Abstract

Heterotopic gastric gland (HGG)-originating early gastric cancer was endoscopically resected. We resected the HGG, widely marked the perimeter outside the submucosal tumor-like area, injected from outside the markings into the submucosa, dissected the muscular layer, and used fine-tip hood. HGG removal and ensuring negative horizontal and vertical margins are critical.
