Final answer:
There is essentially no condition where a button battery swallowed and lodged in the esophagus should not be removed. It is a medical emergency due to the risk of severe internal burns and potentially fatal injuries. Immediate medical assistance is necessary.
Step-by-step explanation:
The condition where a button battery in the esophagus does not need to be removed is virtually nonexistent. If a button battery is swallowed, it can lead to severe internal burns and even death. Therefore, it is a medical emergency that typically requires prompt removal.
Button batteries like the type used in watches, pacemakers, or calculators, are small and can easily get lodged in the esophagus especially in small children. If anyone swallows a button battery it is crucial to seek immediate medical assistance rather than waiting for it to pass naturally.
The ingestion of button batteries is a serious medical concern, and there is no safe condition under which they can remain in the esophagus without the risk of significant injury or fatal consequences.
