Core tip: Biliary stent migration complicated by duodenal perforation is rare and should be included in the differential diagnosis of those presenting with abdominal pain after endoscopic retrograde cholangiopancreatography with stent placement and physicians caring for these patients should be aware of such complication. To reduce the chance of stent migration, endoscopists should assess for the size and shape of the stent in each patient.
