Interdisciplinary consensus RE.GA.IN.: view from the gastroenterologist and endoscopist

Chronic gastritis holds one of the leading roles in the structure of pathology of the upper gastrointestinal tract, with which practicing specialists of related specialties - gastroenterologists, therapists, endoscopists - meet on everyday basis. The up-to-date generalizing system of views on this pathology is presented in the RE.GA.IN. consensus (2024). We have highlighted and structured the most practical points of the consensus in the context of classification and characterization of the main forms of chronic gastritis, emphasized approaches to diagnosis and dynamic observation, illustrated the supporting endoscopic criteria of the disease. Moreover, we paid special attention to the description of endoscopic patterns of normal and pathological findings using modern endoscopic technologies as an integral factor of interdisciplinary interaction between clinicians and diagnosticians. In our work we tried to specifically and thoroughly address the problem of autoimmune subtype of the condition as one of the most clinically significant at the current moment, but at the same time often underestimated forms of chronic gastritis.
