The treatment of severe pancreatitis requires care in an ICU, involving a multidisciplinary team. Early treatment of severe pancreatitis focuses on non-surgical management centered on organ function support, and sterile necrosis is preferably treated non-surgically. Surgical treatment is applied once necrotic infection occurs. Non-surgical treatment principally involves intensive care monitoring and mainly consists of fluid replacement, maintenance of electrolyte and acid-base balance, energy support, and prevention of local and systemic complications. Additionally, current non-surgical treatments for severe pancreatitis include bedside blood filtration, abdominal lavage, etc. Moreover, minimally invasive treatments are supplementary methods for managing severe pancreatitis, including biliary drainage, minimally invasive techniques, and treatment of infected pancreatic necrosis. Surgical intervention, involving the removal of necrotic tissue, is necessary during the infection phase.
