Helicobacter pylori (H. pylori) infection can cause gastric dysplasia and cancer via chronic inflammatory changes in the gastric mucosa that may lead to gastric atrophy and intestinal metaplasia. Many epidemiologic studies have demonstrated the prophylactic effects of H. pylori eradication on gastric cancer, and H. pylori eradication after endoscopic resection of early gastric cancer may prevent the occurrence of metachronous gastric cancer or dysplasia. Despite insufficient data on the effect of H. pylori eradication on gastric dysplasia and cancer before endoscopic resection, some studies have shown that H. pylori eradication can induce the regression or slow the progression of some gastric dysplasia. Therefore, eradication therapy before endoscopic resection may be effective in selected cases of low-grade dysplasia. However, endoscopic resection should be considered as the first-line treatment in high-grade dysplasia or early gastric cancer owing to the potential morphologic changes to some dysplasia or cancer that can be incurred by the eradication process, which may make it difficult to perform a subsequent endoscopic procedure.

Antimicrobial resistance is a growing problem in the eradication of Helicobacter pylori. A combination therapy with proton pump inhibitor, clarithromycin, and amoxicillin is recommended as the first-line treatment regimen in Korea. However, the eradication rate with a standard triple therapy has been unsatisfactory in the last decade, and one of the main reasons for treatment failure is the increasing prevalence of strains resistant to antimicrobials. Therefore, comprehensive and detailed information on antimicrobial resistance is mandatory to optimize the strategy of eradication treatment. The antimicrobial resistance of H. pylori is reported to vary according to study population, geographical region, and test methods. In this review, the prevalence of antimicrobial resistance of H. pylori isolates in Korea is summarized on the basis of recent studies.

In Korea, the number of screening endoscopies to detect early stage gastric neoplasms has increased exponentially following the active implementation of the National Cancer Screening Program.Current Concepts: Endoscopic treatment, including endoscopic mucosal resection and endoscopic submucosal dissection, is recognized as a minimally invasive treatment method with low morbidity and mortality for gastric dysplasia or early gastric cancer. Owing to improvement in the detection of early gastric cancer and advances in techniques, cases of endoscopic resection have increased and indications have been expanded. Endoscopic resection can preserve gastric function with excellent maintenance of the patient’s quality of life, and previous studies have shown better long-term follow-up outcomes compared to those with surgery. However, the fundamental limitation of endoscopic procedures is that gastric lymph-node dissection is not possible using endoscopic resection.Discussion and Conclusion: Although the usefulness of endoscopic resection is proven for tumors with a very low risk of lymph-node metastasis, follow-up examination using endoscopy and computed tomography should be performed for at least 5 years after curative resection of early gastric cancer.
