Assessment of Esophageal Motility With Transnasal Endoscopy
Recruitment status was Recruiting
The purpose of this study is to assese esophageal motor function by simplified transnasal endoscopy compared with esophageal manometry.
Esophageal Motility Disorder
|Study Design:||Observational Model: Case-Only
Time Perspective: Prospective
- Agreement of endoscopic diagnosis of esophageal motor function with manometry [ Time Frame: one day ] [ Designated as safety issue: No ]
- Discomfort of simplifed transnasal endoscopy compared with esophageal manomerty estimated by the patietns [ Time Frame: one day ] [ Designated as safety issue: No ]
|Study Start Date:||July 2011|
|Estimated Study Completion Date:||October 2012|
|Estimated Primary Completion Date:||September 2012 (Final data collection date for primary outcome measure)|
Healthy volunteers and patients with esophageal motor symptom will be enrolled and esophageal motility assessed by transnasal endoscopy according to clinical and manometric diagnosis
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.
