Management of Pancreatitis Complications

Initial Assessment and Monitoring

• The British Society of Gastroenterology recommends that all patients with pancreatitis require ongoing reassessment on a daily or more frequent basis to diagnose life-threatening complications early 1
• Clinical monitoring should include assessment for prolonged ileus, abdominal distension, tenderness, epigastric mass, vomiting, and signs of sepsis 2
• Laboratory monitoring should include leucocyte and platelet counts, clotting studies, APACHE II score, and CRP concentration to detect possible sepsis 3
• The American College of Gastroenterology recommends oxygen saturation should be measured continuously with supplemental oxygen administered to maintain arterial saturation greater than 95% 4

Fluid Resuscitation

• The British Society of Gastroenterology recommends non-aggressive fluid resuscitation at a rate of 1.5 ml/kg/hr following an initial bolus of 10 ml/kg, with Lactated Ringer's solution preferred 5
• Total crystalloid fluid administration should be less than 4000 ml in the first 24 hours to avoid fluid overload 5
• Fluids should be given intravenously to maintain urine output >0.5 ml/kg body weight 6
• The rate of fluid replacement should be monitored by frequent measurement of central venous pressure in appropriate patients 6

Imaging for Complications

• Dynamic CT should be performed within 3-10 days of admission in severe cases to assess the extent of pancreatic necrosis 4
• CT severity index combines CT grade and necrosis score to predict complications and mortality 6
• Follow-up CT scans are recommended only if the patient's clinical status deteriorates or fails to show continued improvement 6
• Ultrasound is helpful in the evaluation and serial monitoring of fluid collections 3

Management of Specific Complications

• The American College of Gastroenterology recommends that all patients with persistent symptoms and >30% pancreatic necrosis, or smaller areas with clinical suspicion of sepsis, should undergo image-guided fine needle aspiration 7
• Patients with infected necrosis require intervention to completely debride all cavities containing necrotic material 7
• The choice of surgical technique for necrosectomy depends on individual features and locally available expertise 7

Antibiotic Management

• The evidence regarding antibiotic prophylaxis against infection of pancreatic necrosis is conflicting 7
• If antibiotic prophylaxis is used, it should be given for a maximum of 14 days 7

Referral to Specialist Centers

• Management in, or referral to, a specialist unit is necessary for patients with extensive necrotizing pancreatitis or with other complications 7
• Every hospital that receives acute admissions should have a single nominated clinical team to manage all patients with acute pancreatitis 7
