X-ray diagnosis with a bloating agent for foreign object ingestion

Figure 1 X-ray image. A: Initial X-ray image showing the presence of a foreign object in the patient’s abdomen; B: Abdominal X-ray image taken after oral administration of a bloating agent. Gastric air bubbles produced after administration of the bloating agent provided sufficient distension and negative contrast to confirm that the battery was inside the stomach; C: Chest X-ray image during removal of the foreign object. A magnetic catheter was used in combination with a balloon catheter to attract and remove the battery under fluoroscopic guidance.
