Core tip: Endoscopic ultrasonography (EUS)-guided drainage of pancreatic pseudocysts and walled-off necrosis has become an established less invasive management of these difficult to treat complications of acute and chronic pancreatitis. New developments such as forward-viewing echoscopes and exchange-free delivery systems for the insertion of stents and drainages have simplified the technically challenging procedure. Specially designed self-expanding metal stents aim on improved drainage of the cyst content. This article reviews new EUS-guided techniques and their indications.
