 There is a maximum point of narrow band imaging magnifying endoscopic diagnosis for superficial esophageal squamous cell carcinoma that contributes to invasion depth. The first basic requirement is to obtain good quality endoscopic images. To achieve this, it is advisable to carefully observe the lesion while changing the quantity of intraesophageal air and positioning of the lesion, as well as the ability to gradually enlarge the magnification is necessary. Next, the typical vessel pattern of the Japan Esophageal Society classification should be well-understood, and attention should be paid to Type B2 microvessel domains in addition to Type B1 microvessels.

 However, there is a problem that Type B2 microvessels show much variation, but we proposed that the correlation between protruding lesions and Type B2 microvessels or their domain characteristics and pT1b-SM2 cancer may be useful. Furthermore, further future research is necessary.
