High-Resolution Manometry Studies Are Frequently Imperfect but Usually Still Interpretable

High resolution manometry – an introduction

Recent Concept in Interpreting High-Resolution Manometry

Esophageal manometry is considered the gold standard for assessing esophageal motor function. Although conventional manometry has been widely used to evaluate esophageal motor function, this is not fully satisfactory for explaining esophageal symptoms. High-resolution manometry (HRM) is designed to overcome the limitations of conventional manometric systems with advanced technologies. A solid-s...

Event Prediction in Pharyngeal High-Resolution Manometry

A prolonged phase of increased pressure in the upper esophageal sphincter (UES) after swallowing might result in globus sensation. Therefore, it is important to evaluate restitution times of the UES in order to distinguish physiologic from impaired swallow associated activities. Estimating the event t where the UES has returned to its resting pressure after swallowing can be accomplished by pre...

High-Resolution Manometry in Clinical Practice.

High-resolution manometry (HRM) is the primary method used to evaluate esophageal motor function. Displayed and interpreted by esophageal pressure topography (EPT), HRM/ EPT provides a detailed assessment of esophageal function that is useful in the evaluation of patients with nonobstructive dysphagia and before foregut surgery. Esophageal motility diagnoses are determined systematically by app...

High-resolution Manometry and Globus: Comparison of Globus, Gastroesophageal Reflux Disease and Normal Controls Using High-resolution Manometry

BACKGROUND/AIMS Globus is a foreign body sense in the throat without dysphagia, odynophagia, esophageal motility disorders, or gastroesophageal reflux. The etiology is unclear. Previous studies suggested that increased upper esophageal sphincter pressure, gastroesophageal reflux and hypertonicity of esophageal body were possible etiologies. This study was to quantify the upper esophageal sphinc...
