Conventional endoscopic drainage of symptomatic pancreatic pseudocysts has its limitations when the content of the collection is nonfluid. This leads to obstruction of placed flap stents; it requires the placement of an irrigation catheter and repeated implantation of several stents. Herein we describe the temporary use of a special self-expanding partially covered metal mesh stent, which was designed to keep the pancreaticogastrostomy open for drainage of walled-off necrosis and for further endoscopic necrosectomies. The stent has a diameter of 20 – 25 mm and a length of 50 mm and was placed following the first transgastric removal of necrotic masses. After a treatment period of 7 – 11 days involving 2 – 3 endoscopic procedures we achieved clinical success, defined as complete removal of necrotic masses, in all cases without major complications.
