The management of acute necrotizing pancreatitis (ANP) has undergone a change of paradigms during the last 2 decades with a decreasing impact of surgical interventions. Modern ANP management is done conservatively as long as possible and therapeutic approaches aim at volume resuscitation, pain management and early enteral nutrition. The diagnostic gold standard of contrast-enhanced CT scan helps to evaluate the extent of necrosis of the pancreas, which correlates with the risk of tissue infection. The crucial point for decision making is the proven existence of infected pancreatic necrosis. This can be achieved by diagnostic needle aspiration of the necrotic material and staining to prove bacterial and/or fungal infection. In case of infected necrosis - besides calculated antimicrobial treatment - an interventional or surgical approach is required to prevent systemic septic progression of the disease. As the first step, percutaneous interventional drainage and spilling of the necrosis are preferable. In case of insufficient clearing of the infectious focus, a step-up approach must be considered, which implies a retroperitoneoscopic or transabdominal minimally invasive necrosectomy and drain placement. Postoperatively, a continuous lavage should be performed using these drains. In case of further deterioration of the patient or development of associated intra-abdominal complications (e.g. bowel perforation or uncontrolled bleeding), an open surgical intervention must always be regarded as a salvage therapy and this offers the possibility to control complications and perform a further necrosectomy and extensive lavage for focus control. However, associated morbidity (e.g. pancreatic fistula, fluid collections, pseudocysts) is about 50-60% and mortality up to 20%. In summary, ANP is managed primarily by a conservative therapy. In case of infected necrosis, interventional and minimally invasive approaches are the therapy of choice. Open surgery should be considered for patients deteriorating despite other measures and should be postponed as long as possible.
