Methods for Measuring Swallowing Pressure Variability Using High-Resolution Manometry

Investigation of pharyngeal swallowing function using high-resolution manometry.

OBJECTIVES/HYPOTHESIS This study aimed to demonstrate the feasibility of a novel high-resolution manometry system, and to establish normal values of swallowing pressures along the velopharynx and upper esophagus. STUDY DESIGN Prospective study. METHODS Thirty-three asymptomatic adult Japanese controls were studied. A solid-state high-resolution manometry assembly with 36 circumferential sen...

Quantitative Analysis of Swallowing Function Between Dysphagia Patients and Healthy Subjects Using High-Resolution Manometry

Objective To compare swallowing function between healthy subjects and patients with pharyngeal dysphagia using high resolution manometry (HRM) and to evaluate the usefulness of HRM for detecting pharyngeal dysphagia. Methods Seventy-five patients with dysphagia and 28 healthy subjects were included in this study. Diagnosis of dysphagia was confirmed by a videofluoroscopy. HRM was performed to...

High resolution manometry – an introduction

The effect of bolus consistency on swallowing function measured by high-resolution manometry in healthy volunteers.

OBJECTIVES/HYPOTHESIS This study evaluated the effects of three levels of bolus consistency (water, thick liquid, and paste) on the nature and duration of physiologic pressure while swallowing in healthy adults using high-resolution manometry (HRM). STUDY DESIGN A case series of healthy adults. METHODS Thirty-four healthy young adults (mean age: 24.29 years) were instructed to swallow 3 mL ...

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...
