Core Tip

Core tip: It is rare to find the fish bone completely embedded in the wall of the esophagus with endoscopic findings similar to those of submucosal tumors. We report a fish bone that is fully embedded and migrated through the esophageal wall. During the operation, it was found that the fish bone was not directly below the highest point of the mass protuberance. Therefore, it is suggested that submucous injection of methylene blue under endoscopic ultrasonographic guidance can be used to locate the foreign body accurately and reduce the injury of treatment.
