ARMA (Anti-Reflux Mucosal Ablation) is a minimally invasive endoscopic treatment designed to manage gastroesophageal reflux disease (GERD) by strengthening the natural anti-reflux barrier at the gastroesophageal junction. It is an effective option for patients who continue to experience reflux symptoms despite optimal medical therapy and wish to avoid long-term medication or surgical intervention.

In ARMA, controlled thermal ablation of the mucosa is performed endoscopically at the gastroesophageal junction using techniques such as argon plasma coagulation or radiofrequency energy. As the treated area heals, it undergoes fibrosis and tightening, which enhances the competency of the lower esophageal sphincter and reduces acid reflux. The procedure is performed through the mouth without any external incisions.

ARMA is best suited for patients with mild to moderate GERD, particularly those with minimal or no hiatal hernia. It can also be considered in selected post-endoscopic or post-surgical patients with recurrent reflux symptoms. Careful patient selection ensures optimal outcomes and sustained symptom relief.

The benefits of ARMA include its minimally invasive nature, shorter procedure time, minimal discomfort, and quick recovery. Most patients can return to daily activities within a short period and experience a significant reduction in heartburn, regurgitation, and reliance on acid-suppressing medications.

With encouraging clinical results, ARMA has emerged as a safe and effective endoscopic option for GERD management. When performed by experienced endoscopists, it offers durable symptom control while preserving normal anatomy and improving overall quality of life.
