Nutrition support during acute pancreatitis

Area of Science:

• Gastroenterology
• Clinical Nutrition
• Metabolic Disorders

Background:

• Acute pancreatitis significantly increases protein catabolism (80%) and energy expenditure (20%), elevating nutritional needs.
• Negative nitrogen balance resolution via nutrition support correlates with improved outcomes in acute pancreatitis.
• Historically, total parenteral nutrition (TPN) and bowel rest were favored due to concerns that feeding might worsen pancreatic autolysis.

Purpose of the Study:

• To evaluate jejunal feeding as an alternative to TPN in managing nutritional requirements for acute pancreatitis.
• To compare the safety and efficacy of jejunal feeding versus TPN in patients with acute pancreatitis.

Main Methods:

• Review of controlled trials comparing TPN with jejunal feeding in acute pancreatitis.
• Analysis of physiologic studies on nutrient infusion into the distal jejunum to bypass pancreatic stimulation.

Main Results:

• Jejunal feeding has not been shown to exacerbate acute pancreatitis in any study.
• Jejunal feeding is associated with a lower incidence of infectious and metabolic complications compared to TPN.
• Enteral jejunal feeding is significantly more cost-effective than TPN (one-tenth the cost).

Conclusions:

• Jejunal feeding is a safe and effective method for nutritional support in acute pancreatitis.
• Jejunal feeding offers advantages over TPN, including fewer complications and lower costs.
• Jejunal feeding is now generally accepted as the preferred nutritional management strategy for acute pancreatitis.
