Removal of an embedded gastric fishbone by traction-assisted endoscopic full-thickness resection

A 65-year-old man was referred to our hospital with a half-year history of upper abdominal pain. Endoscopy showed a submucosal eminence on the anterior wall of the gastric antrum ([Fig. 1] a). Endoscopic ultrasonography (EUS) revealed a hyperechoic lesion in the gastric submucosa ([Fig. 2]). A computed tomography (CT) scan showed a long, high density shadow in the gastric antrum, locally protruding into the serosal cavity ([Fig. 3]). Emergency endoscopy was performed with the patient under general anesthesia and with endotracheal intubation ([Video 1]).
