Abstract

ABSTRACT

About 20% of acute pancreatitis cases develop necrosis and have a high risk of inflammatory and infectious complications and a high mortality rate. Acute pancreatitis has a variety of causes and despite years of research its pathogenesis remains complex and obscure. Both local and systemic inflammatory responses play key roles in the pathophysiology of this disorder. Treatment plans continue to rely on supportive care without proven specific therapies. Pancreatic rest and use of total parenteral nutrition (TPN) were the gold standard for nutritional support of these challenging patients. Because numerous studies in other critically ill patients demonstrated benefits of enteral nutrition, recent investigations compared TPN to enteral nutrition in acute pancreatitis. These studies indicated that enteral nutrition delivered into the jejunum was tolerated well, even in patients with severe acute pancreatitis. ``Mild'' cases of pancreatitis should improve and tolerate oral nutrition within a few days. In contrast, ``severe'' cases of pancreatitis or those with a protracted clinical course require nutritional support to aid in preventing adverse effects of starvation and nutrient deficiencies. Current recommendations are to attempt enteral nutrition in patients with acute pancreatitis prior to instituting TPN. Further studies to determine optimal nutrient composition are warranted and should investigate the possibility of modulating the inflammatory response induced by pancreatitis to improve outcomes.
