Intra-esophageal pressure was measured in patients with unusual sensation of the pharynx and larynx. The results were compaired with those in normal subjects and the interest was on analysis of the cause of this ailment.
The characteristics of the results were summerized and described as follows:
1) Cessation of peristalsis in the patients was observed more frequently than in normal subjects.
2) Some showed a general slowing of peristalsis and some showed a fast peristalsis in the lower esophagus.
3) Tow- or Three- peaked waves were observed in many cases, and a wave suggestive of non-peristaltic wave was also observed.
4) The above mentioned findings were compatible with x-ray findings in the patients with unusual sensation of the pharynx and larynx.
