If the fishbone cannot be found by laryngoscopy, gastroscopy and CT of the larynx and esophagus are needed to determine the location of the fishbone according to the results of the gastroscopy and CT, and to determine whether surgery is needed. 1. No need for surgery: If the fishbone is not found by gastroscopy and CT of the larynx and esophagus, surgery may not be needed. This may be because the fishbone has fallen out and the discomfort is caused by the fishbone damaging the mucosa. If necessary, you can take oral antibiotics to prevent infection, such as penicillin or cephalosporin, and eat a light diet, mainly liquid diet. 2. Surgery is needed: If the fishbone cannot be removed by gastroscopy, different surgical methods can be adopted according to the results of CT. If the fishbone penetrates the esophagus or aorta, the chest needs to be opened to remove the fishbone. It is recommended that the patient must do a systematic examination in time when the fishbone is stuck in the hospital, and according to the examination results, the doctor will take the appropriate way of treatment.
