Multidetector computed tomography to detect ingested press-through packages: utility of multiplanar reconstruction imaging in the emergency department

CaseWe investigated the usefulness of multidetector computed tomography during examination in the emergency department to detect the location of press-through packages that had been inadvertently swallowed. In three patients, four press-through packages were detected on multi-planar reconstruction of multidetector computed tomography images, with three lodged in the esophagus and one in the stomach. OutcomeThe multidetector computed tomography detection rate of press-through packages was 100% in patients who realized they had swallowed the packages by mistake. After diagnosis, press-through packages in the esophagus were immediately removed endoscopically. ConclusionThere are few reports on the usefulness of multi-planar reconstruction images by multidetector computed tomography during examinations in the emergency department for the diagnosis of foreign bodies in patients who have mistakenly swallowed press-through packages. Detecting the location of the packages provided useful information regarding the strategy for their removal. Therefore, proactive multidetector computed tomography use in the emergency department could be beneficial for patients who have inadvertently swallowed press-through packages.
