Acute pancreatitis (AP) is a common clinical acute abdominal disease, which can be divided into three types:mild, moderate and severe. Severe acute pancreatitis still has a high mortality rate, but there is no specific drug for this disease, and non-operative symptomatic supportive treatment is the main therapy in the early stage of the disease. In recent years, a large number of clinical studies have shown that traditional Chinese medicine has a unique advantage in prevention and treatment of AP. According to the characteristics of the disease, such as abdominal pain, no stool, treatment based on syndrome differentiation can alleviate a series of symptoms, especially the formulations of "removing stasis by purgation" represented by Da Chengqitang, including the formula evolved based on Da Chengqitang. Specifically, Chaishao Chengqitang and Chaiqin Chengqitang can improve intestinal function, alleviate gastrointestinal symptoms, such as intestinal paralysis combined with AP patients, prevent intestinal flora ectopia, protect intestinal mucosal barrier function, and help activate enteral nutrition in early stage, regulate immune inflammatory response, so as to avoid systemic inflammatory response syndrome. In addition, categorized formulas Da Chengqitang can also promote pancreatic microcirculation, promote the recovery of damaged parts of pancreas during AP pathogenesis, reduce blood amylase, and improve systemic coagulation function and treatment effect. In China, integrated traditional Chinese and Western medicine treatment has become an important part of the treatment of AP at present. It can prevent AP from aggravating, reduce complications and shorten hospitalization time. To summarize the therapeutic effect of Da Chengqitang and its categorized formulas on AP in clinic, the authors review clinical studies of categorized formulas Da Chengqitang on AP in recent five years based on "intestinal function, intestinal nutrition, inflammatory mediators and pancreatic microcirculation".
