Bones stuck in the esophagus for two years need to be diagnosed if there is a foreign body stuck in the esophagus, if there is a bone stuck in the esophagus for two years may have caused septicemia, infection, perforation, and already have comorbidities. Therefore, if no bone is detected, there may be no foreign body in the esophagus. If there is indeed a need for gastroscopy, the foreign body needs to be removed promptly, otherwise it may cause infection, perforation or even more serious complications in the esophagus. In addition, if the foreign body cannot be removed successfully under gastroscopy, it is necessary to use esophagoscope to try to remove it. If it still cannot be removed, the foreign body has penetrated the esophagus and pierced the esophageal wall, and caused chest symptoms such as pneumothorax, and if necessary, thoracic surgery is required.
