  1. Nutrition Therapy in Acute Pancreatitis Gila Greenbaum, Dietetic Intern, Sodexo 2014

  2. RBMC Guidelines • There are currently no guidelines in place at the facility for nutrition therapy in AP • This research can help create standards of care

  3. Objectives • Define acute pancreatitis (AP) • Differentiate between mild vs. severe AP (SAP) • Review research to determine recommended nutrition therapy (NT) for AP: I. Timing: when to initiate feedingsII. Diet: how to initiate feedings III. Enteral vs. Parenteral Nutrition • Review current guidelines: ACG, ASPEN, ESPEN

  4. What would you do? A patient is admitted with acute pancreatitis. After 24 hours, her amylase and lipase remain slightly elevated, but she no longer has abdominal pain or n/v. Would you initiate a diet or keep her NPO status? If you will start a diet, what diet would it be? Why? http://www.connecttoresearch.org/publications/2

  5. What is AP? • Inflammatory disorder • Digestive enzymes damage the pancreas • Primary causes: alcohol abuse, gallstones

  6. Mild vs. Severe AP

  7. How to diagnose mild vs. severe AP? • Ranson’s Criteria: Clinical signs ≥3 associated with severe course • Acute Physiology and Chronic Health Evaluation (APACHE) II: physiologic measurements, age, PMH ≥ 8 associated with severe course • CT Severity Index (CTSI): based on extent of inflammation/complications on scan

  8. Goal of Nutrition Therapy in AP • Reduce burden of disease • Maintain positive nitrogen balance without over-stimulating pancreatic fluids • Dietary improvement and/or advancement

  9. What have we done in the past? • Prolonged fasting/NPO until normalization of enzymes, resolution of pain & inflammation • Oral feedings initiated with clear liquid diet • If oral feeding not possible: TPN

  10. What is the recommended NT in AP? • Let’s see what the current research has to say……. • Timing: when to initiate feedings • Diet: how to initiate feedings • Enteral Nutrition (EN) vs. Parenteral Nutrition (PN)

  11. I. Timing: when to initiate feedings • 4 studies reviewed in this section: • Eckerwall, Clinical Nutrition, 2007 • Chebli, Journal of Gastroenterology and Hepatology2005 • Baker, currently ongoing • Hegazi, JPEN, 2011

  12. 1) Eckerwall, 2007 • Immediate feeding vs. traditional fasting • Methods: 60 patients, randomized to fasting or immediate oral feeding group • Findings: (1) No differences between groups concerning pancreatic enzyme levels, pain or GI symptoms(2) LOH shorter in the oral feeding group (4 vs. 6 days)

  13. 2) Chebli, 2005 • Early oral refeeding may stimulate pancreatic secretion, increase inflammation, cause relapse of abdominal pain • Pain relapse during oral refeeding relatively high on day 1-2 since admission • Pain relapse increased hospital stay and overall costs on disease treatment

  14. 3) Baker, ongoing • Does starting EN within 24 hrs reduce infections compared to starting EN and/or oral diet 3-4 days after admission? • 208 patients randomized: EN within 24 hours (group A), or oral diet plus EN 72 hours (group B) • Group A: started at 20ml/hr, with goal rate 65ml/hr within 72 hrs • Group B: NPO for 72 hrs, then oral diet and/or EN

  15. 4) Hegazi, 2011 • Investigated early initiation DJF • Retrospective chart analysis • Nutrition Intervention: 20-25kcal/kg (IBW), 1.5g/kg protein via DJT • Results: (1) Early initiation: reduced mortality, fewer complications (2) Early achievement of feeding goal rate: shorter LOS (9d vs. 19d)

  16. --- Recap on Timing --- • Most studies: feeding can be initiated within 24-48 hrs American College of Gastroenterology (ACG) Guidelines (2013) • Timing to initiate feedings remains controversial • Feedings can be started when there is no n/v, and abdominal pain has resolved • Mean time between hospital admission and 1st meal: 1.5 days

  17. II. Diet: how to initiate feedings • 2 studies reviewed in this section: • Sathiaraj,Aliment PharmacolTher, 2008 • Jacobsen,Clinical Gastroenterologyand Hepatology, 2007

  18. 1) Sathiaraj, 2008 • Tolerance of soft diet (SD) vs. clear liquid diet (CLD) in feeding initiation • Methods: 101 patients randomized to CLD (458kcal/d, 11g fat/d) or SD (1040kcal/d, 20g fat/d) • Findings: SD patients had decreased LOH post feeding (4 vs. 6d), reduced total LOHS (5 vs. 8d), no differences in pain

  19. 2) Jacobsen, 2007 • Low fat solid diet (LFSD) vs. CLD • Patients fed within 1-3 days post admission • Results: (1) LFSD was well tolerated, (2) Did NOT result in shorter LOH • Significance: LFSD can be considered for patients who desire greater dietary choice when initiating feeding after mild AP

  20. --- Recap on Diet --- • SD and LF solid diet are tolerated compared with CLD ACG Guidelines (2013): • Appropriate diet when initiating feedings: low fat low residue (soft) diet

  21. III. Enteral vs. Parenteral Nutrition • 1 study reviewed in this section: • Hegazi, J Parenter Enteral Nutr, 2011

  22. Nutrition Support

  23. New Research: EN vs. PN • EN: Encourages gut function, reduces bacterial overgrowth, fewer overall infections and complications • EN vs. PN: 1. 4.1 fewer days of nutritional support 2. Progressed to full oral feeding 1 day earlier • Cost savings: PN ($3294/pt) vs. EN ($761/pt)

  24. Hegazi, 2011 • PN offers nutrients without pancreatic stimulation • PN associated with infections, metabolic complications • Pancreatic stimulation minimized during EN using mid to distal jejunum (40-60cm distal to the ligament of Treitz) http://www.normanallan.com/Misc/mingmen.htm

  25. --- Recap on Enteral vs. Parenteral --- • Most research: EN has eclipsed PN as the new "gold standard" of NT in AP ACG Guidelines (2013) • PN should be avoided in SAP unless EN not possible (e.g. paralytic ileus) or tolerated

  26. ESPEN Guidelines • EN has no positive impact on mild AP, only recommended for patients NPO > 5 days • EN is recommended for SAP • Only supplement with PN if needed • EN should be continuous, peptide-based formula

  27. ASPEN Guidelines • Energy Requirements: Calories: 25–35 kcal/kg/d Protein: 1.2–1.5 g/kg/d • Mild-moderate AP: 1. NPO, gradual advancement to oral diet within 3-4d 2. Only consider nutrition support if NPO > 5d • EN: preferred over PN, initiate first if feasible • EN Formula: small peptide-based MCT, continuous feeding • PN used only if EN not tolerated/indicated

  28. Summary • Timing: remains controversial, within 24-48 hours, with no n/v or abdominal pain • Diet: low fat low residue diet (usually with mild to moderate AP) • EN preferred over PN when possible (usually with SAP)

  29. Back to the case study……. A patient is admitted with acute pancreatitis. After 24 hours, her amylase and lipase remain slightly elevated, but she no longer has abdominal pain or n/v. Would you initiate a diet or keep her NPO status? If you will start a diet, what diet would it be? Based on the current research and guidelines, is your answer different from your initial answer?
