| EUS-guided transenteric drainage of peripancreatic fluid collection or of the biliary tree, including the gallbladder (GB) has been a well-established procedure. However, conventional stents still have a chance of migration or leakage that can lead to serious complications. A fully covered self-expandable metal stent (FCSEMS) designed as a lumen-apposing stent (Axios, Boston Scientific, USA) has been developed. However, that lumen-apposing stent has a complex delivery system and is technically challenging. A new FCSEMS for lumen apposition with a conventional stent delivery system (Niti-S Spaxus, Taewoong Medical Co., Ltd., Korea) is developed as an effective and easy procedure. The diameter of the flange at both ends was to 25 mm to anchoring. After deployment, the anchoring flanges can be folded back to hold the two luminal interfaces in apposition. The diameter of the stent is 8, 10, 16 mm and the length is 20 mm, but the distance between the flanges is 7 mm after folding back with deployment. This stent is delivered with a 10.0-F conventional delivery system, so the stent can be inserted smoothly via the working channel of an echoendoscope, and deployed readily. In conclusion, new lumen-apposing stent can be effective for EUS guided drainage and access for biliopancreatic lesions. |
