Core Tip
Core Tip: An open question in the clinical management of gastritis is whether the current Updated Sydney system is appropriate for classification. It appears to have become obsolete in view of the increasing knowledge on atrophic gastritis. Thus, we propose a new classification system for atrophic gastritis based on morphological criteria, named as the Updated Kimura-Takemoto classification system. This new system correctly reflects the severity of histological atrophy in the gastric mucosa, exceeding the Updated Sydney system in accuracy of detecting gastric atrophy. Moreover, it has higher sensitivity for detecting mild, moderate and severe atrophic gastritis.
