Acute
pancreatitis (AP) is a disease of varying severity with acute
necrotizing pancreatitis (ANP) being the severe form of AP. ANP needs
multidisciplinary management and is associated with significant
mortality and morbidity. Local complications of ANP viz. acute necrotic
collections (ANC) and walled off pancreatic necrosis (WOPN) need
intervention if they are associated with symptoms, sepsis or worsening
organ failure. As surgery is associated with higher morbidity and
mortality, there is paradigm shift in the management of these local
complications with an increased emphasis on conservative and minimally
invasive treatment approach. Image-guided percutaneous drainage (PCD) is
a minimally invasive intervention that helps in drainage of infected
collections, temporizes sepsis and improves outcomes in these patients.
The present review discusses the utility of various percutaneous
interventions in management of variety of pancreatic collections
occurring in ANP. The available evidence, technical details and
complications and emerging innovations in the field are also summarized.
