Diagnosis of Helicobacter pylori Infection by the Arrangement of Collecting Venules Using White Light Endoscopy: Evaluation of Interobserver Agreement.

Background: Regular arrangement of collecting venules (RAC) in gastric mucosa accurately identifies patients without Helicobacter pylori (H pylori) infection. The aim of our study was to evaluate the reproducibility of RAC using white light endoscopy without magnification, in a European country, and to assess the impact of proton pump inhibitors (PPIs).

Methods: A multicenter prospective study with image capture of the distal lesser gastric curvature and gastric biopsies was performed.

Frequency and clinical characteristics of early gastric cancer in comparison to advanced gastric cancer in a health area of Spain.

Introduction: Gastric cancer (GC) incidence is currently decreasing; however, survival is still low. Early GC (EGC) has better prognosis and it could be cured by endoscopic methods.

Patients And Methods: Observational study of a retrospective cohort of all patients with GC during a five-year period in a health area of Spain.

Gastric cancer missed at esophagogastroduodenoscopy in a well-defined Spanish population.

Background: Although esophagogastroduodenoscopy (EGD) is the standard procedure for the diagnosis of gastric cancer (GC), some GCs are missed. There are no published data on the missed rate of GC in Spain.

Aims: To determine the frequency and characteristics of missed GCs and assess the quality of the EGD in a specific population with GC.
