In clinical practice, the following three aspects are used to determine whether a patient has a fish spike stuck in the esophagus: 1) the patient has a clear history of ingestion; 2) the patient has clear or certain clinical symptoms, such as pain behind the sternum or a clear foreign body sensation when swallowing food, can be considered to have a fish spike stuck in the esophagus; 3) it can be combined with the relevant 3. The diagnostic value of CT scan of the chest can be further clarified by combining it with relevant imaging examinations. The diagnostic value of a CT scan of the chest is relatively high. A plain film or barium fluoroscopy of the chest is of little significance for clinical diagnosis. Endoscopy is the gold standard for diagnosis of fish spikes in the esophagus and is an effective treatment for fish spikes in the esophagus.
