急性胰腺炎并发的感染通常可加重胰腺损伤导致的全身炎症反应综合征（SIRS）和多器官功能障碍综合征（MODS）,即被称为原发疾病得到控制后的“二次打击”效应。此报告分析了肠道内相关因素对急性胰腺炎感染形成的作用,指出肠道内细菌的易位（BT）和过度生长造成的肠道外继发感染是触发MODS的主要原因,并初步探讨了防治细菌易位的措施在急性胰腺炎治疗中的应用价值。 Infection with acute pancreatitis usually aggravates systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS) due to pancreatic injury, a “second strike” effect after controlled primary disease is controlled. This report analyzes the role of relevant factors in the intestinal tract in the formation of acute pancreatitis infection. It is pointed out that bacterial translocation (BT) in the intestine and secondary extraintestinal infection caused by overgrowth are the main causes of MODS. The application of translocation measures in the treatment of acute pancreatitis.
