Long-Standing Abdominal Complaints and Hyperamylasemia Due to Foreign Body Ingestion

A 38-year old man was referred for endoscopic retrograde cholangiopancreatography. A gastroduodenoscopy performed elsewhere for chronic dyspepsia showed a foreign body in the duodenum that was considered to be an endoprothesis in either the pancreas or biliary tract. His medical history showed previous hospital admissions as a result of dyspepsia in 2012 and 2015, and the patient had been homeless for several months in 2012. Laboratory tests in 2012 showed an increased amylase level of 575 U/L (normal range, 0–100 U/L), but at these previous admissions the patient repeatedly had left the hospital before further imaging had taken place.
