The biliary continuum: an up-to-date look at biliary tract diseases

Abstract

In  the  structure of  gastrointestinal diseases, the  pathology of  the  hepatobiliary system currently ranks second in  frequency of occurrence. The stages of diseases of the biliary system can be combined into the so-called “biliary continuum”, when one patient has a consistent development of pathogenetically related diseases of the biliary tract. The progressive course of functional motility disorders of the biliary tract gradually leads to the development of organic pathology, including chronic cholecystitis, the subsequent development of gallstone disease and possible postcholecystectomy complications. Among the diseases of the biliary system, one of the most frequently used diagnoses is chronic cholecystitis. The development of chronic cholecystitis is associated with repeated attacks of acute inflammation or prolonged irritation of large gallstones. The clinical aspects of chronic cholecystitis and other pathologies included in the the «biliary continuum» largely depends on concomitant dyskinesia. There are several directions for the treatment of pathologies of the biliary system: diet therapy, medication, endoscopic and surgical treatment. According to the latest guidelines, the most important direction in modern therapy of diseases of the biliary system is the restoration of the motility of the biliary tract and the normalization of the physicochemical properties of bile. The central place in the treatment of diseases of the “biliary continuum” is given to antispasmodic drugs. The administration of antispasmodics is recommended in order to relieve biliary pain and dyspeptic symptoms caused by spasm of smooth muscles, as well as to control the inflammatory process due to a decrease in the release of pro-inflammatory substances. This article describes in detail the importance of the recovery of the biliary tract motor activity and the improvement of the physico-chemical properties of bile acids.
