The role of gut microbiota in the pathogenesis and treatment of acute pancreatitis: a narrative review.

To investigate the role played by gut microbiota in the development and treatment of acute pancreatitis. Gut microbiota is the largest micro-ecosystem in the human body, and is related to various system diseases. Acute pancreatitis is one of the common acute critical diseases in clinical practice, and there are various causative factors for the occurrence of this disease, such as alcohol, infection, obstruction and intestinal microecological factors. The dysbiosis of gut microbiota may play an important role in the pathogenesis of acute pancreatitis and affect prognoses, including gut microbiota structure disorder and bacterial translocation. It can also affect host metabolism and increase the production of toxic metabolites and affect the treatment of acute pancreatitis. Probiotics are live microorganisms that can give health benefits to the host when applied in sufficient quantities, which can effectively stimulate the growth and reproduction of the normal flora of the body, inhibit the overgrowth of pathogenic bacteria, and have a protective effect on the intestinal barrier function. A search of electronic databases (PubMed, EMBASE, Cochrane) has been realized to summarize the information. The paper briefly describes the concept of gut microbiota and acute pancreatitis, examines the role of gut microbiota in the development and treatment of acute pancreatitis, concludes the investigations of the therapeutic effect of probiotics for dysbiosis of gut microbiota in acute pancreatitis in order to provide a valid reference for the development of subsequent clinical strategies.
