Recently, there have been some reports that image-enhanced endoscopy (IEE) may be useful for detection of gastric intestinal metaplasia (GIM) (1, 2). Linked color imaging (LCI) enables noninvasive detection of GIM as a lavender color, which is called lavender color sign (LCS) (3). Spraying l-menthol directly onto the gastric antral mucosa is useful for anti-peristalsis. As a secondary effect of spraying l-menthol, Mori et al. reported annular-reticular-like mucosal changes that were mucosal morphologic changes. This article is protected by copyright.
