Predictive factors and outcomes of endoscopic necrosectomy in patients with acute pancreatitis and walled-off necrosis

Figure 1 Magnetic resonance imaging and endoscopic ultrasound guided drainage of lumen-apposing metallic stents. A: Magnetic resonance T2-weighted imaging coronal; B: Axial views showing walled-off necrosis of the pancreas with significant debris; C: Endoscopic ultrasound (EUS) reveals a large walled-off necrosis with echogenic contents and debris (orange arrow); D: EUS-guided lumen-apposing metallic stents (LAMS) are being placed, with distal flanges (yellow arrow) deployed; E: Both distal flanges (yellow arrowhead) inside the cavity and proximal flanges (orange arrowhead) in the gastric cavity are deployed seen in EUS; F: Endoscopic image post-deployment of LAMS and pus seen oozing out from out the LAMS.
