Acute pancreatitis (AP) is associated with a catabolic and hypermetabolic state. Approximately 20% of AP cases are severe, manifesting as the systemic inflammatory response syndrome (SIRS) associated with multiorgan dysfunction (MOD) and a 15% to 40% mortality . Nutrition support is critical in severe acute pancreatitis (SAP). Early enteral nutrition is safe and beneficial in SAP and its use is linked to better glycemic control, reduced infectious complications, and reduced multiorgan failure and mortality. Enteral nutrition may be provided by the gastric or jejunal route in patients with SAP. The placement of feeding tube and route selection is the key to the implementation of enteral nutrition.
