 In order to improve the accuracy of endoscopic diagnosis of early gastric cancer, it is essential to verify the preoperative diagnosis by comparing endoscopic and histopathological results. Remarkable recent advances in endoscopic devices, including magnifying endoscopy with narrow-band imaging, have enabled a more detailed endoscopic diagnosis. Therefore, it is necessary to effectively compare histopathological and magnifying endoscopy results. First, we detected the area of interest through a detailed endoscopic observation and subsequently marked an area in its proximity. Furthermore, we acquired an endoscopic image of both the marked area and the area of interest. Finally, we resected the specimen to evaluate the area of interest using the marked area as an indicator.
