[Pancreatic necrosis: pro surgical therapy].

Currently, patients with severe necrotizing pancreatitis rarely need interventional or surgical treatment. However, in case of pancreatic infection and septic complications they should be treated with the step up approach, primarily with an interventional or endoscopic drainage. If further clinical deterioration occurs necrosectomy is indicated. This should ideally be postponed until the third or fourth week after onset of pancreatitis to optimize surgical conditions including demarcation of the necrosis. Open necrosectomy with postoperative continuous lavage is a valid treatment option with low mortality, low morbidity and good long-term outcome. In recent years, several minimally invasive techniques for necrosectomy have been developed and are alternative approaches in about 70% of cases. In most cases, the retroperitoneoscopic approach is used, although the endoscopic transgastric route is also being used more and more frequently. While the reduced operative trauma should theoretically also reduce the onset of postoperative organ failure, no study has actually proven this.
