Official Title: The Role of Endoscopic Tri-Modal Imaging in Distinguishing Functional Dyspepsia From Reflux Disease
Brief Summary: Endoscopic Tri-Modal Imaging which combines Narrow-band Imaging(NBI), Autofluorescence Imaging (AFI) and White-light Imaging (WLI) could be used to identify the indistinct changes in the gut caused by reflux disease,either acid reflux or bile reflux, which make it possible to differentiate reflux disease from functional dyspepsia (FD).
