A CASE OF ILEAL PERFORATION BY PRESS-THROUGH-PACKAGE (PTP) DIAGNOSED BY CT FINDINGS

Abstract

We present a rare case of ileal perforation by press-through package (PTP). An 83-year-old man was referred to the hospital because of vomiting and tachypnea. During the day, abdominal distention worsened and a diagnosis of ileus was made. By abdominal CT findings, a diagnosis of intraperitoneal abscess was made and drainage therapy was performed. The abscess was decreased, but a foreign body that had been suggested by CT remained. So he underwent an operation and was finally diagnosed as an ileal perforation by PTP. The perforation site was found at the 6cm oral side from the terminal ileum. There have been several cases of perforation of the small intestine by PTP in the Japanese literature. This condition was difficult to diagnose before operating because of the radiotransparency of PTP, but we were able to detect it as a foreign body by CT examination. We report a rare case of ileal perforation by PTP which was diagnosed by CT findings.
