Barrett's Esophagus: Diagnosis and Treatment
Barrett's esophagus is a change in the esophageal mucosa that develops due to prolonged exposure to acid from gastroesophageal reflux. This condition does not always cause significant symptoms, but requires regular monitoring to prevent potential complications. At the K+31 Clinic, gastroenterologists perform a thorough diagnosis and develop individualized treatment aimed at protecting the mucosa and maintaining esophageal health.

Symptoms
Barrett's esophagus often has no specific external manifestations, and its clinical picture is mainly caused by underlying gastroesophageal reflux disease. Classic symptoms that may indicate the presence of pathology include:
- Heartburn, which often worsens after eating or when lying down
- A burning sensation behind the breastbone
- Pain behind the breastbone, often resembling heart pain
- Sour belching
- Unpleasant taste in the mouth, especially after eating
- Regurgitation – the reflux of stomach contents into the mouth
- Discomfort or pain in the upper abdomen
- Frequent feeling of fullness in the stomach
As the condition progresses, dysphagia may develop – a symptom of Barrett's esophagus, characterized by difficulty swallowing food and a lump in the throat.
This is important. A prolonged asymptomatic course of the disease complicates timely diagnosis. This is why regular preventive examinations are necessary, especially if predisposing factors are present.
Diagnostics
The "gold standard" for diagnosing Barrett's esophagus is endoscopic examination, or gastroscopy. During the procedure, the doctor examines the mucosa using a flexible endoscope. To improve the accuracy of endoscopy, narrow-band imaging (NBI) technology is used, which allows for the highlighting of pathologically altered areas of the mucosa.
However, a definitive diagnosis is only established after a biopsy—the collection of tissue samples for histological examination. Upon detailed examination under a microscope, the specialist confirms the presence of columnar epithelium.
If the diagnosis is confirmed, the patient requires regular follow-up with endoscopic examinations at the intervals prescribed by the doctor. This is important for the dynamic assessment of the mucosa and the early detection of possible dysplasia.
In some cases, especially those with a high risk of esophageal cancer, additional diagnostic tests, including computed tomography (CT) and positron emission tomography (PET) scans, are recommended. These procedures can determine the extent of disease progression.
General information
Treatment
Treatment is aimed at preventing disease progression and the development of esophageal cancer. It includes monitoring the patient's condition, relieving symptoms of gastroesophageal reflux disease, and, in some cases, removing abnormal epithelium.
Controlling reflux helps slow or stop further damage to the esophageal mucosa. Patient management is always individualized and depends on the histological examination results. Conservative therapy includes:
- Drug therapy. The patient is prescribed proton pump inhibitors to suppress hydrochloric acid production in the stomach. These medications are taken long-term and strictly according to the doctor's recommended regimen.
- Lifestyle modifications. The patient is advised to lose weight if overweight, and avoid spicy, fatty, and acidic foods, coffee, chocolate, alcohol, and carbonated drinks. It is important to eat small meals, avoid lying down immediately after meals, and elevate the head of the bed while sleeping.
For severe dysplasia, endoscopic treatment is performed. The main methods are:
- Radiofrequency ablation is the most effective and well-studied method. During the procedure, a special electrode is inserted through an endoscope to the affected area of the mucosa. This electrode generates high-frequency radio waves. These waves cause controlled heating and destruction of only the affected layer of cells, while minimizing damage to healthy tissue.
- Argon plasma coagulation. This method involves delivering a high-frequency current to the tissue through argon gas. The mucous membranes coagulate superficially.
Surgical treatment of Barrett's esophagus may be performed if indicated. This involves resection of a portion of the esophagus, during which part of the organ is completely removed.

Definition and reasons
Barrett's esophagus is a change in the esophageal mucosa in which the squamous epithelium is replaced by the columnar epithelium typical of the lower gastrointestinal tract. This condition is a complication of long-standing gastroesophageal reflux disease (GERD).
The main cause of its development is the constant reflux of acidic stomach contents into the esophagus, or chronic reflux, which leads to damage and inflammation of the mucosa. As a protective response, the body replaces the damaged tissue with a more resilient type of epithelium.
This condition most often occurs in patients with a history of long-standing GERD. Furthermore, a number of factors that contribute to the prolonged and aggressive action of gastric contents on the esophageal mucosa predispose to the development of Barrett's esophagus. The main ones include:
Since Barrett's esophagus is considered a precancerous condition and increases the risk of developing esophageal adenocarcinoma, its timely detection and treatment are extremely important regular endoscopic monitoring.
