Functional disorders of the gastrointestinal tract (FD GIT) are the most relevant area of ​​modern gastroenterology and the area of ​​intersection of interests of practical and fundamental medicine. This trend is attributable to the high prevalence of FD GIT in the global population, reaching 15-25% of the adult population of developed countries, as well as the inadequacy of data on all pathogenetic links underlying the development of this pathology. In order to systematize the accumulated data and develop algorithms for diagnosing FD GIT and treating patients with this pathology, an expert group was organized more than 20 years ago, and the creation of the first consensus recommendations known as the «Rome Criteria» or «Rome Consensus» was result of its activity. Since that time, the definition of the FD GIT, the principles of their classification and therapeutic and diagnostic tactics have evolved based on new data of both fundamental and clinical medicine. The present article considers the modern concepts of etiology, pathogenesis, diagnostic criteria and options of treatment of functional disorders of the biliary tract.
