We report two cases of accidental ingestion of a press-through package (PTP) . Case 1 was a 57-year-old woman who visited our hospital and stated that she possibly swallowed a PTP. Abdominal CT did not detect a foreign body. During upper gastrointestinal endoscopy, the PTP was identified directly in the esophagus and removed endoscopically. Case 2 was a 75-year-old woman who visited our hospital because of ingestion of a PTP. Abdominal CT revealed an object with high-density opacity, which was suspected of being a PTP, in the esophagus. Under the diagnosis of ingestion of a PTP, upper gastrointestinal endoscopy was performed and the PTP was removed.
Abdominal CT imaging is generally useful for correct diagnosis of ingestion of a PTP, although CT sometimes cannot detect a PTP depending on the materials it is made of. It is noteworthy that the materials that make up a PTP affect various CT imaging results.
