-Typical GERD symptoms that persist despite a therapeutic trial of 4 to 8 weeks of twice-daily PPI therapy.
-Severe erosive esophagitis after a 2-month course of PPI therapy to assess healing and rule out Barrett esophagus. Recurrent endoscopy after this follow-up examination is not indicated in the absence of Barrett esophagus.
-History of esophageal stricture who have recurrent symptoms of dysphagia.
-In men older than 50 years with chronic GERD symptoms (symptoms for more than 5 years) and additional risk factors (nocturnal reflux symptoms, hiatal hernia, elevated body mass index, tobacco use, and intra-abdominal distribution of fat) to detect esophageal adenocarcinoma and Barrett esophagus.
-For surveillance evaluation in men and women with a history of Barrett esophagus. In men and women with Barrett esophagus and no dysplasia, surveillance examinations should occur at intervals no more frequently than 3 to 5 years. More frequent intervals are indicated in patients with Barrett esophagus and dysplasia.
The ACP has found evidence that upper endoscopy is indicated in patients with heartburn and alarm symptoms, such as dysphagia, bleeding, anemia, weight loss, and recurrent vomiting. However, upper endoscopy is not an appropriate first step in most patients with GERD symptoms and is indicated only when empirical PPI therapy for 4 to 8 weeks is unsuccessful. Upper endoscopy is not indicated in asymptomatic patients with a history of esophageal stricture but is appropriate in patients with recurrent symptoms of dysphagia.
Screening upper endoscopy should not be routinely done in women of any age or in men younger than 50 years regardless of GERD symptoms because the incidence of cancer is very low in these populations. Screening endoscopy may be indicated in men older than 50 years with several risk factors for Barrett esophagus. This screening decision should include an assessment of the patient's life-limiting comorbid conditions. Risk factors include chronic GERD symptoms (symptoms of >5 years' duration), nocturnal reflux symptoms, hiatal hernia, elevated body mass index, tobacco use, and intra-abdominal distribution of fat. If an initial screening examination is negative for Barrett esophagus or esophageal adenocarcinoma, recurrent periodic endoscopy is not indicated. Among patients found to have Barrett esophagus on screening upper endoscopy, endoscopic surveillance may be indicated at 3- to 5-year intervals. More frequent endoscopic examinations are reserved for patients with low- or high-grade dysplasia because of their higher risk for progression to cancer.
Unnecessary endoscopy exposes patients to preventable harms, may lead to additional unnecessary interventions, and results in unnecessary costs. Patient education strategies should be used to inform patients about current and effective standards of care.
Figure 2 summarizes ACP's best practice advice for the upper endoscopy in the setting of GERD.
