Screening
Recommendations Regarding Endoscopy in Chronic Gastroesophageal Reflux Disease (GERD) Patients
- The main reason to evaluate patients with chronic GERD symptoms is to identify Barrett’s esophagus
- Patients with chronic GERD are the most at risk to develop Barrett’s esophagus and should undergo upper endoscopy
- Endoscopy to screen for Barrett’s esophagus is recommended in patients with >5 years of GERD symptoms
- Routine screening of GERD patients may not be appropriate in the Asian population because of the low prevalence of Barrett’s metaplasia in Asia
- Patients with alarm symptoms or high risk should be immediately referred for endoscopy to screen for malignancy or Barrett’s esophagus
- Alarm symptoms: Dysphagia, odynophagia, bleeding, weight loss
- Those who have had GERD symptoms of >3x/week for >20 years have 40-fold increased risk of developing adenocarcinoma
- Many patients who develop Barrett’s esophagus are asymptomatic
- 40% of patients with esophageal adenocarcinoma have no history of GERD
- Decision to screen should be individualized
Physical Examination
- Clinicians must examine the patient and look for any sign of extraesophageal disease, complications of advanced disease or any underlying disease that may manifest as GERD
Evaluation
Endoscopy
- Each upper endoscopy should record the squamocolumnar junction, the gastroesophageal junction (GEJ), presence of a hiatal hernia and the location of the diaphragmatic hiatus in patients suspected of Barrett’s esophagus
- The Asia-Pacific consensus defines the GEJ as the proximal limits of gastric folds
- Use Prague criteria in documenting extent of suspected Barrett’s esophagus on endoscopy
- Consider endoscopic screening in patients with or without history of reflux symptoms and with a family history of >2 first-degree relatives with Barrett’s esophagus or esophageal adenocarcinoma
- If initial endoscopy is negative, it is not recommended to repeat it; however, in patients with suspected Barrett’s esophagus and negative histology, endoscopy may be repeated in 1-2 years
