| Outline of Final Research Achievements |
We developed a new balloon type manometry and detected its measurement accuracy and safety. The measurement accuracy between the high-resolution manometry and this new balloon type manometry was extremly precise(R2=0.97). The balloon was not broken by less than 1kgf pulling force. The pulling force of balloon catheter during hard swallowing at vallecular was measured by a tension meter, and it indicated 3.6Ｎ.
Intra-balloon pressure of five healthy subjects at vallecula during hard swallowing were higher than that during air swallowing. Seven dysphagics expressed lower intra-balloon pressure at vallecula during both air and hard swallowing according to dysphagia severity scale. This new balloon type manometry is clinically useful and safety to detect swallowing pressure at vallecula.
