Methods of lower esophageal foreign body removal in children include CT examination for localization, endoscopic removal, and surgical treatment. A foreign body in the lower esophagus is when food or other foreign objects are temporarily lodged or embedded in the lower esophagus during swallowing. If the foreign body stays in the esophagus for a long time, it may cause damage, perforation, infection and other risks to the esophagus. The methods of removing foreign bodies from the lower esophagus of children are as follows. 1. CT localization: Chest CT examination should be done first to clarify the location of the foreign body, whether there is perforation of the esophagus and the relationship with other adjacent organs, etc., so as to prepare for the next step of removal. 2. Endoscopic removal: Since children’s compliance is poor, general anesthesia is usually needed. After the specific location of the foreign body is determined by chest CT, the foreign body will be removed under fiberoptic esophagoscopy or electronic esophagoscopy with instruments such as rat-toothed forceps and mesh basket forceps. 3. Surgery: If the foreign body in the lower part of the esophagus cannot be removed under endoscopy, surgery is needed to remove the foreign body. If a child is found to have a foreign body in the lower esophagus, it is recommended to consult a doctor in time to remove the foreign body in order to avoid adverse effects.
