Foreign Body Ingestion in Children
A 3-year-old boy is brought to the emergency department 6 hours after his mother witnessed him swallow a 20 halala coin. He has had no vomiting, drooling, chest pain, or refusal to eat. There is no stridor. Radiography of the neck, chest, and abdomen shows a single round radiopaque object in the gastric fundus with no double ring or halo. Which is the most appropriate management?
- A.Discharge with observation and follow up radiographyCorrect
- B.Immediate endoscopic retrieval of the coin
- C.Urgent exploratory laparotomy for removal
- D.Contrast enhanced computed tomography of the abdomen
Explanation
An asymptomatic child with a single blunt object that has already reached the stomach can be safely managed with outpatient observation, because more than 90 percent of such foreign bodies pass spontaneously through the gastrointestinal tract without complication. Parents are advised to maintain a normal diet, watch for vomiting, abdominal pain, fever, or hematemesis, and inspect the stools, with a repeat radiograph arranged if the object has not passed. The first step in any suspected ingestion, after ensuring airway and hemodynamic stability, is a radiograph of the neck, chest, and abdomen to localize the object, and computed tomography is reserved for objects not visible on plain films or when perforation is suspected. Endoscopic removal is indicated for sharp or pointed objects, objects longer than 5 cm, more than one magnet or a magnet with another metallic object, any symptomatic patient with pain, vomiting, drooling, or fever, an object impacted in the esophagus, and a gastric object that fails to progress beyond about 4 weeks. The single most important exception is the button battery, which must be removed emergently within 2 hours if lodged in the esophagus because it generates a hydroxide current that causes liquefactive necrosis and can perforate into the aorta; the double ring or halo sign on radiograph distinguishes it from a coin, and its absence here confirms a simple coin. Laparotomy is reserved for perforation or obstruction.
Why each option
- A.
- Correct. An asymptomatic blunt object already in the stomach passes spontaneously in over 90 percent of cases and needs only observation.
- B.
- Endoscopy is indicated for sharp, long, or magnetic objects, button batteries, esophageal impaction, symptoms, or failure to progress beyond 4 weeks.
- C.
- Laparotomy is reserved for perforation, obstruction, or failed endoscopic retrieval.
- D.
- Computed tomography adds radiation without benefit when the object is already clearly localized on plain radiography.
