[Acute pancreatitis--conservative versus surgical therapy]

Area of Science:

• Gastroenterology and Hepatology
• Critical Care Medicine
• Surgical Gastroenterology

Context:

• Acute necrotizing pancreatitis presents significant mortality risks due to potential multiorgan failure (MOF) and systemic inflammatory response syndrome (SIRS).
• Historically, MOF/SIRS in necrotizing pancreatitis often indicated surgical intervention, carrying substantial risks.
• Advancements in critical care, including continuous veno-venous hemofiltration (CVVH), offer new therapeutic avenues.

Purpose:

• To evaluate the current therapeutic strategies for acute necrotizing pancreatitis, focusing on the role of surgery versus conservative management.
• To assess the efficacy of continuous veno-venous hemofiltration (CVVH) in managing MOF/SIRS associated with necrotizing pancreatitis.
• To redefine surgical indications in acute necrotizing pancreatitis based on evidence of infected necrosis or specific complications.

Summary:

• Systemic inflammatory response syndrome (SIRS) and multiorgan failure (MOF) in acute necrotizing pancreatitis are not absolute indications for surgery if pancreatic necrosis is uninfected.
• Successful conservative management of severe necrotizing pancreatitis is increasingly feasible with growing experience in continuous veno-venous hemofiltration (CVVH).
• Surgical intervention is reserved for cases with documented infected pancreatic necrosis, massive bleeding, or bowel perforation due to tryptic lesions.

Impact:

• This approach shifts the paradigm for managing necrotizing pancreatitis, prioritizing less invasive strategies when possible.
• Early implementation of CVVH can improve outcomes for patients with MOF/SIRS, potentially reducing mortality.
• Clearer surgical criteria enhance patient selection and optimize resource allocation in critical care settings.
