Overview
Classification and grading of Gastritis based on the Updated Sydney System emphasizes the importance of combining topographical, morphological, and etiological information into a schema that would help to generate reproducible and clinically useful diagnoses. In clinical practice, Gastritis staging is done using the OLGA (Operative Link on Gastritis Assessment) staging system for reporting gastric histology. Gastritis staging integrates the atrophy score (obtained by biopsy) and the atrophy topography (achieved through directed biopsy mapping).

- In clinical practice, Gastritis staging is done using the OLGA (Operative Link on Gastritis Assessment) staging system for reporting gastric histology. Gastritis staging integrates the atrophy score (obtained by biopsy) and the atrophy topography (achieved through directed biopsy mapping). [2] [3]
