ENDOSCOPIC THERAPY FOR PANCREATIC PSEUDOCYST AND WALLED-OFF NECROSIS

Abstract

Recently, the endoscopic step-up approach has become the standard treatment for pancreatic pseudocysts or walled-off necrosis following acute pancreatitis. This approach involves minimally invasive, endoscopic ultrasound-guided transluminal drainage and, if necessary, direct endoscopic necrosectomy. Endoscopic treatment is now sufficient for a majority of cases, owing to the development of specialized large-bore, bi-flanged metal stents, and endoscopic additional drainage techniques. However, if the disease extends into the pelvic cavity, it is necessary to consider percutaneous or surgical approaches alongside endoscopic treatment. In this article, we review the progress and current status of endoscopic treatment for pancreatic pseudocysts and walled-off necrosis.
