Migration of a Lumen-Apposing Metal Stent into the Colon

The introduction of lumen-apposing metal stents (LAMS) has been an important development in the management of pancreatic fluid collections. Stent migration out of pancreatic fluid collections into the stomach has been reported, despite the special anti-migratory design of the bi-flanged stent. Data on stent migration rates remain sparse, with some studies suggesting a migration rate of 3.3–5%. There have been no reported cases of LAMS migration outside of the stomach. We describe the first reported case of a transgastric LAMS migrating from the stomach and passing into the colon
