The regular arrangement of collecting venules (RAC) and the Kimura-Takemoto classification of atrophic change (KTC) are simple criteria that can reliably predict or rule out a Helicobacter pylori infection. These endoscopic features should be given attention by Western endoscopists and can be easily used to rule out such infections.
Background The regular arrangement of collecting venules (RAC) and the Kimura-Takemoto classification of atrophic change (KTC) are simple and easy-to-use criteria which have been shown to reliably predict or rule out a Helicobacter pylori infection of the stomach. Although these features have been investigated extensively in Asia, their significance in the West has not been evaluated. Methods In a series of 200 consecutive gastroscopic examinations (single examiner, single center), the presence or absence of RAC and the KTC grade (open type vs closed type) were recorded prospectively. Helicobacter pylori infection was defined as a positive histology or a positive rapid urease test. Furthermore, multivariate analysis of endoscopic predictors of H. pylori infection based on the Kyoto classification of gastritis was performed. Results Two hundred patients were examined of which 57 had a H. pylori infection (28%). Both RAC and KTC had excellent negative predictive values of about 90% and sensitivity values of up to 85%. In multivariate analysis, atrophic change and diffuse redness without RAC were significantly associated with H. pylori infection. Conclusion Regular arrangement of collecting venules and KTC are simple endoscopic features which should be given attention by Western endoscopists and can be easily used to rule out a H. pylori infection of the stomach.
