A 72-year-old man presented with a complaint of epigastralgia that was not improved by an antacid. He was referred to our department for further examination, where abdominal computed tomography and endoscopic ultrasonography resulted in a diagnosis of peritoneal dissemination of pancreatic cancer. We planned to start chemotherapy, but he was admitted to our hospital with nausea and vomiting. Gastroendoscopy revealed a malignant gastroduodenal obstruction. We then deployed a partially covered duodenal metallic stent on the obstruction. However, the stent migrated to the esophagus a few days later, and could not be removed due to mucosal hyperplasia at the partially covered site. This adverse event is rare. We review the literature to consider indications and problems with covered stents.
