Coins are the most commonly ingested foreign body in the pediatric age group with a peak occurrence in children less than 5 years old. X-rays are considered the gold standard for definitive diagnosis and location of metallic foreign bodies. This study aimed to find a way to decrease radiation exposure by using a metal detector.
19 patients ages 10 months to 14 years with 20 esophageal coins were enrolled in the study. All proximal esophageal coins were detected by the metal detector. 5 patient's failed initial detection of the coin with the metal detector and all of those patients had the coin in the mid or distal esophagus with a depth greater than 7 cm from the skin.
Bottom line: A metal detector may detect proximal esophageal coins. This may have a role in decreasing repeat x-rays.
