title: Surgery in the treatment of acute pancreatitis--open pancreatic necrosectomy.
abstract: Management of acute necrotizing pancreatitis has changed significantly over the past years. Early management is non-surgically and solely supportive. Today, more patients survive the early phase of severe pancreatitis due to improvements of intensive-care-medicine. Pancreatic infection is the major risk factor with regard to morbidity and mortality in the late phase of severe acute pancreatitis. Whereas early surgery and surgery for sterile necrosis can only be recommended in selected cases, pancreatic infection is a well accepted indication for surgical treatment. Surgery should ideally be postponed until four weeks after the onset of symptoms as necrosis is well demarcated at that time. Four surgical techniques can be performed with comparable results regarding mortality: necrosectomy combined with (1) open packing, (2) planned staged relaparotomies with repeated lavage, (3) closed continuous lavage of the retroperitoneum, and (4) closed packing. However, closed continuous lavage of the retroperitoneum, and closed packing seem to be associated with a lower morbidity compared to the other two approaches. Advances in radiologic imaging, new developments of interventional radiology and other minimal access interventions have revolutionized the management of many surgical conditions over the past decades. However, minimal invasive surgery and interventional therapy for infected necrosis should be limited to specific indications in patients who are critically ill and otherwise unfit for conventional surgery. Open surgical debridement is the "gold standard" for treatment of infected pancreatic and peripancreatic necrosis.
