8 IAP/APA consensus meeting 171 aanwezigen; 71x Noord-Amerika 54x Europa, 39x Azie/Oceanie, 7x Zuid-Amerika 38 recommendations 21 (55%): strong recommendation (door reviewers gescoord) 34 (89%): strong agreement (tijdens plenaire stemming)

9 Q28. What are the indications for intervention in necrotizing pancreatitis?

10 Q28. What are the indications for intervention in necrotizing pancreatitis? Q28-A. Recommendation (1/2): Common indications: 1. Clinical suspicion of or documented infected necrotizing pancreatitis with clinical deterioration, preferably when the collection with necrosis has become walled-off, a process that typically takes 4 weeks. 2. Ongoing organ failure for several weeks after the onset of acute pancreatitis, preferably when the collection with necrosis has become walled-off, a process that typically takes 4 weeks. GRADE: 1C Recommendation: strong = grade 1/ weak=grade 2 Based on evidence: high=grade A/moderate=grade B /low=grade C

11 Q28. What are the indications for intervention in necrotizing pancreatitis? Q28-A. Recommendation (2/2): Less common indications: 3. Abdominal compartment syndrome 4. Acute bleeding 5. Bowel ischemia with/without perforation. 6. Gastric outlet obstruction with persisting / enlarging collection more than 4-8 weeks after onset of acute pancreatitis. 7. Pancreaticopleural fistula 8. Pancreatic ascites GRADE:1C Recommendation: strong = grade 1/ weak=grade 2 Based on evidence: high=grade A/moderate=grade B /low=grade C

12 Q29. What is the role of fine needle aspiration to diagnose infected necrosis?

13 Q29. What is the role of fine needle aspiration to diagnose infected necrosis? Q29-A. Recommendation: FNA can confirm infection in necrotizing pancreatitis but is not mandatory because clinical and imaging signs (gas in peripancreatic collections) are sufficient in the majority of cases. Fine needle aspiration can provide false-negative results. GRADE: 1C Recommendation: strong = grade 1/ weak=grade 2 Based on evidence: high=grade A/moderate=grade B /low=grade C

14 Q30. What are the indications for intervention in sterile necrotizing pancreatitis?

15 Q30. What are the indications for intervention in sterile necrotizing pancreatitis? Q30-A. Recommendation: 1. Ongoing gastric outlet or biliary obstruction due to mass effect of a large WOPN (arbitrarily > 4-8 weeks) 2. Persistent symptoms (e.g. pain, persistent unwellness ) in patients with large collection(s) with necrosis (arbitrarily >8 weeks) 3. Disconnected duct syndrome with persisting symptomatic (e.g. pain, obstruction) collection(s) (arbitrarily > 8 weeks) 4. Pancreaticopleural fistula 5. Pancreatic ascites 6. Obstructive jaundice GRADE: 2C Recommendation: strong = grade 1/ weak=grade 2 Based on evidence: high=grade A/moderate=grade B /low=grade C

16 Q30. What are the indications for intervention in sterile necrotizing pancreatitis? Q30-B.Remarks concerning the recommendation: Less than 1% of patients with necrotizing pancreatitis will have symptoms of obstruction necessitating intervention. Data is lacking on the proportion of patients that will require intervention in the months after an episode of necrotizing pancreatitis. Data is lacking on the optimal timing of intervention
