title: [Controversial nature of the concept of concomitant gastroenterological diseases and tactics of their management].
abstract: Problems of a combination of diseases are urgent for every patient suffering from a gastroenterological pathology. The physician meets here not only one disease but always a combination of pathological disorders. This phenomenon is based on the intercommunication of alimentary organs being involved concomitantly in the pathological process. Concomitant diseases (sometimes called "coexistent") are cases of detection of a simultaneous disorder of two and more alimentary organs, concurrent course of two diseases and (in most cases) appearance of a new complex of symptoms. Furthermore, in contrast to the complication following exactly after the main disease, in a combination of diseases it is not always possible to establish the sequence in which organs are involved in the pathological process and the mechanism with the help of which one organ is involved in the pathological process in each particular case.
