Introduction:

Esophageal manometry is the reference test for the diagnosis of esophageal motor disorders; diagnoses known elements in the pathophysiology of gastroesophageal reflux disease, such as hypotony of the lower esophageal sphincter and its transient relaxations. Manometry is used to evaluate peristaltic function in patients considered for anti-reflux surgery, particularly if the diagnosis is uncertain. It should not be used to make or confirm the diagnosis of gastroesophageal reflux disease.

Objective:

To deepen the knowledge related to the motility pattern of gastroesophageal reflux disease in high-resolution manometry.

Development:

High-resolution esophageal manometry allows characterizing the contractile activity of the esophagus. Simultaneously records the activity of the upper and lower esophageal sphincters; also, the motility of the esophageal body. Its indications, although precise, are of interest in certain patients with gastroesophageal reflux disease, especially in those who suspect a motility disorder. The most accepted manometric pattern for gastroesophageal reflux disease describes a failure of the following factors: lower esophageal sphincter pressure, length, instability, the presence of hiatal hernia, and disorders of esophageal peristalsis.

Conclusions:

High-resolution manometry allows us to characterize the motility pattern of gastroesophageal reflux disease. The primary elements of reflux are hypotonia of the lower esophageal sphincter, its transient relaxations, and anatomical distortion of the esophagogastric junction.
