[NBI magnifying endoscopic classification using crystal violet staining].
NBI magnifying imaging with crystal violet (CV-NBI magnifying imaging) makes recognition of micro-vascular pattern and grandular structure in the gastric mucosa better. NBI image emphasizes micro-vascular structure in mucosal surface. Magnification endoscopy with crystal violet staining delineates surface grandular structure better than without it. Crystal violet stained epithelium is clearly observed as cobalt green with NBI imaging. In the classification of CV-NBI magnification findings, 71% of differentiated type lesion was classified into ILL (intralobular loop pattern), and the rest (29%) was diagnosed as FNP (fine network pattern) which was originally advocated by Nakayoshi, et al. ILL is the new category of magnifying endoscopy. ILL corresponded mainly to differentiated-type adenocarcinoma, but it also includes undifferentiated-type adenocarcinoma. Corkscrew pattern is corresponding well to undifferentiated-type adnocarcinoma (Nakayoshi, et al). CV-NBI magnifying classification is considered to be related to tissue characterization in gastric cancer.
