OBJECTIVE: To determine whether multidetector computed tomography (MDCT) is helpful for early detection of gastroduodenal perforation.
MATERIAL AND METHODS: Fifteen consecutive gastroduodenal perforations for ulcer were recorded in the HIS of a single institution. Reports were analyzed and classified according to the following signs: Was a pneumoperitoneum detected? Was there mention of a perforation site, and how was it depicted (axial or reformatted slices, thin or thick slices)? What were the other described features, including peritoneal fluid, abdominal fat blurring, and bowel wall thickening?
RESULTS: All patients had a gastroduodenal perforation. MDCT identified pneumoperitoneum in 15 of 15 cases as compared with three of nine cases for plain films. The perforation site was seen in eight of 15: it was identified as a defect in the parietal wall (gastroduodenal). Six of eight cases were depicted in axial view. Two of them were only seen on MPR, coronal or sagittal view.
CONCLUSION: MDCT improves the detection rate of pneumoperitoneum and provides critical data for locating the perforation using direct and indirect signs. Multiplanar images seem to improve radiologists' confidence.
