Button batteries and typical swallowed foreign bodies can be differentiated in high-resolution X-Rays

Two Stacked Coins Mimicking an Esophageal Button Battery: A Case Presentation and Review of the Literature

As button battery (BB) ingestion has become a popular topic with growing public awareness in recent years, pediatric otolaryngologists maintain a high index of suspicion for this diagnosis. Several recent reports have revealed the possibility for benign objects to masquerade as BBs, such as two coins stacked together or a coin with different metals in concentric rings. A 4-year-old female presented to the ED after unwitnessed ingestion of a foreign body. The child was reportedly seen playing with her sister's coin collection prior to the acute onset of drooling and dysphagia. She was vitally stable and without any shortness of breath, stridor, or wheezing. Plain film X-ray revealed a round, metallic object with a double density on the frontal view and beveled step-off on the lateral view at the level of the thoracic inlet. Due to high radiographic concern for BB ingestion, the patient was taken emergently to the operating room for a rigid esophagoscopy. A metallic object was seen at the thoracic inlet and removed with Magill forceps. The object was found to be two coins stuck together, with a smaller coin in the center of a larger coin mimicking the shape of a BB. The patient was discharged the next day without complication. This case highlights stacked coins as a radiologic masquerade for BBs as well as the emphasis on prompt esophagoscopy for both identification and removal. Radiographic densities alone cannot be relied upon to distinguish BBs from more innocuous objects, and esophagoscopy remains the mainstay of management for pediatric esophageal foreign bodies.

Pediatric Foreign Body Ingestion: Complications and Patient and Foreign Body Factors

Background: Management of the child who has swallowed a foreign body should be guided by the risk of complication. Objective of the Review: This review discusses the patient and foreign body characteristics most likely to be associated with complications. Discussion: Most swallowed foreign bodies will pass through the GI tract without complication. Children with pre-existing GI tract abnormalities of any sort, or those who swallow higher-risk foreign bodies, are at higher risk. Higher-risk foreign bodies include long, sharp, or pointed objects, button batteries, and small magnets. Nearly any child who presents to an Emergency Department or other acute care setting after foreign body ingestion should undergo plain radiography; other forms of imaging may also be appropriate. Primary care providers may opt for an initial observation period when there is lower risk of complication. Esophageal button batteries should be emergently removed; other esophageal objects should be promptly removed or, if low risk, allowed a brief period to pass spontaneously. Most lower GI tract foreign bodies will pass spontaneously. Prevention, while not always possible, is preferable to management of foreign body ingestion. Conclusions: Management strategies for children who have swallowed foreign bodies can be optimized by considering relevant patient and foreign body factors, and how they contribute to the risk of complication.

Association between the corrosion of ingested lithium button battery in the esophagus and its complications in pediatric patients

PURPOSE

The incidence of lithium button battery ingestion has been increasing recently, which results in severe complications. We aimed to demonstrate the association between the corrosion of lithium button batteries in the esophagus on radiographs and their complications.

METHODS

The nine pediatric patients included in this study were classified into two groups based on the presence of severe complications. The presence and degree of corrosion on plain radiographs were evaluated. The degree of corrosion was classified into the following three grades; none: 0%; moderate: 1-50%; severe: 51-100%. Fisher's exact test was used for statistical analyses.

RESULTS

Of the nine patients, five showed complications. The number of patients who had grade none, moderate, and severe degrees of corrosion was three, four, and two, respectively. The incidence of severe complications differed significantly between the incidence of lithium button batteries' contour (without vs. with severe complications [presence/absence of corrosion] = 1/3 vs. 5/0, respectively; P = 0.0476). In cases with "none" degree of corrosion, all three cases had no complication, and in cases with a "severe" degree of corrosion, all two cases had complications.

CONCLUSION

The cases with the presence of corrosion of lithium button batteries had a higher tendency to have severe complications. Therefore, physicians should anticipate the presence of severe complications in pediatric patients with corrosion more than those without corrosion.
