BACKGROUND: histopathologic identification of atrophy and metaplasia is decisive to stop the way of gastritis?carcinoma in patients with chronic gastritis.
OBJECTIVE: to compare diagnostic concordance between Sidney system and the operative Link on Gastritis Assessment (OLGA) system.
METHODS: 120 consecutive biopsies were analyzed by general pathologists according to the Sidney system. All of them were evaluated by a second pathologist who used OLGA System. We employed kappa index to evaluate diagnostic concordance between the classifications.
RESULTS: the clinical picture includes dyspepsia (94 %), abdominal pain (50 %), gastroesophageal reflux (30 %), bleed of the upper digestive system (24 %), and presence of Helicobacter pylori (47.5 %). Four were diagnosed as atrophy by Sidney system and 26 cases with atrophy by OLGA system. The concordance between two classifications systems was too low (p = 0.05).
CONCLUSIONS: the atrophy diagnosis, between systems, had low concordance. The description of metaplastic atrophy in the OLGA system represents the only one difference. The non-metaplastic atrophy is the same for both classifications. Therefore, the general pathologist should include this evaluation more consistently using OLGA system.
