Key Takeaway
Utilize lifestyle modification and optimized PPI therapy as first-line treatments for gastroesophageal reflux disease.

This clinical guideline outlines the standardized diagnosis and management of gastroesophageal reflux disease (GERD), nonerosive reflux disease (NERD), and erosive esophagitis specifically within the context of Vietnam. The guidelines aim to provide evidence-based, context-adapted recommendations for clinicians managing these conditions.

The guidelines state that lifestyle modification and optimized proton pump inhibitor (PPI) therapy are the first-line treatments. Potassium-competitive acid blockers may be considered as alternative therapies. For diagnosis, the guideline notes that empiric PPI testing alone is insufficient; instead, upper endoscopy and ambulatory reflux monitoring are recommended for selected patients. High-resolution manometry is advised for those with refractory symptoms or for preintervention evaluation.

Surgical and endoscopic interventions are reserved specifically for patients who demonstrate objective reflux and persistent symptoms despite optimized medical therapy. The guidelines provide a structured framework to standardize care, though specific limitations regarding the evidence base were not reported.

How this fits prior evidence

This guideline addresses a gap in standardized management by providing context-adapted recommendations for GERD in Vietnam. It reinforces the role of proton pump inhibitor (PPI) therapy as a primary treatment and mentions potassium-competitive acid blockers as an alternative. While it does not directly address the 6.9% increase in PPI dose reduction from deprescribing interventions or the risk of laryngeal cancer associated with GERD, it provides a structured framework for managing patients with these conditions.

Living with chronic acid reflux, known as gastroesophageal reflux disease (GERD), can be frustrating and uncomfortable. New clinical guidelines have been established to help doctors in Vietnam provide more consistent care for patients dealing with this condition, including those with nonerosive reflux disease or eroshed esophagitis.

The guidelines emphasize that simply trying a proton pump inhibitor (PPI) medication on its own is not enough to make a full diagnosis. Instead, they recommend using specific tests like upper endoscopies and ambulatory monitoring for certain patients. For those whose symptoms do not improve with standard medicine, specialized tests like high-resolution manometry are advised before considering surgery.

For most people, the first line of defense remains lifestyle changes combined with optimized PPI therapy. While potassium-competitive acid blockers can be used as an alternative, surgical or endoscopic procedures are reserved only for patients who have clear evidence of reflux and persistent symptoms despite trying medical treatments.

What this means for you:
New guidelines prioritize a combination of lifestyle changes and medication before considering surgery for acid reflux.

Common questions

What is the first step in treating acid reflux?

The primary treatment for gastroesophageal reflux disease (GERD) involves a combination of lifestyle modifications and optimized proton pump inhibitor (PPI) therapy. These remain the first-line treatments for patients seeking relief from acid reflux symptoms.

Is taking medication alone enough to diagnose my condition?

No, the guidelines state that testing a proton pump inhibitor (PPI) on its own is not sufficient for a full diagnosis. Doctors may use tools like upper endoscopy or ambulatory reflux monitoring to properly identify the issue.

When is surgery an option for acid reflux?

Surgery and endoscopic interventions are only reserved for patients who have objective reflux and symptoms that persist even after they have tried optimized medical therapy. These options are not the first step for most patients.

Background and AimsGastroesophageal reflux disease (GERD) is common and heterogeneous, with growing recognition of nonerosive reflux disease (NERD) and extraesophageal manifestations in Asia. The variations in diagnostic resources and clinical practice necessitate context-specific, evidence-based guidance. Thus, we developed a guideline that aims to standardize the diagnosis and management of GERD in Vietnam.MethodsA multidisciplinary panel conducted a structured literature search and developed consensus statements using a modified Delphi process. Evidence quality and recommendation strength were evaluated using the GRADE framework.ResultsTwenty recommendations address the diagnostic and therapeutic strategies. Upper endoscopy and ambulatory reflux monitoring are recommended for selected patients, whereas high-resolution manometry is advised for those with refractory symptoms and for preintervention evaluation. Empiric proton pump inhibitor (PPI) testing alone is insufficient for diagnosis. Lifestyle modification and optimized PPI therapy remain the first-line treatments. Standard-duration PPI therapy is recommended for patients with NERD and erosive esophagitis, with optimization required before defining refractory GERD. Potassium-competitive acid blockers may be considered as alternatives. Endoscopic and surgical interventions are reserved for patients with objective reflux and persistent symptoms despite undergoing optimized medical therapy.ConclusionThe developed guideline provides evidence-based, context-adapted recommendations to standardize GERD care in Vietnam.
