No results posted yet for this study

Summary

Understanding the correlation between the transmission of a bolus from the pharynx into the proximal esophagus and activating primary esophageal peristalsis.

Conditions

  • Deglutition Disorders

Interventions

PROCEDURE

pharyngo-esophageal high-resolution manometry

The high resolution manometry (HRM) catheter will be inserted through the more patent nares and positioned such that it covers the pharynx and the esophagus. Affixed to the high resolution catheter will be a single lumen, end-hole catheter (length: 90 cm, outside diameter: 1.58 mm) wherein the end hole of the tube will be secured at a fixed pharyngeal site on the HRM catheter and the other end of the tube will be connected to a stopcock so that the tube may be either open or closed to atmospheric pressure. 3. Study subjects will be asked to swallow their ambient saliva ten times with the stopcock open and ten times with the stopcock closed. There is a 30 second interval between swallows.
