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.

fluence. Portal vein aneurysms are either congenital or acquired. Most acquired portal vein aneurysms occur as a consequence of portal hypertension. In this case, the etiology was likely congenital, although malignant invasion of the portal vein could not be excluded. Although rare, complications may occur, including thrombosis, biliary obstruction, inferior vena cava obstruction, duodenal compression, and rupture. In asymptomatic patients, aneurysms can be monitored for expansion by serial CT scans. In symptomatic patients or if the aneurysm is expanding, surgical decompression can be done, either by shunt or aneurysm repair. 2

With a cut-off number of visualized CO of 20, the sensitivity, specificity and accuracy of dense-type CO for discriminating between LGA and EGC were 90.0%, 87.8% and 88.2%, respectively.…”

Evaluating the prevalence and severity of gastritis by endoscopy is useful for estimating the risk of gastric cancer (GC). Moreover, understanding the endoscopic appearances of gastritis is important for diagnosing GC due to the fact that superficial mucosal lesions mimicing gastritis (gastritis-like lesions) are quite difficult to be detected even with optimum preparation and the best technique, and in such cases tissue biopsy is often not very accurate for the diagnosis of gastric epithelial neoplasia. Magnifying endoscopy is a highly accurate technique for the detection of early gastric cancer (EGC). Recent reports have described that various novel endoscopic markers which, visualized by magnifying endoscopy with image-enhanced system (ME-IEE), can predict specific histopathological findings. Using ME-IEE with vessels and surface classification system (VSCS) may represent an excellent diagnostic performance with high confidence and good reproducibility to the endoscopists if performed under consistent conditions, including observation under maximal magnification. The aim of this review was to discuss how to identify high-risk groups for GC by endoscopy, and how to detect effectively signs of suspicious lesions by conventional white light imaging (C-WLI) or chromoendoscopy (CE). Furthermore, to characterize suspicious lesions using ME-IEE using the criteria and classification of EGC based upon VSCS.
