Endoscopic methodEndoscopic featuresSensitivitySpecificityLimitation
Standard endoscopyAntral nodularity32.0%96.0%Low sensitivity
Magnifying endoscopyGastric pits/collecting venules63.9%-93.2%96.2%-100%Lack of uniform diagnostic criteria
NBISECNs95.2%82.2%Low light intensity, and magnification is usually required
I-ScanGastric pits/collecting venules94.0%93.5%Magnification is usually required
NIR Raman endoscopyRaman spectra80.0%100.0%Inconvenient for clinical practice
EndocytoscopyObserve organisms directly--Lack of clinical validation
EndomicroscopyObserve organisms directly/neutrophils infiltration89.2%95.7%Depend upon knowledge of pathology
