Abstract:
A 2-year-old girl ingested a ballpoint pen, which was found on chest x-ray to have lodged in the lower esophagus and stomach. The pen, which measured nearly 15 cm in length, was removed via rigid esophagoscopy without complication. To the best of our knowledge, this is the longest nonflexible foreign body ingested by a young child ever reported in the English-language literature. We describe the presentation of this case and the current guidelines for safety as enumerated in the Small Parts Regulations established by the U.S. Consumer Product Safety Commission.
