Infected pancreatic necrosis is a major local complication in the later stages of acute necrotizing pancreatitis,and it is the main cause of prolonged hospitalization and death.Minimally invasive step-up therapy is currently considered superior to traditional open surgery,and endoscopic step-up therapy is internationally recommended as the preferred intervention method because it has fewer complications,less hospitalization time,and less hospitalization cost than minimally invasive surgical procedures.Minimally invasive step-up therapy includes initial endoscopic transmural drainage or percutaneous drainage,and endoscopic transgastric necrosectomy,video-assisted retroperitoneal debridement,or sinus tract endoscopy if necessary.
