Helicobacter pylori associated Chronic Gastritis and Application of Visual Analogue Scale for the Grading of the Histological Parameters in Nepal

A working party presented the Sydney System: A New Classification of Gastritis in Sydney at the World Congress of Gastroenterology in 1990 [1-6]. The discovery of Helicobater pylori by Robin Warren and Barry Marshall in 1982; was the revolution in understanding of gastritis and upper gastrointestinal disease [7]. H. pylori infection became evident as the key factor and initiator of the majority of the pathology related to gastritis and its sequelae. Since then interest in gastritis and the morphological appearances of endoscopic biopsies increased. However; H. pylori may not be the sole etiological agent in some cases where H. pylori are detected in biopsies [8,9].
