IS NUTRITION SO IMPORTANT?
MILD AP• Little influence on nutritional
status and metabolism
SEVERE AP
• Increased energy expenditure
• Hypermetabolism
• Protein catabolism (negative
nitrogen balance up to 40 g/day)
• Malnutrition

MILD AP
• No need for enteral nutrition
• Normal food after 5 – 7 days
• If oral food not tolerated – intrajejunal supply after 5 days
ESPEN GUIDELINES 2006.
SEVERE AP
• Early enteral nutrition if feasible
• Parenteral nutrition supplement if needed
• Oral food intake as soon as possible

Neither the supplementation of enteral nutrition withprobiotics nor the use of immunonutrition significantlyimproves the clinical outcomes.
STUDY CONCLUSIONS
The use of polymeric vs. (semi)elemental formulation
leads to no significantly higher risk of feeding intolerance,
infectious complications or death.

• Antibiotic prophylaxis meta-analyses limitations:– Primary study design limitations (inclusion criteria, antibiotic
duration and dosing, nutritional support, resuscitative measures)
– Relatively small number of patients
– Different outcome measurements
– Inclusion of nonblinded studies
• Additional, well-carried out studies are needed!(especially regarding adverse effects, duration of therapy and impact of etiology on infection outcome)

Most devastating

Account for almost 80% of all deaths

Early surgery (within 48 h) in gallstone pancreatitis –
higher mortality
Discharged patients with gallstone pancreatitis –
reccurence up to 63%(Uhl, Pancreatology 2002;2:565-573
Need for surgery - IPN proven by FNA (when septic
complications develop)
Early <14 days after onset > late surgery ?

SURGICAL DECOMPRESSION OF IAH
in patients with severe AP
De Waele JJ, Leppäniemi AK. World J Surg 2009; 33:1128-1133
Does it work
• IAP significantly lowered
Does it help
• controversial data
• mortality is higher in patients with:
• preoperative renal failure
• lower preoperative IAP
• late decompression (after 7 days)

SURGICAL DECOMPRESSION OF IAH
in patients with severe AP
Is it safe ???
• retroperitoneal hemorrhage
• prolonged course
• multiple reoperations
• high risk of complications
De Waele JJ, Leppäniemi AK. World J Surg 2009; 33:1128-1133
• subcutaneous fasciotomy – safest
