ARMS (Anti-Reflux Mucosectomy) is an advanced, minimally invasive endoscopic procedure used for the treatment of gastroesophageal reflux disease (GERD), especially in patients who have persistent symptoms despite medical therapy or wish to avoid long-term medication or surgery. The procedure works by enhancing the natural anti-reflux barrier at the gastroesophageal junction.

During ARMS, a controlled mucosal resection is performed endoscopically at the junction of the esophagus and stomach. Healing of this resected area leads to fibrosis and tightening of the gastroesophageal junction, which helps prevent the backflow of stomach acid into the esophagus. The procedure is performed through the mouth using a flexible endoscope, without any external incisions.

ARMS is particularly suitable for patients with mild to moderate GERD, those with small or no hiatal hernia, and patients who continue to have reflux symptoms despite optimal medical treatment. It may also be considered in selected patients who are not ideal candidates for anti-reflux surgery or prefer an endoscopic solution.

The advantages of ARMS include minimal invasiveness, shorter procedure time, reduced hospital stay, and faster recovery compared to surgical options. Many patients experience significant improvement in heartburn, regurgitation, and overall quality of life, along with reduced dependence on long-term acid-suppressing medications.

With growing clinical experience and favorable outcomes, ARMS has emerged as a safe and effective endoscopic therapy for GERD. When performed by skilled endoscopists, it offers durable symptom relief while preserving normal anatomy, making it a valuable option in modern reflux management.
