Study Notes

Acute Pancreatitis Treatment Strategies

  • Acute pancreatitis (AP) is a leading cause of gastrointestinal-related hospitalizations globally, with incidence increasing
  • Initial management within the first 72 hours is crucial for impacting clinical outcomes
  • Key initial management components include: assessing severity, fluid resuscitation, pain control, nutrition support and antibiotic use (ERCP in gallstones)
  • Updated fluid resuscitation strategies emphasize non-aggressive, goal-directed approaches with lactated Ringer's solution instead of normal saline
  • Early enteral feeding is beneficial
  • Prophylactic antibiotic use is often limited, with procalcitonin-based algorithms used for appropriate assessment of inflammation vs infection
  • Urgent ERCP is recommended for gallstone pancreatitis and cholangitis but not in the absence of cholangitis

Initial Management (First 72 hours)

  • AP severity is crucial for predicting prognosis and guiding management (Revised Atlanta Classification)
  • Persistent organ failure for >48 hours indicates severe AP (mortality rate up to 43%)
  • Many prognostic models exist but no single model consistently superior in significant comparisons during early disease course (accuracy around 80%)
  • Systemic Inflammatory Response Syndrome (SIRS) and Bedside Index of Severity of Acute Pancreatitis (BISAP) score are relevant validated tools

Fluid Resuscitation

  • Aggressive hydration is traditionally used. However, overtreatment is detrimental in severe AP
  • Goal-directed therapy (GDT) aims to address specific physiological targets, such as heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP), urine output (UO), central venous oxygen saturation (ScvO2), blood urea nitrogen (BUN), hematocrit, and lactate levels
  • GDT was not found to significantly improve outcomes but it provides a structured, physiological-targeted approach, especially in severe cases. However, careful monitoring and frequent assessment, at 2-3 hour intervals is paramount
  • Appropriate fluid type and volume depend on patient parameters; in mild cases, oral feeding can be initiated 12 hours after symptom onset

Fluid Type

  • Isotonic crystalloid solutions (normal saline, lactated Ringer's, Plasma-Lyte, Hartmann's) are generally favored in AP
  • Balanced crystalloids (lactated Ringer's) are increasingly preferred over normal saline due to potential adverse effects (hyperchloremic non-anion gap acidosis, acute kidney injury)
  • Results from recent RCTs indicate the potential advantage of balanced crystalloids.

Pain Control

  • Opioids are effective but caution is recommended due to potential complications (respiratory depression, constipation, and dependence)
  • NSAIDs and acetaminophen are alternative options and can be equally effective in moderate cases, with caution in patients with renal impairment, gastric ulcers, or bleeding risks

Nutritional Support

  • Early enteral feeding (within 24-48 hours) is now preferred over parenteral nutrition in most cases to reduce hospital stays, complications, and improve patient outcomes.
  • For patients intolerant of oral feeding within 72h, an enteral tube may be necessary

Prophylactic Antibiotic Use

  • Procalcitonin-guided antibiotic use is preferred

Cholecystectomy

  • Prophylactic cholecystectomy is recommended during initial hospital admission for AP cases involving gallstones.
  • Same-admission cholecystectomy ( within 7 days ) is often more effective than delayed cholecystectomy, especially in case of mild AP

Lipid-Lowering Medications

  • These are crucial in hypertriglyceridemia-induced acute pancreatitis (HTG-AP), focusing on early elimination of triglycerides.

Alcohol Intervention

  • Alcohol abstinence is important in alcoholic pancreatitis to prevent recurrence.
