Novel classification system for walled-off necrosis: a step toward standardized nomenclature and risk-stratification frameworkThe optimal therapeutic approach for walled-off necrosis (WON) is not fully understood, given the lack of a validated classification system. We propose a novel and robust classification system based on radiologic and clinical factors to standardize the nomenclature, provide a framework to guide comparative effectiveness trials, and inform the optimal WON interventional approach.
Predicting success of direct endoscopic necrosectomy with lumen-apposing metal stents for pancreatic walled-off necrosisDirect endoscopic necrosectomy (DEN) with lumen-apposing metal stents (LAMSs) is increasingly used in the management of pancreatic walled-off necrosis (WON). However, it still remains unknown which patients will fail to respond to DEN with LAMSs and require additional surgical intervention. Therefore, the aim of our study was to explore predictors of successful DEN with LAMSs for pancreatic WON.
Visceral artery pseudoaneurysms in necrotizing pancreatitis: risk of early bleeding with lumen-apposing metal stentsVisceral artery pseudoaneurysm (PSA) in necrotizing pancreatitis (NP) is associated with significant morbidity and mortality. This study aimed to evaluate the incidence, clinical presentation, management, and outcomes of PSA in NP.
Cost-effectiveness analysis comparing lumen-apposing metal stents with plastic stents in the management of pancreatic walled-off necrosisEUS-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 that shows promising results. However, no cost-effectiveness data have been published in comparison with endoscopic drainage with traditional plastic stents (PSs). Our aim here was to compare the cost-effectiveness of LAMSs to PSs in the management of WON.
