Evaluating the Accuracy of the Endoscopic ABC Classification System in Diagnosing Helicobacter pylori-Infected Gastritis.

Aims: Evaluating the accuracy of the modified Endoscopic ABC (Endo ABC) classification with an electronic endoscopy with narrow band imaging without magnification in diagnosing Helicobacter pylori (H. pylori)-infected gastritis.

Methods: A total of 576 patients were enrolled and they underwent modified Endo ABC.

[Analysis of the gray-zone cutoff values of new serum Helicobacter pylori antibody kits using latex immunoassay].

The serum Helicobacter pylori titers are good markers for population-based H. pylori screening and treatment programs because the tests used to estimate these titers are noninvasive, inexpensive, and convenient. However, the reference range of 3-10U/mL, which is used as a standard in commercially available serum H.

[Cost cut of cancer by a shift in gastric cancer risk screening (serum ABC classification) combined with eradication of H. pylori, and H. pylori test and treatment program in young people].

We estimated the costs and the benefits of a shift strategy of gastric cancer risk screening (ABC stratification) with H. pylori eradication, and H. pylori test and treatment program in young people, comparing with the current barium gastrograph.
