Background/Aims: In the Helicobacter pylori (H. Pylori)-negative normal stomach, collecting venules are visible over all the gastric body as numerous minute points evaluated with standard endoscopy. This finding was termed regular arrangement of collecting venules (RAC), and its absence suggests H. pylori gastritis. The aim of this study was to evaluate the correlation between the RAC and rapid urease test. Methods: Two hundred sixty three consecutive adults undergoing upper digestive endoscopy and rapid urease test were included. The lesser curvature of the lower corpus was evaluated for the RAC pattern using a standard endoscope and different hemoglobin index. Two biopsies from the lesser curvature of the antrum and the greater curvature of the body were collected for rapid urease test. Results: H. pylori were detected in 51.3% (135/263) patients. Of the 57 patients with H. pylori-negative normal stomachs 53 patients (93%) had RAC. As a determinant of the normal stomach without H. pylori infection, the presence of RAC had 41.4% sensitivity, 97.0% specificity, 93.0% positive predictive value and 63.6% negative predictive value. Conclusions: RAC-positive finding by standard endoscopy showed high positive predictive value and specificity of H. pylori-negative normal stomach. RAC-positive finding by standard endoscopy could be an useful finding to predict H. pylori negativity. (Korean J Gastroenterol 2011;58:252-257)
