[A consensus on Helicobacter pylori and gastroduodenal pathology].

The current debate involving Helicobacter pylori (H.p.) and its potential role as an etiological factor for some digestive diseases, as well as the recent discussion through different mass media of this bacterium, including the American N.I.H. Consensus, have lead to the discussion of the H.p. problem, in order to clarify its real importance in acid-related diseases. Thus we want, as gastroenterologists, to give an overview of the current status, so as to facilitate the general practitioner work when confronted with gastrointestinal diseases, particularly related to H.p. Our purpose is to provide a critical and objective view regarding the implications of H.p. infection, and explain when treatment is needed and how this treatment should be accomplished.
