for Barrett's Esophagus?
Barrett's esophagus is twice as common in men as women. It tends to occur in middle-aged Caucasian men who have had heartburn for many years. There's no agreement among experts on who should be screened. Even in patients with heartburn, Barrett's esophagus is uncommon and esophageal cancer is rare. One recommendation is to screen patients older than 50 who have had significant heartburn or required regular use of medications to control heartburn for several years. If that first screening is negative for Barrett's tissue, there is probably no need to repeat it.

How is Barrett's Esophagus Treated?
Medicines and surgery can effectively control the symptoms of GERC. However, neither medications nor surgery can reverse the presence of Barrett's esophagus or the risk of cancer. There are some experimental treatments through which the Barrett's tissue can be destroyed through the endoscope; but these treatments can cause complications, and their effectiveness in preventing cancer is not clear.

What is Dysplasia?
Dysplasia is a precancerous condition that doctors can only diagnose by examining biopsy specimens under a microscope. Doctors subdivide the condition into high-grade, low-grade, or indefinite for dysplasia. If dysplasia is found on your biopsy, your doctor might recommend more frequent endoscopies, attempt to destroy the Barrett's tissue, or esophageal surgery. Your doctor will recommend an option based on the degree of the dysplasia and your overall medical condition.
If I Have Barrett's Esophagus, How Often Should I Have an Endoscopy to Check for Dysplasia?
The risk of esophageal cancer in patients with Barrett's esophagus is quite low, approximately 0.5 percent per year (or 1 out of 200). Therefore, the diagnosis of Barrett's esophagus should not be a reason for alarm. It is, however, a reason for periodic endoscopies. If your initial biopsies don't show dysplasia, endoscopy with biopsy should be repeated about every 1 to 3 years. If your biopsy shows dysplasia, your doctor will make further recommendations.
