In the past century, the diagnosis and treatment of severe acute pancreatitis has repeatedly fluctuated between surgery and internal medicine. Through the joint efforts of many disciplines, a great breakthrough has been made. Initial fluid resuscitation, nutritional support, and prevention of pancreatitis related complications are currently the best treatment methods. Local complications may occur in patients with severe acute pancreatitis, including pancreatic pseudocysts and walled-off necrosis. Infected pancreatic necrosis is a fearful complication of severe acute pancreatitis. There has been a consensus on the " step-up" approach for the treatment of infected pancreatic necrosis, that is, percutaneous catheter drainage should be used first, and further surgical or endoscopic minimally invasive treatment should be taken for patients with poor drainage. And open surgery is no longer the preferred means of intervention. This article summarizes the progress of diagnosis and treatment of severe acute pancreatitis at home and abroad and shares the experience of the author's team in the diagnosis and treatment of severe acute pancreatitis.
