 Purpose : The effectiveness of and problems related to using magnification endoscopy combined with narrow-band imaging laparoscopy(M-NBI)in the differential diagnosis adenoma and carcinoma, in a case of surface-grown type epithelial carcinoma were studied.

 Subjects and methods : The 147 lesions of surface-grown type epithelial carcinoma[light to medium degree atypical tumor(LGA)group, 48 lesions ; gastric cancer and high degree atypical tumor(EC)group, 99 lesions]were included in the study. Skilled and unskilled practitioners determined the diagnostic performance of common-white light imaging(C-WLI)and M-NBI for comparison.

 Results : The diagnostic performance score determined by both, the skilled and unskilled practitioners, was high in sensitivity for M-NBI using the VS classification system(VSCS), as compared with that for C-WLI. However, the unskilled practitioners determined low specificity for M-NBI(84.8% vs 70.8%), particularly in the low certainty factor group. The score for specificity was as low as 37.5%, which was lower than that for C-WLI. On adding VS discordance, vessels within epithelial circle pattern(VEC pattern), and dense-type crypt opening(dense-CO)to the M-NBI low certainty factor group, we observed that the practitioners' score of specificity improved.

 Conclusion : M-NBI using the VSCS is effective for skilled as well as unskilled practitioner in the differential diagnosis of adenoma and carcinoma, as compared with that by C-WLI. In addition, VS discordance, VEC pattern and dense-CO were effective for unskilled practitioners to improve their specificity score.
