  Intestinal microecology is established from birth and is constantly changing
until homeostasis is reached. Intestinal microecology is involved in the immune
inflammatory response of the intestine and regulates the intestinal barrier
function. The imbalance of intestinal microecology is closely related to the
occurrence and development of digestive system diseases. In some
gastrointestinal diseases related to pediatric surgery, intestinal microecology
and its metabolites undergo a series of changes, which can provide a certain
basis for the diagnosis of diseases. The continuous development of
microecological agents and fecal microbiota transplantation technology has
provided a new means for its clinical treatment. We review the relationship
between pathogenesis, diagnosis and treatment of pediatric surgery-related
gastrointestinal diseases and intestinal microecology, in order to provide new
ideas and methods for clinical diagnosis, treatment and research.
