What are the causes and symptoms of acute pancreatitis?

From the Guidelines

Acute pancreatitis requires prompt medical attention with a focus on aggressive fluid resuscitation, pain management, and nutritional support to prevent complications and improve outcomes. The management of acute pancreatitis involves hospitalization for pain management, intravenous fluids, and bowel rest. Pain control is achieved with medications like morphine (2-4mg IV every 4 hours) or hydromorphone (0.5-1mg IV every 4 hours) 1. Aggressive IV fluid resuscitation with lactated Ringer's solution at 5-10 mL/kg/hr for the first 24 hours is crucial to prevent complications.

Key aspects of management include:

• Enteral nutrition (oral, NG, or NJ) is recommended, with parenteral nutrition considered if enteral nutrition is not tolerated 1
• Early fluid resuscitation and mechanical ventilation may be necessary in severe cases
• Prophylactic antibiotics are not recommended for all patients with acute pancreatitis, but antibiotics should be used to treat infected severe acute pancreatitis 1
• Diagnosis of infected severe acute pancreatitis can be challenging and may require procalcitonin (PCT) levels, CT- or EUS-guided fine-needle aspiration (FNA) for Gram stain and culture, or endoscopic retrograde cholangiopancreatography (ERCP) in patients with acute biliary pancreatitis and common bile duct obstruction 1

The underlying cause of acute pancreatitis, commonly gallstones or alcohol, must be identified and addressed. Gallstone pancreatitis may require ERCP within 24-48 hours if there's evidence of biliary obstruction. Acute pancreatitis can be life-threatening due to potential complications like necrosis, pseudocysts, or multi-organ failure, making early diagnosis and aggressive supportive care essential for recovery, as highlighted in recent guidelines 1.

From the Research

Overview of Acute Pancreatitis

• Acute pancreatitis is a common inflammatory disorder of the pancreas resulting in considerable morbidity and a mortality rate of approximately 5% 2
• The management of acute pancreatitis involves intravenous fluid resuscitation, which remains the cornerstone in the early treatment of acute pancreatitis 3

Fluid Resuscitation in Acute Pancreatitis

• Aggressive intravenous fluid resuscitation is generally recommended in all patients with acute pancreatitis 2
• However, several observational studies and small clinical trials have raised concern about the efficacy and safety of aggressive fluid resuscitation 3
• Lactated Ringer's solution is the preferred fluid type based on animal studies, clinical trials, and meta-analyses 3
• The optimal timing, fluid type, volume, rate, and duration of fluid resuscitation in acute pancreatitis are still unclear and require further investigation 3, 2

Comparison of Fluid Resuscitation Types

• A retrospective study found no significant difference in the distribution of acute pancreatitis severity between patients who received lactated Ringer's solution and those who received normal saline 4
• The study also found no significant differences between the two groups in terms of confirmed pancreatic necrosis, requirement for enteral nutrition, mortality, and duration of hospital stay 4

Use of Proton Pump Inhibitors in Acute Pancreatitis

• A nationwide cohort study found that the use of proton pump inhibitors in mild acute pancreatitis is associated with reduced pancreatitis-related complications and improved mortality 5
• The study suggests that proton pump inhibitors may have a potential anti-inflammatory effect and possible inhibition of pancreatic secretion, which could be beneficial in the management of acute pancreatitis 5

Need for Further Research

• Large, well-designed, multicenter randomized controlled trials are needed to determine the optimal timing, fluid type, volume, rate, and duration of fluid resuscitation in acute pancreatitis 3
• Prospective studies are needed to confirm the findings of the nationwide cohort study on the use of proton pump inhibitors in acute pancreatitis 5
