Retrieval of migrated pancreatic stent: “stent-in-stent” technique

A 13-year-old boy, in whom a 10-Fr, 10-cm pancreatic stent had been placed 3 months earlier to manage chronic pancreatitis and pain syndrome, was admitted for stent exchange. On endoscopic retrograde cholangiopancreatography, the pancreatic stent was not visible at the papilla. The pancreatic duct was cannulated with a 0.025-inch guidewire (VisiGlide; Olympus America, Center Valley, Pennsylvania, USA). Fluoroscopy showed that the stent had migrated deeply into the pancreatic duct and that the guidewire had passed through the stent ([Fig. 1 a, b]).
