Core Tip	This case report describes a rare complication of recurrent walled-off necrosis caused by mechanical occlusion of a branch cavity ostium by the edge of a lumen-apposing metal stent. This was successfully managed by endoscopic removal of the lumen-apposing metal stent, followed by salvage drainage with plastic stents, resulting in complete resolution of symptoms and radiographic findings. The case highlights a novel failure mechanism that underscores the importance of precise stent positioning and the effectiveness of this endoscopic salvage approach.
