Endoscopic removal of gastric ectopic pancreas: An initial experience with endoscopic submucosal dissection

Figure 1 Endoscopic mucosal resection of ectopic pancreas by injection-and-cut technique (case 3). A: A subepithelial lesion is observed on the greater curvature of the antrum; B: Endoscopic ultrasonography image obtained with a 20 MHz catheter probe. An indistinct, heterogeneous, and hypoechoic lesion with a small anechoic space is located within the submucosal layer; C: Saline with indigo carmine is injected into the submucosa beneath the lesion; D: The lesion is resected using an electrocautery snare; E: The lesion is completely removed; F: The inner surface of the resected specimen; G: Histologically, the ectopic pancreas is located in the submucosa (HE, × 40).
