Cost-Effectiveness Analysis Comparing Lumen Apposing Metal Stents with Plastic Stents in the Management of Pancreatic Walled-Off Necrosis

EUS-guided transmural drainage is effective in the management of pancreatic walled-off necrosis (WON). A lumen-apposing metal stent (LAMS) has recently been developed specifically for the drainage of pancreatic fluid collections showing promising results. However, no cost-effectiveness data have been published in comparison to endoscopic drainage with traditional plastic stents (PSs). The aim is to compare the cost-effectiveness of LAMSs to PSs in the management of WON.
