AbstractSeptic complications are an important factor for the morbidity and mortality of acute pancreatitis. The gut has been identified as a source of infection early in the course of the disease allowing intestinal bacteria to translocate into pancreatic necrosis and other organs. Bacterial translocation is promoted by an impaired intestinal mucosal barrier which can be attributed to the reduced oxygen and substrate supply of the intestine during the early systemic response to the pancreatic injury. A rat model of severe acute pancreatitis has been used to confirm the hypothesis that an impaired mucosal barrier can be stabilized by supplying certain nutritients, vitamins and trace elements. Following a discussion of the many aspects of bacterial translocation and gut derived sepsis, the role of the gut and nutrition for the development of septic complications in acute pancreatitis is summarized as follows: Early in the course of acute pancreatitis the gut is a target organ of the primary systemic inflammatory response (SIRS) to pancreatic injury. SIRS-induced gut barrier dysfunction promoting bacterial translocation makes the gut the motor for secondary (septic) complications. As a septic focus the gut becomes a target for therapeutic measures aimed at stabilizing the impaired gut barrier. Nutritive factors demonstrated to improve impaired gut barrier function include early enteral feeding and specific factors like glutamine which are essential for enterocytes and colonocytes in stress. Experimental data are presented to underline the significance of these nutritive factors and subsequent randomized multicenter trials performed to verify the positive experimental results are introduced. The effect of other nutritive factors (e.g. omega-3-fatty acids) has not yet been systemically investigated. Thus, experimental and clinical studies need to be performed for evaluating their effect on bacterial translocation and the disease course in acute pancreatitis.
