INTRODUCTION: We report the first case of a choledocholithiasis migrating into the main pancreatic duct (MPD) due to catheter manipulation during endoscopic retrograde cholangiopancreatography (ERCP).
CASE PRESENTATION: A 57-year-old woman complaining of vomiting was diagnosed with acute cholangitis and pancreatitis due to choledocholithiasis. During ERCP, the stone migrated from the papilla into the MPD due to the pushing motion of the catheter. However, the ERCP session was completed after biliary sphincterotomy without intervention in the MPD because the migration was not noticed. The migrated stone became apparent on computed tomography the following day. The second ERCP revealed the stone measuring 5 mm in the MPD. After pancreatic sphincterotomy, a pancreatic stent was placed, which improved the obstructive pancreatitis.
CONCLUSION: Endoscopists performing ERCP should be aware of this rare but serious complication.
