Magnifying narrow-band imaging endoscopy is superior in diagnosis of early gastric cancer

Figure 1 Assessment of the margin between the lesion and the surrounding mucosa was made and recorded as present or absent. A: High definition white light endoscopy finding of a focal lesion 15 mm x 10 mm in diameter, IIa + IIc type in the gastric antrum; B: Magnifying endoscopy shows irregular pattern of microsurface, with a relatively clear demarcation line; C: Magnifying narrow-band imaging endoscopy shows irregular and absent microsurface pattern, and microvascular dilation, with a clear demarcation line. The histopathological diagnosis of the surgery specimen is early gastric cancer (revised Vienna classification C5).
