Treatment choices for infected pancreatic necrosis:surgery debridement or endoscopy drainage?

Abstract

Infected pancreatic necrosis (IPN) is a crucial reason for the poor prognosis of patients with acute pancreatitis,which is complicated and difficult to predict the outcomes. Surgery is an important way to cure IPN,and "step-up approach" is the mainstream mode of IPN treatment. In the era of minimally invasive surgery,the full course endoscopic treatment of IPN has been gradually hot and achieved good outcomes as endoscopic technology' improvement. However,it is controversial that whether technique is better for IPN by surgery debridement or endoscopy drainage,and there is no consensus on the scope of applicability and the timing of intervention. The paper aims to explore the intervention methods,indications and timing of endoscopic and surgical treatment of IPN and elaborate the selection strategies of them in clinical practice,so as to develop individualized treatment options,accurately implement minimally invasive intervention and improve the prognosis.
