Endoscopic Submucosal Dissection for Exploration and Removal of a Gastric Buried Foreign Body

Foreign body (FB) fully embedded in the gastrointestinal tissue forming a buried FB is rare, characterized by deceiving endoscopic appearances, e.g., erosion, ulceration, or subepithelial lesion. Conventional endoscopic removal is challenging in this circumstance under which surgery is usually indicated. We reported a gastric buried FB that treated via endoscopic submucosal dissection.
