[Endoscopic, transmural drainage and necrosectomy for walled-off pancreatic necrosis]

For many decades the treatment of pancreatic necrosis has been surgical necrosectomy with associated high mortality rates. In recent years several minimally invasive strategies have been introduced. Endoscopic, transmural drainage and necrosectomy is a new, effective and relatively safe method compared to other treatment modalities. The success rate can probably be increased by combining endoscopy with other minimally invasive techniques. We here describe the method and review the present literature on this topic.
