Usefulness of ultrasonography in gastric foreign body retention.
Foreign-body ingestion occurs frequently in childhood. The diagnosis of ingestion is usually made by plain film radiography. Ultrasound is not routinely used in the investigation of gastric foreign bodies because of the limitations imposed by intestinal gas. This drawback can be overcome by distending the stomach with an anechoic liquid, which acts as an acoustic window. In a child who had ingested a coin, US performed after drinking tea was diagnostic and showed a hyperechoic image with an acoustic shadow inside the stomach. We believe that US is an appropriate technique for follow-up of gastric foreign bodies.
