Clinical Trial: Assessment of Esophageal Motility With Transnasal Endoscopy

Study Status: Completed
Recruit Status: Unknown status
Study Type: Observational

Official Title:

Brief Summary: The purpose of this study is to assese esophageal motor function by simplified transnasal endoscopy compared with esophageal manometry.

Detailed Summary:

Esophageal manometry is a gold standard for diagnosis of esophageal motility disorder. However, esophageal manometry can not detect non-occulsive contraction. Endoscopic evaulation of esophageal motility is difficult becausea swallowing is nearly impossible during endoscopy. Simplified trans nasal endoscopy (E.G. ScanTM, IntroMedic Co.,Ltd.)composed with dysplay system,controller,and disposable probe with compact size.

The esophageal motor function will be assessed with both esophageal manometry and simplifed trnasnasal endoscopy in patients with esophageal motility disorder (such as achalasia) and healthy volunteer. The results of simplifed trnasnasal endoscopy is compared with the results of esophageal manometry.

Current Primary Outcome: Agreement of endoscopic diagnosis of esophageal motor function with manometry [ Time Frame: one day ]

Original Primary Outcome: Same as current

Current Secondary Outcome: Discomfort of simplifed transnasal endoscopy compared with esophageal manomerty estimated by the patietns [ Time Frame: one day ]

Original Secondary Outcome: Same as current
