Abstract:
A 46-year-old schizophrenic male presented to the emergency department (ED) after deliberate ingestion of an undetermined number of open razor blades. Abdominal radiograph revealed one razor blade but raised suspicion of a second blade which was subsequently confirmed by digital tomosynthesis (DTS), seen as two razor blades superimposed upon each other placed at slightly different angles. A careful search was made during endoscopy and the two razor blades were retrieved from the stomach and duodenum, respectively. This case illustrates the use of digital tomosynthesis as a smart, timely, cost-effective, and low-dose alternative to conventional computed tomography (CT) that can be conveniently employed in the ED for foreign body localization.
