Core Tip

Core Tip: Narrow-band imaging has enabled the analysis of gastrointestinal mucosa in microscopic detail. However, this technique gives a dark image and makes it impossible to identify the color and structural microanatomy changes of the stomach mucosa, and it is necessary to combine it with the mechanical addition on the top of the scope (conventional magnification). These additions improve the visualization of the gastric mucosa but significantly complicate the procedure. We presented a new endoscopic mode called “near focus” that achieves the same or better visualization and does not require any additional accessories.
