Approximately 1% of the gastric neoplasies are nowadays associated with the infection of the gastric mucus by Helicobacter pylori. In view of the fact that its prevalency is very high and that it does not exist any objective and universal estimator in its diagnosis but the digestive endoscopy and biopsy, it is proposed, in candidate patients for a digestive endoscopy, although the explorer observes an endoscopic normality, to carry out, systematically, and antral biopsy for its subsequent diagnosis, treatment and prevention both of the gastric pathology and the infection by Helicobacter pylori.

Some authors do not accept as valid the clinical diagnosis of gastritis, due to the latter being mainly an anatomical-pathological term. Others, however, argue that such diagnosis may be establish through a correct anamnesis. A cross-sectional study of a hundred and fifty patients undergoing fibrosgastroscopy with antral biopsy and anamnesis, as well as clinical exploration in accordance with specific protocols, has been conducted. We have concluded that there does not exist as symptomatology associated to a concrete pathology, despite the presence of certain symptoms as, for example, the pain, that may be related with certain pathologies (14/20 of those developing H.H.E.D., 22/34 of those developing UB and 7/10 of those developing neoplasia). We also inferred that many of the patients (46/50) with endoscopic and histological normal findings (20/23), present as many as or more symptoms than those with pathological findings. This symptomatology may be due to a somatic disorder that could be hiding the process.

We have conducted a blind cross-selectional study with 150 consecutive patients undergoing fibrogastroscopy and biopsy of the antral mucosa. The endoscopic sensitivity for the diagnosis of the several types of gastritis, is low (63%), although this technique is highly sensitive for other types of pathology. Consequently, we conclude that, in all endoscopic explorations, at least one biopsy of the antral mucosa must be done, given the anatomopathological definition of gastritis. In addition, the clinical use of this term should be restricted to the histologically demonstrated cases.
