In my experience, qualifying the pattern and extent of gastritis can provide more guidance on subsequent management. The endoscopist should assess and document the visual pattern (atrophic, hemorrhagic, nodular, ulcerated, etc.) and the extent (corpus, antrum, along lesser curvature, diffuse, etc.) of gastritis, because these findings could impact the need for additional biopsies and endoscopic follow-up. Any evidence of significant bile reflux into the antrum seen during endoscopy should also be noted.
