Treatment strategy for acute pancreatitis

Area of Science:

• Gastroenterology
• Critical Care Medicine
• Diagnostic Imaging

Background:

• Acute pancreatitis (AP) requires prompt medical intervention, including fluid resuscitation, analgesia, and vital sign monitoring.
• Severity assessment is critical for tailoring treatment and preventing complications, necessitating repeat evaluations due to the condition's instability.

Purpose of the Study:

• To outline the diagnostic and therapeutic strategies for acute pancreatitis, differentiating between mild and severe forms.
• To emphasize the importance of etiological investigation and timely interventions, such as ERCP/ES for biliary pancreatitis.
• To detail management approaches for both early and late stages of AP, including intensive care and management of infectious complications.

Main Methods:

• Initial management involves fasting, intravenous (IV) fluid replacement, analgesics, and vital sign monitoring.
• Severity is assessed using clinical signs, blood tests, urinalysis, and imaging.
• Etiology is investigated via blood tests, urinalysis, and diagnostic imaging.
• Endoscopic retrograde cholangiopancreatography with or without endoscopic sphincterotomy (ERCP/ES) is considered for biliary pancreatitis with cholangitis or stasis.
• Infectious complications are diagnosed using fine needle aspiration (FNA).

Main Results:

• Mild AP cases are managed with continued fundamental treatment until symptom resolution.
• Severe acute pancreatitis (SAP) requires referral to specialized centers for intensive care, focusing on hemodynamic stabilization, respiratory support, and antibiotics.
• Continuous hemodiafiltration (CHDF) and continuous regional arterial infusion (CRAI) may benefit early SAP.
• In late-stage AP, infectious complications are critical; FNA aids diagnosis.
• Treatment for infected pancreatic necrosis includes percutaneous, endoscopic, laparoscopic, or surgical approaches, with necrosectomy performed as late as possible.
• Pancreatic abscesses require drainage.

Conclusions:

• Prompt and accurate diagnosis, coupled with tailored treatment strategies based on severity and etiology, are essential for managing acute pancreatitis.
• Early and aggressive management of SAP, including intensive care and timely interventions for complications, improves outcomes.
• Distinguishing between sterile and infected necrosis guides therapeutic decisions, prioritizing less invasive methods when feasible and delaying necrosectomy when possible.
