Influence of effortful swallow on pharyngeal pressure: evaluation using a high-resolution manometry.
OBJECTIVE To evaluate the effect of effortful swallow on pharyngeal pressure while swallowing saliva and water using a novel high-resolution manometry (HRM) system. STUDY DESIGN Case series with planned data collection. SETTING Nagasaki University Hospital. SUBJECTS AND METHODS Eighteen asymptomatic Japanese adult volunteers were studied. A solid-state HRM assembly with 36 circumferential...
متن کاملMultiple Rapid Swallow Maneuver Enhances the Clinical Utility of High-Resolution Manometry in Patients Showing Ineffective Esophageal Motility
The clinical significance of ineffective esophageal motility (IEM) together with multiple rapid swallow (MRS) has not been yet evaluated in the Chicago Classification v3.0. This study evaluated the adjunctive role of MRS in IEM and determined the criteria of abnormal MRS to maximize the utility of IEM. We analyzed 186 patients showing IEM or normal esophageal motility (NEM), who underwent esoph...
متن کاملMagnetic resonance imaging of the effortful swallow.
OBJECTIVE The effortful swallow was designed to improve posterior mobility of the tongue base and increase intraoral pressures. We characterized the effects of this maneuver via dynamic magnetic resonance imaging (dMRI) in healthy patients. METHODS A 3-T scanner was used to obtain dMRI images of patients swallowing pudding using normal as well as effortful swallows. Ninety sequential images w...
متن کاملTiming of Pharyngeal Swallow Events in Chagas’ Disease
BACKGROUND Esophageal involvement by Chagas' disease causes a significative decrease in the number of neurons of the esophageal myenteric plexus, causing an impairment of esophageal motility with the same alterations described in primary esophageal achalasia. There is also a longer duration of pharyngeal transit, which might be consequent of the involvement of the central control of swallowing ...
متن کاملEffects of Head Rotation and Head Tilt on Pharyngeal Pressure Events Using High Resolution Manometry
OBJECTIVE To observe changes in pharyngeal pressure during the swallowing process according to postures in normal individuals using high-resolution manometry (HRM). METHODS Ten healthy volunteers drank 5 mL of water twice while sitting in a neutral posture. Thereafter, they drank the same amount of water twice in the head rotation and head tilting postures. The pressure and time during the de...
