Abstract: Acute pancreatitis is a digestive emergency. According to the modified Atlanta classification criteria, acute pancreatitis is classified into three types: mild, moderate to severe and severe, in which the severe acute pancreatitis has a higher mortality rate. Early acute fluid and necrotic accumulation, later encapsulated fluid and necrotic accumulation, and infectious pancreatic necrosis are common local complications of severe acute pancreatitis. Abdominal drainage is an important component of treatment, but its timing and method of drainage are still controversial in clinical practice. The abdominal drainage treatment for severe acute pancreatitis includes timely drainage of abdominal fluid during the acute phase and puncture drainage for infectious pancreatic necrosis. The author delves into the timing and drainage plan of abdominal puncture drainage, summarizes current literature, guidelines, and clinical practice experience, and proposes the necessity of developing personalized puncture drainage plans for different patients.
