[A new international morphologic classification of gastritis (modification of the Sydney system)].

A new international classification of gastritis retained basic principles of the Sydney system-combination in the diagnosis of etiology, topography and morphological features. This makes the diagnosis close to the nosological one. The advantage of the classification is its visual-analogous scale of evaluation of the morphological changes degree. It will ensure higher reproducibility of the morphological results and will decrease the controversies between morphologists. Subdivision of chronic atrophic gastritis into the subtypes-autoimmune (etiology) and multifocal (morphology)-is lame. Likewise, so-called peculiar forms of gastritis are not covered. Nevertheless, this modified classification may be considered as acceptable for diagnostic and research goals.
