Management of Acute Pancreatitis

Severity-Based Management Approach

• The American Gastroenterological Association recommends that all patients with severe acute pancreatitis must be managed in a high dependency unit or intensive care unit with full monitoring and systems support, while mild cases can be managed on a general ward 1, 2, 3
• Patients with mild pancreatitis can be managed on a general ward with basic vital sign monitoring and peripheral venous access for fluid administration 2, 3, 4
• Continuous oxygen saturation monitoring with supplemental oxygen to maintain >95% is recommended for patients with mild pancreatitis 3, 4

Fluid Resuscitation

• The American College of Gastroenterology recommends goal-directed moderate fluid resuscitation with Lactated Ringer's solution rather than aggressive fluid resuscitation 2, 3
• Target urine output >0.5 ml/kg body weight is recommended for patients with acute pancreatitis 2
• Monitoring of hematocrit, blood urea nitrogen, creatinine, and lactate is recommended to assess tissue perfusion 2

Nutritional Management

• The American Gastroenterological Association recommends initiating oral feeding immediately rather than keeping patients NPO 2
• Regular diet can be advanced as tolerated with appropriate pain management 3
• Enteral nutrition via nasogastric or nasoenteral tube is recommended if oral feeding is not tolerated 2, 3

Pain Management

• The American Pain Society recommends pain control as a clinical priority with Dilaudid preferred over morphine or fentanyl in non-intubated patients 2
• Consider epidural analgesia as an alternative or adjunct in a multimodal approach for severe cases 2

Antibiotic Therapy

• The Infectious Diseases Society of America recommends not using prophylactic antibiotics in mild acute pancreatitis or biliary pancreatitis 2, 3, 4
• Prophylactic antibiotics may be used in severe acute pancreatitis with evidence of pancreatic necrosis (>30%) 2
• Intravenous cefuroxime is a reasonable balance between efficacy and cost if antibiotics are used 5

Imaging

• The American College of Radiology recommends dynamic contrast-enhanced CT within 3-10 days in severe cases to identify pancreatic necrosis 2, 4
• Non-ionic contrast should be used in all cases 5
• Routine CT scanning is unnecessary in mild cases unless clinical deterioration occurs 2, 3, 4

Gallstone Pancreatitis Management

• The American Gastroenterological Association recommends urgent therapeutic ERCP within 72 hours in patients with severe gallstone pancreatitis, cholangitis, jaundice, or dilated common bile duct 1, 3, 4
• All patients undergoing early ERCP for severe gallstone pancreatitis require endoscopic sphincterotomy whether or not stones are found 1

Management of Pancreatic Necrosis

• The American Gastroenterological Association recommends image-guided fine needle aspiration 7-14 days after onset for patients with persistent symptoms and >30% pancreatic necrosis, or those with smaller areas and clinical suspicion of sepsis 1, 3
• Patients with infected necrosis require intervention to completely debride all cavities containing necrotic material 1, 2, 3
• Infected necrosis carries 40% mortality 2

Common Pitfalls to Avoid

• Routine use of antibiotics in mild pancreatitis is not recommended 3, 4
• Delaying ERCP in severe gallstone pancreatitis with cholangitis is not recommended 3, 4
• Failing to provide adequate nutritional support is not recommended 3, 4
• Overuse of CT scanning in mild cases with clinical improvement is not recommended 3, 4
• Using aggressive fluid resuscitation instead of goal-directed moderate resuscitation is not recommended 2, 3
• Keeping patients NPO when they can tolerate oral feeding is not recommended 2

Management of Acute Pancreatitis

Initial Severity Assessment and Triage

• The British Society of Gastroenterology recommends using clinical impression, obesity, APACHE II score in first 24 hours, C-reactive protein >150 mg/L, Glasgow score ≥3, or persisting organ failure after 48 hours to predict severity in patients with acute pancreatitis 6
• Severe acute pancreatitis requires management in HDU or ICU with full monitoring and systems support, as recommended by the British Society of Gastroenterology 7

Fluid Resuscitation Strategy

• No cited facts are available for this section

Nutritional Management

• The British Society of Gastroenterology suggests that enteral nutrition via nasogastric tube is effective in 80% of cases and is as effective as nasojejunal route in patients with acute pancreatitis 6

Antibiotic Strategy

• The British Society of Gastroenterology recommends considering prophylactic antibiotics only in severe acute pancreatitis with evidence of pancreatic necrosis >30% and limiting the duration to a maximum of 14 days 6, 7

Management of Gallstone Pancreatitis

• The British Society of Gastroenterology recommends performing urgent therapeutic ERCP within 72 hours in patients with severe gallstone pancreatitis, cholangitis, jaundice, or dilated common bile duct 6, 7
• All patients undergoing early ERCP for severe gallstone pancreatitis require endoscopic sphincterotomy whether or not stones are found in the bile duct, as recommended by the British Society of Gastroenterology 6, 7

Management of Pancreatic Necrosis

• The British Society of Gastroenterology recommends that patients with infected necrosis require intervention to completely debride all cavities containing necrotic material 6, 7

Referral Criteria

• The British Society of Gastroenterology suggests that management in, or referral to, a specialist unit is necessary for patients with extensive necrotizing pancreatitis or complications requiring ICU care, or interventional radiological, endoscopic, or surgical procedures 6, 7
