A case of stent migration into the main pancreatic duct successfully removed by Soehendra stent retriever

Abstract

A 71-year-old Japanese woman was admitted to investigate the cause of common bile duct dilatation. She had no previous history of pancreatic diseases. Endoscopic retrograde cholangiopancreatography (ERCP) was performed on the admission day. During ERCP, biliary cannulation was difficult and we used the pancreatic duct guidewire technique. To prevent post-ERCP pancreatitis, a pancreatic stent was placed into the main pancreatic duct, but was accidentally migrated into the duct. The stent could not be retrieved by various devices because of the narrow pancreatic duct.
We performed ERCP again on hospital day 5 and successfully removed the stent using a 5-French Soehendra stent retriever (SSR-5) . The patient was discharged on hospital day 7 without any other adverse events. Pathological examination of biopsy specimens of the common bile duct revealed no malignancy. In cases of stent migration into the non-dilated pancreatic duct, SSR-5 may be useful for the stent removal.
