Nutritional management of acute pancreatitis

Abstract

Most patients with acute pancreatitis have mild to moderate disease and require no specialized nutritional support. Twenty percent to 30% have severe cases, resulting in a catabolic hypermetabolic state, and these patients may require early aggressive nutritional support. Traditionally, this support has been in the form of total parenteral nutrition. However, recent data suggest that enteral nutrition infused into the jejunum is feasible, well tolerated, associated with fewer complications, and significantly less expensive than parenteral nutrition. The pathophysiology of gut function in acute pancreatitis and the rationale and evidence for parenteral and enteral nutritional support are reviewed herein. An algorithm on the nutritional management of acute pancreatitis is suggested.
