Upper Esophageal Sphincter Resting Pressure Varies during Esophageal Manometry
BACKGROUND The upper esophageal sphincter is composed of striated muscle. The stress of intubation and the need to inhibit dry swallows during an esophageal manometry test may lead to variations in basal pressure of this sphincter. Upper esophageal sphincter is usually only studied at the final part of the test. Was observed during the performance of high resolution manometry that sphincter pre...
متن کاملHow to Perform and Interpret Upper Esophageal Sphincter Manometry
Manometry of the pharynx and the upper esophageal sphincter (UES) provides important information on the swallowing mechanism, especially about details on the pharyngeal contraction and relaxation of the UES. However, UES manometry is challenging because of the radial asymmetry of the sphincter, and upward movement of the UES during swallowing. In addition, the rapidity of contraction of the pha...
متن کاملManometry of the normal upper esophageal sphincter and its alterations in laryngectomy.
Rapid pull-through pressure profiles of the normal human upper esophageal sphincter (UES) were simultaneously studied with a conventional three-orifice Honeywell solid-state probe, an eight lumen radially perfused (RP) probe, and a circumferentially sensitive (CS) probe designed to measure UES pressure (UESP) without regard to probe orientation. Pressure curves were digitized and analyzed by co...
متن کاملThree‐dimensional manometry of the upper esophageal sphincter in swallowing and nonswallowing tasks
OBJECTIVES/HYPOTHESIS High-resolution manometry (HRM) is useful in identifying disordered swallowing patterns and quantifying pharyngeal and upper esophageal sphincter (UES) physiology. HRM is limited by unidirectional sensors and circumferential averaging of pressures, resulting in an imperfect understanding of pressure from asymmetrical pharyngeal anatomy. This study aims to evaluate UES pres...
متن کاملInfluence of head rotation on upper esophageal sphincter pressure evaluated by high-resolution manometry system.
OBJECTIVES This study aimed to quantify the effects of head rotation on upper esophageal sphincter (UES) pressure in healthy subjects using a novel high-resolution manometry (HRM) system. STUDY DESIGN Prospective study. SETTING Nagasaki University Hospital. SUBJECTS AND METHODS Eighteen asymptomatic Japanese male adult volunteers were studied. A solid-state HRM was positioned to record re...
