Abstract
A 64-year-old woman had undergone subtotal stomach-preserving pancreaticoduodenectomy for locally advanced pancreatic head cancer. She had an uneventful postoperative course with no recurrence. However, approximately 18 months after surgery, she presented with recurrent abdominal pain. Although contrast-enhanced computed tomography abdominal radiographs showed internal stent migration to the residual pancreas, dilatation of the tail side of the pancreatic duct was observed. The impaired internal stent was considered to be the cause of the abdominal pain. An attempt to remove the stent via balloon-assisted endoscopy was unsuccessful as the pancreaticojejunostomy site could not be reached. Consequently, endoscopic ultrasonography-guided pancreatic duct drainage was performed, and a plastic stent was placed through the jejunal site to the stomach. Two months later, the endosonographically/endoscopic ultrasonography-guided created route was dilated, and an endoscopic introducer was inserted into the pancreatic duct. Biopsy forceps were advanced through the sheath, allowing the successful removal of the stent by direct grasping. The symptoms of the patient improved, and she was discharged without complications.
