[Necrosectomy or anatomically guided resection in acute pancreatitis]

Area of Science:

• Gastroenterology
• Surgical Gastroenterology
• Critical Care Medicine

Context:

• Necrotizing pancreatitis presents significant morbidity and mortality.
• Historically, early and extensive pancreatic resection was the standard surgical approach.
• Advances in critical care and understanding disease pathogenesis have evolved treatment strategies.

Purpose:

• To review the current standards of care for necrotizing pancreatitis.
• To delineate the indications for conservative versus surgical management.
• To evaluate surgical techniques for pancreatic necrosis.

Summary:

• Conservative management is now the initial standard for necrotizing pancreatitis, effectively treating sterile necrosis with low morbidity and mortality.
• Surgical intervention is indicated for infected necrosis or sterile necrosis with persistent multiorgan failure despite intensive care.
• Pancreatic resection is discouraged; current surgical standards involve digital necrosectomy followed by drainage, open lavage, or closed lavage, yielding comparable outcomes.

Impact:

• This shift optimizes patient outcomes by reserving invasive procedures for specific indications.
• Minimally invasive necrosectomy techniques improve morbidity, mortality, and long-term results compared to resection.
• Updated treatment guidelines enhance the management of severe pancreatitis.
