A Case of Symptomatic Diffuse Esophageal Spasm During Multiple Rapid Swallowing Test on High-Resolution Manometry

Diffuse esophageal spasm (DES) is an uncommon motility disorder of unknown etiology in which the abnormal motility has been offered as a possible cause for the patient's dysphagia or chest pain. Esophageal manometry is the gold standard for the diagnosis of DES and the diagnostic hallmark is identification of simultaneous contractions in at least 20% of wet swallows, alternating with normal per...

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...

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...

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...
