Endoscopic management of PFCs is an alternative to surgery <span>[1]</span>. Classic strategies include access to the collection under endoscopic ultrasound (EUS)-guidance and placement of several double-pigtail stents. PFCs containing organized necrosis are classified as walled-off necrosis (WON). In those cases necrosis is hardly evacuated and will require necrosectomy in most cases. Every necrosectomy session needs prior removal of the stents, dilatation of the tract, debridement and placement of new stents adding up a considerable overall cost to the intervention.
