“…Although several previous studies have reported a correlation between the endoscopic fine mucosal pattern seen in the gastric mucosa with magnifying endoscopy and histopathology [7,8,9,10,11], reports investigating correlation between magnifying NBI appearances and pathology in non-neoplastic gastric mucosa have been relatively rare. …”

Combining the narrow-band imaging (NBI) system and magnifying endoscopy allows simple and clear visualization of microscopic structures of the superficial mucosa and its capillary patterns, which may be useful for precise endoscopic diagnosis in the gastrointestinal tract, being more closely to histopathological diagnosis. In the non-neoplastic gastric mucosa, there have been reports showing a potential usefulness of magnifying NBI for the diagnosis of Helicobacter pylori infection, degree of histological gastritis, and intestinal metaplasia. We have shown that magnifying NBI appearances in the non-neoplastic gastric mucosa also predicts pepsinogen levels, which indicates extension of gastric atrophy in the entire stomach, and gastric cancer occurrence. Furthermore, we have shown that magnifying NBI appearances predicts the result of H. pylori treatment. Clear visualization of fine mucosal and capillary patterns, obtained by magnifying NBI, allows prediction of the histological condition, more in detail without biopsy, and it may also be useful for less invasive, and cost-effective endoscopic gastric cancer surveillance, and prediction of H. pylori eradication.

“…Therefore, it is often found that the definitive diagnosis of MALT lymphoma can not be obtained after multiple biopsies even in cases where gastric MALT lymphoma is suspected based on endoscopic features of conventional endoscopy. The usefulness of magnified endoscopy (ME) combined with narrow band imaging (NBI) is well recognized in the diagnosis of gastritis and gastric cancer [6][7][8][9] . Recently, the characteristic features of gastric MALT lymphoma, based on magnified endoscopic imaging without NBI, were reported by Ono et al [10] .…”

Usefulness of Magnifying Narrow-Band Imaging Endoscopy for the Diagnosis of Gastric and Colorectal Lesions

A series of studies about the potential usefulness of magnifying endoscopy with narrow-band imaging (NBI) for the diagnosis of gastric and colonic lesion is reviewed. Concerning the magnifying NBI appearances of gastric lesions, a light blue crest is a highly accurate sign of the presence of histological intestinal metaplasia. Also, the degree of irregularity of the mucosal and vascular pattern is correlated with the histological severity of Helicobacter pylori-associated chronic gastritis. According to the ‘VS classification’, an irregular microvascular pattern and/or an irregular microsurface pattern together with a clear demarcation line are characteristic for early gastric carcinoma, and a multicenter prospective randomized controlled trial demonstrated that magnifying endoscopy with NBI is superior to ordinary white light endoscopy for making a differential diagnosis of a small depressed lesion between carcinoma and non-carcinoma. Concerning the magnifying NBI appearances of colonic tumor, the vague or invisible microvascular pattern is mostly observed in hyperplastic polyp. The regular meshed microvascular pattern is mostly observed in adenoma. The irregular meshed microvascular pattern is mostly observed in intramucosal or shallow submucosal-invasive carcinoma. The decreased or loose microvasucular pattern is mostly observed in deep submucosal-invasive carcinoma. Thus, magnifying NBI endoscopy is useful for the differentiation of colorectal non-adenomatous lesions from adenoma, the differentiation of adenoma from carcinoma, and the assessment of invasion depth of early colorectal carcinoma. At present, several magnifying NBI classifications for the diagnosis of early colorectal neoplasia have been proposed in Japan. Recently, the NICE classification based on NBI findings with/without magnification for colorectal tumor was established by an international group.
