Narrow-Band Imaging for the Diagnosis of Gastric Preneoplastic and Neoplastic Lesions

AbstractGastric adenocarcinoma is still one of the most common and lethal cancers in the world. Prevention through early diagnosis of premalignant lesions and early gastric cancer could be one of the best strategies for improving survival. Endoscopy is of paramount importance for that purpose. However, endoscopic evaluation of gastric mucosa correlates poorly with histological diagnosis. New methods of electronic chromoendoscopy have emerged as potentially useful for the diagnosis of gastric lesions. The authors have recently shown that a simple high-resolution with narrow-band imaging (NBI) classification is highly accurate and reliable for the diagnosis of gastric preneoplastic and neoplastic lesions. This article shows how to apply this NBI classification for the diagnosis of gastric lesions, using video examples of all the lesions. The authors conclude that this new NBI classification can easily be applied in routine clinical practice with high accuracy. This article is part of an expert video encyclopedia
