Endoscopic removal of a migrated cystogastrostomy double pigtail stent through a pancreatico-duodenal fistula tract.

A common complication of pancreatitis is pseudocyst formation. Endoscopic drainage is a widely used treatment for pancreatic pseudocysts, and offers a definitive solution in approximately 75% of cases. Drainage-related complications may be related directly to the procedure or may occur later as stents and drains migrate or erode into adjacent structures. Procedure-related complications included bleeding, pancreatitis, and infection while stent-related complications may involve dislocation or clogging with subsequent infection. This report is the first description of the successful endoscopic removal of a migrated cystogastrostomy double pigtail stent through a pancreatico-duodenal fistula tract that developed more than six years after the stent was originally misplaced into a pseudocyst.
