“…10,36,62 In cases in which the WOS is observed, rather than assessing the MVP, morphological analysis of the WOS could be an alternative marker of MS pattern. 10,36,62 as demonstrated in Figures 11,13,17. In the regular MS pattern (Figs 13, 15), the MCE/WZ is a uniform linear, curved, oval, or circular structure with homogeneous morphology, symmetrical distribution, and regular arrangement. In the irregular MS pattern (Figs 13, 16), the MCE/WZ is an irregular linear, curved, oval, circular, or villous structure with heterogeneous morphology, asymmetrical distribution, and The microvasculature (subepithelial capillary network) of the lesion is gradually dilated from the background mucosa.…”

The Japanese Gastroenterological Association, 2 Japan Gastroenterological Endoscopy Society, Tokyo, and 3 The Japanese Gastric Cancer Association, Kyoto, JapanGastric cancer is the third leading cause of cancer death worldwide. Early detection and accurate diagnosis of mucosal cancer is desirable in order to achieve decreased mortality; cause-specific survival of patients with early gastric cancer is reported to exceed 95%. Endoscopy is the functional modality to detect early cancer; however, the procedure is not definitive when using conventional white-light imaging. In contrast, magnifying narrow-band imaging (M-NBI), a novel endoscopic technology, is a powerful tool for characterizing gastric mucosal lesions because it can visualize the microvascular architecture and microsurface structure. To date, many reports on the diagnosis of early gastric cancer by M-NBI, including multicenter prospective randomized studies conducted in Japan, have been published in peer-reviewed international journals. Based on these published data, we devised a proposal for a diagnostic strategy for gastric mucosal cancer using M-NBI to simplify the process of diagnosis and improve accuracy. Herein, we recommend a diagnostic algorithm for early gastric cancer using magnifying endoscopy.

“…On the other hand, a destroyed pit pattern on magnifying endoscopy has a sensitivity and specificity both reaching 100% in predicting tumor lesions. Besides, Kosaka et al [42] reported the efficacy of several modalities in identifying and demarcating residual or local recurrent gastric neoplasm after ER, including conventional ME, enhanced-ME with acetic acid instillation (EME), ME-NBI, and NBI-EME. It turned out that a combination of NBI or acetic acid instillation was very effective in ME for post-ER followup.…”

Narrow band imaging (NBI), in conjunction with magnifying endoscopy (ME), has arisen more and more attention in the area of advanced endoscopy. By enhancing the mucosal microvascular architecture and surface pattern, it is feasible to use ME-NBI to identify subtle changes associated with gastric inflammation, atrophy, intestinal metaplasia, and early gastric cancer. The new technique thus plays a valuable role in therapeutic decision-making, endoscopic treatment process, postoperative evaluation, and follow-up examination. To date, many criteria or evaluation method of ME-NBI has been proposed. This paper aims to summarize the various diagnosing classifications and the current clinical applications of ME-NBI in the stomach.

Narrow band imaging: Application for early‐stage gastrointestinal neoplasia

Narrow-band imaging (NBI) is an imaging technique for endoscopy using optical filters to narrow the bandwidth of spectral transmittance. Through this narrow spectrum, NBI contrasts surface structure and microvascular architecture of various lesions. In this article we focus on the application of NBI for early-stage neoplasia in the esophagus, stomach and colon with a three-step strategy of endoscopic diagnosis: (i) the detection of abnormality; (ii) the differentiation between non-neoplasia and neoplasia; and (iii) staging for tumor extension and depth of invasion.
