Some of the coins swallowed by 2.5 year old babies can be expelled on their own, while endoscopic or surgical treatment is the mainstay of treatment for those who fail to expel the coins on their own and have gastrointestinal obstruction. Smaller coins that are swallowed by children can usually be expelled on their own, and most of them have a good prognosis. However, there are cases that cannot be eliminated on their own and require endoscopic treatment or even surgical removal of the foreign body, which is mainly based on the age of the child, the size of the coin, the location and duration of the coin, and the presence of complications. When a child accidentally swallows a coin, attention needs to be drawn to the child’s vital signs and the presence of other uncomfortable symptoms should be closely monitored, should be timely to the hospital, and under the guidance of the doctor for treatment.
