About

The ARMA technique improves GORD-related quality of life with a low proportion of adverse effects.

Full description

Gastroesophageal reflux disease (GERD) is defined as the presence of symptoms or complications secondary to the passage of gastric contents into the esophagus, oral cavity or structures of the airway. The prevalence worldwide is between 8-33%. The clinical practice guidelines of the American College of Gastroenterology establish that first-line treatment, in the absence of alarm symptoms, should be carried out empirically. This treatment consists of hygienic-dietary measures and the use of proton pump inhibitors (PPIs) for 8-12 weeks. Despite the proven effectiveness of PPIs, there is 10-40% of patients who do not respond adequately to this treatment. All this has motivated the appearance of endoscopic and surgical techniques that offer an alternative to medical treatment. Among them is the technique of antireflux ablation of the cardiac mucosa (ARMA) in which the resection of the mucosa is replaced by an ablation with electrocoagulation current or by argon gas fulguration.
