Core Tip

Core Tip: Percutaneous endoscopic necrosectomy (PEN) is an approach for the walled-off necrosis (WON) developing in the retroperitoneal space distant from the stomach or duodenum. Surgical necrosectomy is at high risk for older and frail patients, and less invasive drainage methods are ideal. We performed PEN for elderly with WON and were able to complete the treatment safely without complications.
