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 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...
متن کاملUpper esophageal sphincter during transient lower esophageal sphincter relaxation: effects of reflux content and posture.
Although some studies show that the upper esophageal sphincter (UES) contracts during transient lower esophageal sphincter relaxation (TLESR), others show that it relaxes. We hypothesized that the posture of the subject and constituents of gastroesophageal reflux (GER) may determine the type of UES response during the TLESR. High-resolution manometry and esophageal pH/impedance recording were p...
متن کاملUpper esophageal sphincter function during gastroesophageal reflux events revisited.
Upper esophageal sphincter (UES) function during gastroesophageal reflux events is not completely elucidated because previous studies addressing this issue yielded conflicting results. We reexamined the UES pressure response to intraluminal esophageal pressure and pH changes induced by reflux events. We studied 14 healthy, asymptomatic volunteers (age 49 +/- 6 yr) and 7 gastroesophageal reflux ...
