Biliary stent migration is one of the late complications of endoscopic retrograde cholangiopancreatography. Most of the biliary stent migration is asymptomatic and successfully managed by stent removal. A 66-year-old man with unresectable pancreatic cancer, common bile duct obstruction, and duodenal third portion obstruction underwent endoscopic plastic biliary stent placement and duodenal uncovered metallic stent placement in two separate sessions. After 3 weeks from the duodenal stenting, he presented with hematemesis. Urgent esophagogastroduodenoscopy and magnetic resonance imaging showed hemobilia. The patient recovered with conservative managements. Cross-sectional imagings done 2 months later demonstrated the penetration of the biliary stent into portal vein. Here, we present a case of delayed hemobilia caused by penetration of biliary plastic stent into the portal vein.
