Integrated traditional Chinese and Western medicine has been used to treat acute pancreatitis (AP) for more than 50 years. It has become a dominant and specialized disease treated by integrated traditional Chinese and Western medicine. After many years of clinical practice, a relatively mature and complete treatment system has been formed. Therefore, it was proposed by the Chinese Society of Integrated Traditional Chinese and Western Medicine, the Chinese Medical Association, and the Chinese Association of Traditional Chinese Medicine to update and formulate the “Guidelines for the Diagnosis and Treatment of Acute Pancreatitis with Integrated Traditional Chinese and Western Medicine” (2021) group standards in 2022, and “Integrated Traditional Chinese and Western Medicine Practice Guidelines for Diagnosis and Treatment of Acute Pancreatitis” finally published. The guideline condenses 25 kinds of important clinical issues, which guide to explain the diagnosis and treatment of AP in detail, focusing on the integration of traditional Chinese medicine and Western medicine in the management of AP, such as staging and syndrome differentiation, early fluid therapy, pain management, and organ function support in early stage. The advantages and the timing of early intervention of traditional Chinese medicine in AP are emphasized. This guideline also proposes suggestions on nutritional support, management of causes, treatment of late local complications and infections, as well as prevention of recurrence and follow-up strategies for long-term complications. This paper provides an interpretation of this guideline.
