Limited %R 10.4253/wjge.v4.i9.432 %X Covered self-expandable metal stents were developed to overcome tumor in-growth through the metal mesh. Stent migration is one of their malfunctions. Recently, the partially covered wallflex stent (PCWS) was developed with flared ends to prevent migration However, difficulty has been reported in its removal. We describe the removal of a PCWS embedded in mucosal hyperplasia at the uncovered proximal flared end, visualized by using SpyGlass cholangioscopy. %K Self-expandable metal stent %K Complication %K Mucosal hyperplasia %K Stent removal %U http://www.wjgnet.com/1948-5190/full/v4/i9/432.htm
