American Society for Gastrointestinal Endoscopy guideline on the diagnosis and management of GERD: summary and recommendations.

This clinical practice guideline from the American Society for Gastrointestinal Endoscopy (ASGE) provides an evidence-based approach for strategies to diagnose and manage GERD. This document was developed using the Grading of Recommendations Assessment, Development, and Evaluation framework and serves as an update to the 2014 ASGE guideline on the role of endoscopy in the management of GERD. This updated guideline addresses the indications for endoscopy in patients with GERD as well as in the emerging population of patients who develop GERD after sleeve gastrectomy or peroral endoscopic myotomy. It also discusses how to endoscopically evaluate gastroesophageal junctional integrity in a comprehensive and uniform manner. Importantly, this guideline also discusses management strategies for GERD including the role of lifestyle interventions, proton pump inhibitors (PPIs), and endoscopic antireflux therapy (including transoral incisionless fundoplication [TIF], radiofrequency energy, and combined hiatal hernia repair and TIF [cTIF]) in the management of GERD. The ASGE suggests upper endoscopy for the evaluation of GERD in patients with alarm symptoms, with multiple risk factors for Barrett's esophagus, and with a history of sleeve gastrectomy. The ASGE recommends careful endoscopic evaluation, reporting, and photo-documentation of objective GERD findings with attention to gastroesophageal junction landmarks and integrity in patients who undergo upper endoscopy to improve care. In patients with GERD symptoms, the ASGE recommends lifestyle modifications. In patients with symptomatic and confirmed GERD with predominant heartburn symptoms, the ASGE recommends medical management including PPIs at the lowest dose for the shortest duration possible while initiating discussion about long-term management options. In patients with confirmed GERD with small hiatal hernias (≤2 cm) and Hill grade I or II who meet specific criteria, the ASGE suggests evaluation for TIF as an alternative to chronic medical management. In patients with persistent GERD with large hiatal hernias (> 2cm) and Hill grade III or IV, the ASGE suggests either cTIF or surgical therapy based on multidisciplinary review. This document summarizes the methods, analyses, and decision processes used to reach the final recommendations and represents the official ASGE recommendations on the above topics.
