 The aim of this study was to evaluate the correlation between B3 pattern vessels of the magnifying endoscopic classification of the Japan Esophageal Society and T1b-SM2/SM3 invasion. We retrospectively evaluated 464 esophageal carcinoma lesions that were endoscopically or surgically resected in our hospital from July 2001 to June 2013. Sensitivity, specificity, PPV(positive predictive value), negative predictive value, and accuracy of B3 pattern vessel for diagnosis were 56.9%, 99.5%, 95.3%, 92.6%, and 92.6%, respectively. Lesions that had B3 pattern vessels were highly likely to be T1b-SM2/SM3 lesions. However, the frequency of the lesions that were negative for B3 pattern vessels was 43.1%. Therefore, it is necessary to provide evidence of the diagnostic strategy for such lesions that have mainly B2 pattern vessels.
