Brief summary
This is a pilot study of a novel disposable transnasal esophagoscope for feasibility, safety and tolerance.
Detailed description
A disposable, transnasal esophagoscope, E.G. ScanTM was developed by IntroMedic Co. Ltd. (Seoul, Korea). This device was designed to allow patient to undergo endoscopy with minimum pain without sedation. This endoscopy system consists of thin probe with a CMOS camera, controller and simple display system. This system is light enough to carry and does occupy much space, and thus, it can be used at patient bed sides in intensive care units, in emergency rooms, and even in doctor's offices.
