This patient accidentally swallowed a needle. The chest X-ray shows it has passed into the abdomen.
If an object - which is known to be radio-opaque - is swallowed, then a chest X-ray is the first investigation.
If the object has passed beyond the gastroesophageal junction into the abdomen then it will usually pass safely through the rest of the gastrointestinal tract.
If the object is sharp then some surgeons will request repeat images to ensure it safely passes beyond the stomach. An abdominal X-ray is also indicated if gastrointestinal symptoms develop.
An abdominal X-ray was performed when mild abdominal pain developed. There was no evidence of perforation on this X-ray, or the erect chest X-ray, and the needle passed safely.
This self-harming patient swallowed a razor blade. It is located on the right side of the abdomen and is therefore beyond the stomach. It passed throughout the rest of the bowel without complication.
