[Nutritional therapy in acute pancreatitis].

In this review, systematic search of literatures for acute pancreatitis and nutrition was performed. Eleven randomized controlled trials (RCT) were found. Eight of them are about parenteral or enteral nutrition, 2 are about immunomodulated nutrition, and one is nutritional method in postoperative period. None of these showed benefit of total parenteral nutrition. Moreover, enteral nutrition via nasojejunal tube after 1-2 days after onset or operation of acute pancreatitis showed safe and more effectiveness than parenteral nutrition even in severe cases. These results indicate no benefit of parenteral nutrition in mild to moderate pancreatitis. Early enteral nutrition via nasojejunal tube can be used even in severe cases without ileus or intestinal ischemia.
