No results posted yet for this study

Summary

This prospective multicenter study investigates the added benefit of incisura biopsy to correct identification of patients with high-risk chronic gastritis (OLGA stages III-IV). It compares a biopsy protocol with and without a single incisura biopsy in a non-inferiority design. Anonymized photo and videodocumentation according to institution practices will constitute a databank for lesion recognition, quality improvement, and potential AI development.
