Aim:
To identify the mucosal patterns of Helicobacter pylori (H. pylori)-related gastritis in the gastric corpus using standard endoscopy and to evaluate their reproducibility.
Methods:
A total of 112 consecutive patients underwent upper gastrointestinal endoscopy. The endoscopists classified the endoscopic findings into 4 patterns. In the second part of the study, 90 images were shown to 3 endoscopists in order to evaluate the inter-observer and intra-observer variability in image assessment.
Results:
The mucosal patterns of the gastric body were categorized into 4 types. Type 1 pattern was defined as cleft-like appearance, type 2 as regular arrangement of red dots, type 3 pattern as the mosaic mucosal pattern and type 4 pattern as the mosaic pattern with a focal area of hyperemia. Type 1 and type 2 mucosal patterns were statistically significant in predicting H. pylori-negative status as compared with other mucosal types (chi(2) = 12.79 and 61.25 respectively, P < 0.01). Type 3 and type 4 mucosal patterns were statistically significant in predicting a H. pylori-positive status as compared with other mucosal types (chi(2) = 21.22 and 11.02 respectively, P < 0.01). Furthermore, the sensitivity, specificity, positive and negative predictive values of type 3 plus type 4 patterns for predicting H. pylori-positive gastric mucosa were 100%, 86%, 94%, and 100%, respectively. The mean kappa values for inter- and intra-observer agreement in assessing the various endoscopic patterns were 0.808 (95% CI, 0.678-0.938) and 0.826 (95% CI, 0.727-0.925) respectively.
Conclusion:
Our study suggests that mucosal patterns in H. pylori-infected gastric mucosa without atrophy can be reliably identified using standard endoscopy in the gastric corpus.

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

01:17Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
