胃窦炎 中国就医指南

Antral gastritis is a localized form of chronic gastritis characterized by inflammation predominantly confined to the gastric antrum—the lower third of the stomach that connects to the pylorus and regulates gastric emptying. Unlike pangastritis or fundic-predominant gastritis, antral gastritis spares the acid-producing fundus and corpus in early stages, preserving basal acid secretion while often disrupting gastrin regulation and mucosal defense mechanisms. Pathogenesis centers on persistent mucosal injury from Helicobacter pylori infection—present in over 80% of cases—triggering chronic neutrophilic and lymphocytic infiltration, oxidative stress, and progressive glandular atrophy. Other contributors include long-term NSAID use, bile reflux (especially post-cholecystectomy or with impaired pyloric function), autoimmune mechanisms (less common than in corpus-predominant disease), and lifestyle factors such as smoking, heavy alcohol consumption, and chronic psychological stress. Epidemiologically, antral gastritis affects an estimated 30–50% of adults globally, with higher prevalence in low- and middle-income countries due to endemic H. pylori transmission. In China, seroprevalence exceeds 55% in adults over age 40, and antral-predominant patterns account for ~60% of biopsy-confirmed chronic gastritis cases. Risk factors include age >45 years, rural residence, crowded living conditions during childhood, untreated H. pylori infection, habitual NSAID or aspirin use, and comorbidities like type 2 diabetes and metabolic syndrome. While often asymptomatic in early stages, patients commonly report epigastric discomfort, early satiety, postprandial bloating, nausea, and intermittent dull pain—symptoms frequently mistaken for functional dyspepsia. Untreated, antral gastritis may progress to atrophic gastritis, intestinal metaplasia, and—over decades—elevate gastric cancer risk, particularly when combined with H. pylori virulence factors (CagA+/VacA+ strains) and host genetic susceptibility (e.g., IL-1β polymorphisms). Quality of life impact is substantial: patients report reduced work productivity, dietary restrictions (e.g., avoidance of spicy, acidic, or fatty foods), sleep disruption due to nocturnal discomfort, and heightened anxiety about malignancy—especially following endoscopic diagnosis with biopsy findings of metaplasia or dysplasia. Psychological burden is underrecognized; studies show 25–35% of patients meet criteria for health-related anxiety or mild depression linked to symptom chronicity and diagnostic uncertainty. Early diagnosis via high-definition upper endoscopy with targeted antral biopsies—and confirmation of H. pylori status via rapid urease test, histology, or stool antigen assay—is critical. Management focuses not only on symptom relief but also on mucosal healing, eradication of modifiable drivers, and surveillance stratification based on histopathological severity (e.g., OLGA/OLGIM staging).
