LAUSR

re 1. A, Preprocedural abdominal MRI demonstrating a large (12.3 7.4 6.4 cm) complex fluid collection with a thick outer wall surrounding ancreatic body (arrow) and suspected disruption of the pancreatic duct (arrowheads). B, EUS view demonstrating the LAMS catheter (arrow) inside the collection, and the distal end of the deployed stent (arrow). C, Upper endoscopic view showing dilation of the cystgastrostomy by f a wire-guided dilating balloon. D, Upper endoscopic view showing bleeding at the proximal end of the LAMS (gastric side). E, Arteriographic showing the deployed LAMS (arrow) and no evidence of extravasation of contrast material. F, Duodenoscopic view revealing the previously d cystgastrostomy stent on the gastric body. A hemostatic clip is seen at the site of active bleeding underneath the stent. G, EGD view demonng the gastric side of the cystgastrostomy without bleeding. H, MRI revealing nearly resolved walled-off necrosis (arrow). I, EGD views before and after (right) LAMS removal. MRI, magnetic resonance imaging; LAMS, lumen-apposing metal stent. The arrow represents the place where tent was.
