To evaluate the rate of identifying the distal end of the palisade vessels (DEPV) and discrepancy between DEPV and proximal end of the gastric folds (PEGF) in EGD under sedation, and to establish the method for identifying GOJ
Efficacy
The rate of identifying DEPV in white light imaging
1) Difference of the rates of identifying DEPV among each sedation type
2) Difference of the rates of identifying DEPV between patients with and without hiatal hernia
3) Difference of the rates of identifying DEPV in patients with and without reflux esophagitis (Los Angeles classification N, M, A, B, C, and D)
4) Difference of the rates of identifying DEPV between patients with and without Helicobacter pylori infection and among degree of endoscopic gastric atrophy
5) Difference of the rates of identifying DEPV among white light imaging and various type of image enhanced endoscopy (NBI, BLI, LCI, TXI, and RDI)
6) Difference of the rates of identifying DEPV between transoral and transnasal endoscopy and among various type of endoscope
7) The length of palisade vessels which can be seen underneath the columnar epithelium
8) Concordance rate between DEPV and PEGV (and condition of the concordance)
9) Intraobserver and interobserver agreement for visibility of DEPV
10) Factors associated with no identification of DEPV
