Abstract

Endoscopic ultrasonography (EUS)-guided pancreatic pseudocyst drainage using a self-expandable metal stent (SEMS) has been reported for satisfactory drainage and endoscopic necrosectomy. Here, we described an interesting case in which successful endoscopic therapy was performed using a new SEMS in infectious walled-off pancreatic necrosis.

Supplement

Endoscopic ultrasonography (EUS)-guided pancreatic pseudocyst drainage using a self-expandable metal stent (SEMS) has been reported for satisfactory drainage and endoscopic necrosectomy [1–3]. Recently, a new SEMS has been developed (NAGI-Stent, Taewoong Company, Seoul, Korea), which is delivered through a 10.5-Fr catheter, and consists of a fully covered 20-mm length and 16-mm diameter stent with bilateral anchor flanges (Fig. 1). A new SEMS makes it possible to create the fistula between pancreatic pseudocyst and GI tract wall if the adhesion is not present (Fig. 2). In addition, it allows direct endoscopic necrosectomy easily again and again through the large bore stent in patients with walled-off pancreatic necrosis. In conclusion, a new SEMS must allow safe and reliable procedure in the setting of pancreatic pseudocyst and walled-off necrosis.
