Summary: endoscopic therapies for walled-off necrosis

Acute pancreatitis ranges from self-limited pain to high-risk necrotizing pancreatitis with significant morbidity and mortality. In the setting of walled-off necrosis, intervention on these collections may be necessary, particularly in the setting of infection, biliary or intestinal obstruction, pain from mass effect, or disconnected pancreatic duct syndrome. Necrotic collections require physical debridement of the solid debris. This technology document provides an overview of the tools required for endoscopic transmural drainage and direct endoscopic necrosectomy.
