SAP runs a biphasic course. During the first 1-2 wk,a pro-inflammatory response results in systemic inflammatory response syndrome(SIRS). If the SIRS is severe,it can lead to early multisystem organ failure(MOF). After the first 1-2 wk,a transition from a pro-inflammatory response to an anti-inflammatory response occurs;during this transition,the patient is at risk for intestinal flora translocation and the development of secondary infection of the necrotic tissue,which can result in sepsis and late MOF. Many recommendations have been made regarding SAP management and its complications. However,despite the reduction in overall mortality in the last decade,SAP is still associated with high mortality. In the majority of cases,sterile necrosis should be managed conservatively,whereas in infected necrotizing pancreatitis,the infected non-vital solid tissue should be removed to control the sepsis. Intervention should be delayed for as long as possible to allow better demarcation and liquefaction of the necrosis. Currently,the step-up approach(delay,drain,and debride) may be considered as the reference standard intervention for this disorder.展开更多
