Acute pancreatitis with an emphasis on infection.

Acute pancreatitis is an inflammatory disease that is mild and self-limiting in about 80% of cases. However, severe necrotizing disease still has a mortality of up to 30%. Differentiated multimodal treatment concepts are needed for these patients, including a multidisciplinary team (intensivists, gastroenterologists, interventional radiologists, and surgeons). The primary therapy is supportive. Patients with infected pancreatic necrosis who are septic undergo interventional or surgical treatment, ideally not before the fourth week after onset of symptoms. This article reviews the pathophysiologic mechanisms of acute pancreatitis and describes clinical pathways for diagnosis and management based on the current literature and guidelines.
