RT Journal Article SR Electronic T1 Buried coin in the gastric mucosa JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP bcr-2018-227622 DO 10.1136/bcr-2018-227622 VO 12 IS 1 A1 Dominic Ti Ming Tan A1 Yih Chyn Phan A1 Edmund Leung YR 2019 UL http://casereports.bmj.com/content/12/1/bcr-2018-227622.abstract AB A 29-year-old man presented to the Accident and Emergency department with abdominal cramping following ingestion of a 50 p coin 2½ weeks prior to presentation. He had not observed it pass in his stools. An abdominal radiograph confirmed the presence of the 50 p coin in his stomach. Subsequently, he had an oesophagogastroduodenoscopy (OGD) performed with a failure to visualise the coin. 1½ weeks later, he returned to the department as he was still unable to observe its passing in his stools. A repeated abdominal radiograph and a CT of the abdomen and pelvis revealed that the coin was still in his stomach. A second OGD was performed once again with a failure to visualise the coin. It appeared that the coin had migrated into his gastric mucosa.
