| Summary: | Background: Endoscopic pancreatic stenting is an effective way to relieve the stricture of the pancreatic duct. However, proximal stent migration presents a threat to the patient and a challenge to the doctor. The limited space in the pancreatic duct often prevents the operation of suitable devices for stent removal. Case presentation: A 34-year-old man with painful chronic pancreatitis received endoscopic retrograde cholangiopancreatography (ERCP) and insertion of a pancreatic plastic stent, with 8.5 Fr in diameter and 12 cm in length. A year later, radiography revealed that the proximal end of the stent rested in the pancreatic tail while the distal end rested in the branch duct. Both balloon and rat-tooth forceps were used but failed to retrieve the stent. A week later, a second ERCP was performed. After dilation with a 10-mm balloon, a small amount of bleeding was noticed and a crack appeared in the wall of the branch duct. Consequently, the distal end of the stent was released. Then, rat-tooth forceps was used to grasp the distal end, and the stent was pulled out successfully. Conclusions: For a proximally migrated pancreatic stent stuck at both ends, a strategy of maximum dilation can be used cautiously to retrieve the stent.
