INTRODUCTION: Retrievable plastic biliary stents are usually inserted endoscopically. When endoscopic placement fails, radiological percutaneous transhepatic placement is indicated. We report the occurrence of a case of delayed duodenal perforation with @entity733 formation after radiological placement of a plastic stent. To the best of our knowledge, this is the first report of this complication after radiological stenting. CASE PRESENTATION: A 58-year-old Caucasian @entity1 had a mass 30 mm in size in the head of the @entity3883 . He was referred for radiological insertion of plastic biliary stents after a failed endoscopic attempt. The procedure was uneventful, and the @entity1 was discharged. Two weeks after the procedure, the @entity1 presented with an acute abdomen and signs of @entity295 . Computed tomography revealed erosion of the posterior duodenal wall from the plastic stent, and a large retroperitoneal @entity733 . The @entity733 was drained under computed tomography guidance, and the migrated stent was removed percutaneously with a snare under fluoroscopic guidance. Our @entity1 had an uneventful recovery and was discharged after a week. CONCLUSION: Late retroperitoneal duodenal perforation is a very rare but severe complication of biliary stenting with plastic stents. Gastroenterologists, surgeons and radiologists should all be aware of its existence, clinical presentation and management.
