Endoscopic retrieval of two proximally migrated plastic pancreatic duct stents.

Plastic stent migration is an important complication of pancreatic duct (PD) stenting, with distal (downstream) migration being more common than proximal (upstream) migration. While the distal stent migration into the duodenum is rarely of any clinical consequence, proximal stent migration can cause serious complications, including obstructive pancreatitis. The endoscopic removal of proximally migrated stents is difficult because of the small diameter of PD, the bended and sometimes tortuous course of PD, the presence of strictures, and a lack of dedicated endoscopic accessories. We report a rare case of endoscopic retrieval of two proximally migrated plastic stents from PD.
