Infected walled-off pancreatic necrosis (WOPN) is a severe complication of acute pancreatitis. Surgery in these critically ill patients can be associated with increased morbidity and mortality. Hence, minimally invasive therapies have emerged as an alternative to surgery. Herein, we report a case of severe acute pancreatitis with WOPN which was treated percutaneously with a flexible endoscope through an esophageal self-expanding metal stent using a total retroperitoneal approach. Percutaneous direct endoscopic necrosectomy (p-DEN) using the retroperitoneal route improved the patient’s parameters dramatically with resolution of sepsis without the need for surgery. p-DEN using a flexible endoscope passed through a large bore metal stent shows promise in selected patients with WOPN and can be used in patients who are not ideal candidates for transmural or surgical drainage.
