We report two cases of gastrointestinal perforation caused by accidental ingestion of a press-through package （PTP）. Case 1：an 87-year-old woman who was suffering from epigastralgia. Abdominal CT revealed a high-density opacity, suspected to be a PTP, in the duodenum with surrounding free air. Under the diagnosis of duodenal perforation, upper gastrointestinal endoscopy was performed. The PTP in the duodenum was removed endoscopically, and a perforation was identified and clipped. Unfortunately, endoscopic treatment was unsuccessful. Partial resection of the duodenum and jejunum was performed on hospital day 48. Case 2：a 60-year-old woman visited his physician because of upper abdominal pain. CT showed intraabdominal free air, and the patient was transported to our hospital. The foreign body and region of perforation could not be detected on a repeat CT. At laparotomy, a perforation with partial exposure of a PTP was found in the ileum. The perforated portion of the ileum was surgically resected. Accidental ingestion of PTP should be kept in mind as a cause of gastrointestinal perforation. Abdominal CT imaging is useful for correct diagnosis of gastrointestinal perforation caused by PTP. It is noteworthy that the materials of PTP affect various features of CT imaging.
