The pathophysiology and treatment of gastroesophageal reflux disease: new concepts

Abstract

In summary, the recent understanding of the pathogenesis of gastroesophageal reflux disease as owing to LES incompetence has led to improvement in both the diagnosis and the treatment of this disorder. Diagnosis now dependent on demonstrating the presence of reflux, an incompetent sphincter mechanism, or some complication of reflux. Treatment is focused on reducing the endogenous factors that contribute to reflux, or actually restoring the sphincteral barrier to reflux by pharmacologic or surgical means.
