If a patient accidentally eats a fish spike, it is recommended that the patient immediately prohibits water and does not use buns or rice balls to swallow hard, which not only does not get out the fish spike, but makes it stick deeper. Patients should not drink vinegar and other native methods, which will not help to remove the fish spike either. The patient should go to an ENT clinic as soon as possible, where the doctor will look at the oropharynx with a tongue depressor and then at the bottom of the throat with an indirect laryngoscope to see if there is a fish spike, and if there is one, it can be removed directly with a foreign body clamp. If no fish spike is found through these two examinations, but the patient feels uncomfortable, it is recommended to have an electronic laryngoscopy, which can be magnified many times and can clearly see small fish spikes, as well as those in more hidden places, and if found, can be removed directly under the guidance of the electronic laryngoscope. In rare cases, the fish spike is stuck in the esophagus, which requires an electrogastroscopy or a CT examination of the esophagus.
