AIM:To address the diagnostic value of the regular arrangement of collecting venules (RAC) among old age patients. METHODS: A total of 390 consecutive patients whoseHelicobacter pylori (H. pylori ) status was known and who received upper gastrointestinal endoscopy, were retrospectively studied for the presence or absence of RAC as well as gastric mucosal atrophy. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of RAC to detect normal gastric mucosa were assessed and were compared among two different age groups of patients. RESULTS:The mean age ± standard deviation (SD) of included patients (n = 390), was 62.9 ± 13 years. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of RAC to detect normal gastric mucosa were 91.7%, 66.1%, 18.8%, 99% and 68.1% respectively. Although the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of RAC among patients < 60 years (n = 139) was 94.7%, 71.2%, 46.2%, 98.1%and 76.1%, respectively, it was 80%, 64.3%, 5.1%, 93% and 64.6%, respectively, among patients ≥ 60 years (n = 251). Younger Patients (< 60 years), have highly significant rates of RAC sensitivity, positive predictive value, and accuracy (P ≤ 0.001, ≤ 0.001 and ≤ 0.02, respectively). Older patients had highly significant rates of H. pylori infection and gastric mucosal atrophy (P ≤ 0.01). CONCLUSION:Although RAC is a valuable sign for real-time identification of normal gastric mucosa, its accuracy seems to be affected by the patient's age.

“…However, high-resolution magnifying endoscopy without chromoendoscopy also appears superior to standard endoscopy, allowing great accuracy for the diagnosis of H. pylori gastritis, intestinal metaplasia, and dysplasia [66,67]. No comparative study of magnification with or without chromoendoscopy has been made for the diagnosis of these lesions, despite the suggestion of Tanaka et al that enhanced magnification chromoendoscopy with acetic acid is superior to conventional magnification endoscopy and indigo carmine chromoendoscopy [65].…”

Atrophic gastritis, intestinal metaplasia, and epithelial dysplasia of the stomach are common and are associated with an increased risk for gastric cancer. In the absence of guidelines, there is wide disparity in the management of patients with these premalignant conditions. The European Society of Gastrointestinal Endoscopy, the European Helicobacter Study Group, the European Society of Pathology, and the Sociedade Portuguesa de Endoscopia Digestiva have therefore combined efforts to develop evidence-based guidelines on the management of patients with precancerous conditions and lesions of the stomach. A multidisciplinary group of 63 experts from 24 countries developed these recommendations by means of repeat online voting and a meeting in June 2011 in Porto, Portugal. The recommendations emphasize the increased cancer risk in patients with gastric atrophy and metaplasia and the need for adequate staging in the case of high-grade dysplasia, and they focus on treatment and surveillance indications and methods.

Comparison of High Resolution Magnifying Endoscopy and Standard Videoendoscopy for the Diagnosis of Helicobacter pylori Gastritis in Routine Clinical Practice: A Prospective Study

Abstract: High resolution magnifying is superior to standard endoscopy for the diagnosis of H. pylori gastritis, and identification of specific histopathologic features such as atrophy and intestinal metaplasia seems possible.
