Core Tip

Core tip: The use of self-expanding and lumen-apposing metal stents for the drainage of walled-off necrosis has revolutionised the treatment options and outcome of this disease. Conventionally, these stents are placed by endoscopic ultrasound-guidance but under fluoroscopic control. We could demonstrate that all steps of the stent insertion are visible endosonographically which allows safe and controlled stent placement. Without the need for fluoroscopy and consequent radiation protection regulations, this procedure becomes available in the endoscopy unit and at the bedside of critically ill patients.
