Background/objectives: To investigate the demographic features, primary endoscopic findings, and the status of Helicobacter Pylori (H. pylori) infection of the enrolled subjects who underwent upper gastrointestinal endoscopy (UGIE) in the Zanzibar Archipelago, Tanzania. Methods: Between December 2013 and October 2021, a total of 3146 eligible participants were finally recruited in present retrospective cohort. Demographic information and endoscopic findings of each participant was retrieved. H. pylori infection was confirmed by rapid-urease test of gastric antral and body biopsies at endoscopy. Results: Among the recruited subjects, 1691 (53.76%) are females, remaining 1455 (46.24%) are males. The median age of this retrospective cohort was 40 years ranging from 8 to 97 years. The common identified endoscopic findings included gastro-duodenitis,normal endoscopic finding, peptic ulcer disease (PUD), esophagitis, esophagogastric varices, esophageal and gastric cancer, respectively. After adjustment for sex and age, a significant risk of gastric and/or duodenal ulcer (OR, 2.51; 95% CI, 1.82–3.48, P<0.001) and gastric cancer (OR, 3.49; 95% CI, 1.27–9.58, P=0.015) in H. pylori positive group was observed. Stratified analysis indicated a significant relationship between duodenal ulcer with younger age (adjusted OR, 0.98; 95% CI, 0.97–0.99, p = 0.002), and the presence of H. pylori (OR, 2.01; 95% CI, 1.12-3.91, p= 0.021). Conclusions: The present study revealed that gastro-duodenitis, PUD, and normal finding are the most common endoscopic diagnoses in Zanzibar. The presence of H. pylori is significantly associated with duodenal ulcer and gastric cancer. Keywords: Upper gastrointestinal endoscopy; Helicobacter Pylori; Zanzibar.
