Nutritional support in acute pancreatitis.Curr Opin Clin Nutr Metab Care. 2008 May; 11(3):261-6.CO
PURPOSE OF REVIEW
This review explores the role of enteral and parenteral nutrition in severe acute pancreatitis and discusses the potential benefits of glutamine, omega-3 fatty acids, arginine and selenium together with probiotics and prebiotics in these patients. In addition, the method of refeeding during the convalescent period is also examined.
A complex picture is emerging in which enteral nutritional support may be important early in the course of the disease with parenteral nutrition being used more as a backup and possibly only after the systemic inflammatory response has peaked. Nasogastric feeding, sometimes supplemented by parenteral nutrition, is as efficacious as nasojejunal feeding. An individualized approach, in which strategies of nutritional support are tailored to patient response, is gaining currency. Data regarding specialized formulae are mixed but the use of prebiotics is showing promise and is worthy of further exploration. In the convalescent period, preliminary data also indicate that the risk of pain developing is no greater if a light diet is instituted rather than clear fluids.
Nutritional support in acute pancreatitis remains challenging and controversial with a number of different and unexpected approaches, including the use of nasogastric feeding and dual enteral and parenteral nutrition support, being adopted in recent clinical trials.
