The peripancreatic infection is a severe complication during severe acute pancreatitis. Early diagnosis, effective prevention and timely treatment are directly associated to prognosis. In recent years, with the promotion and application of the concept of damage control and the rapid development of imaging intervention techniques, the treatment for peripancreatic infection has become "multi-step, step-up" minimally invasive surgical strategy from early laparotomy. The transformation of this concept and method has significantly improved the efficacy of peripancreatic infection in clinical practice. However, there are still many problems to be solved, such as prophylactic antibiotics, the choice of minimally invasive surgical techniques, and the management of early ascites. In addition, due to the variability and complexity of the course of severe acute pancreatitis, there is no uniform standard for clinical treatment and management of peripancreatic infection. Only through multidisciplinary collaboration, including surgery, imaging, nutrition and intensive care, can we truly achieve appropriate risk assessment, accurate clinical diagnosis and effective individualized treatment for these patients.
