Emergent endoscopy is needed in cases of a fish bone foreign body in the upper gastrointestinal tract. A fish bone foreign body is common in the oral cavity and pharynx and has a high rate of complications because of the characteristic shape. A diagnosis is very difficult when the foreign body penetrates and impacts the surrounding tissue. Computed tomography is useful for the diagnosis; however, direct removal would be impossible if the foreign body was not localized during endoscopy. If the foreign body is anchored to the oral cavity and pharynx, finger palpation is useful to find the impacted fish bone. We report here on a case of an endoscopically missed pharyngeal impacted fish bone foreign body that was finally detected by finger palpation and successfully removed by rescue endoscopy.
