 Type-B3 vessel is a diagnostic criterion for cT1b-SM2 tumors in a magnifying endoscopic classification of the Japan Esophageal Society. The sensitivity of B3 vessels for pT1b-SM2 tumors was 25% based on the analysis conducted at our hospital. Although B3 vessels demonstrated pT1b-SM2 tumors, B3 vessels in SMT-like marginal elevation did not always correspond to pT1b-SM2 tumors. The diameter of B2 vessels can reach more than 10mm, and B2 vessels on 0-I protrusion can be considered as criterion for cT1b-SM2 tumors to supplement the low sensitivity of B3 vessels for pT1b-SM2 tumors. Although these criteria increase the sensitivity of diagnosis of cT1b-SM2 tumors, the sensitivity and specificity of cT1b-SM2 tumors diagnosis should be reviewed prospectively. EUS provides additional information along with conventional endoscopy and magnified endoscopy in the prediction of tumor invasion depth, especially in elevated esophageal cancers.
