Abstract：
Gastritis is a disease characterized by inflammation of the gastric mucosa. It is very common and has various classification systems such as the updated Sydney system. As there is a lot of evidence that Helicobacter pylori infection is associated with the development of gastric cancer and that gastric cancer can be prevented by eradication, H. pylori gastritis has been emphasized recently. The incidence rate of gastric cancer in Korea is the highest in the world, and due to the spread of screening endoscopy, atrophic gastritis and intestinal metaplasia are commonly diagnosed in the general population. However, there have been no clinical guidelines developed in Korea for these lesions. Therefore, this clinical guideline has been developed by the Korean College of Helicobacter and Upper Gastrointestinal Research for important topics that are frequently encountered in clinical situations related to gastritis. Evidence-based guidelines were developed through systematic review and de novo processes, and eight recommendations were made for eight key questions. This guideline needs to be periodically revised according to the needs of clinical practice or as important evidence about this issue is published in the future.
摘要：
胃炎是一种以胃粘膜炎症为特征的疾病。它非常常见，并且具有各种分类系统，例如更新的悉尼系统。由于有大量的证据表明幽门螺杆菌感染与胃癌的发生发展有关,胃癌可以通过根除来预防,幽门螺杆菌胃炎最近被强调。韩国的胃癌发病率是世界上最高的,由于筛查内窥镜检查的普及，萎缩性胃炎和肠上皮化生通常在一般人群中诊断。然而,韩国尚未针对这些病变制定临床指南.因此,本临床指南是由韩国幽门螺杆菌和上消化道研究学院针对胃炎相关临床中经常遇到的重要课题制定的.循证指南是通过系统审查和从头过程制定的，并就八个关键问题提出了八项建议。本指南需要根据临床实践的需要或将来发布有关此问题的重要证据进行定期修订。
