胃溃疡 中国就医指南

A gastric ulcer is a circumscribed mucosal defect in the stomach lining that extends through the muscularis mucosae into the submucosa or deeper layers. Unlike superficial erosions, gastric ulcers involve structural disruption of the gastric wall and carry higher risks of complications including bleeding, perforation, gastric outlet obstruction, and malignant transformation. Pathogenesis centers on an imbalance between aggressive factors—primarily Helicobacter pylori infection (present in 70–90% of cases), nonsteroidal anti-inflammatory drug (NSAID) use, excessive gastric acid secretion, and smoking—and defensive mechanisms such as mucus-bicarbonate barrier integrity, mucosal blood flow, prostaglandin synthesis, and epithelial restitution. H. pylori induces chronic active gastritis, disrupts tight junctions, increases IL-8-mediated neutrophil infiltration, and upregulates acid production via ghrelin and histamine pathways. NSAIDs inhibit cyclooxygenase-1 (COX-1), reducing protective prostaglandins (PGE2 and PGI2) critical for mucus secretion and microvascular perfusion. Epidemiologically, gastric ulcers affect approximately 5–10% of the global population during their lifetime, with incidence rising sharply after age 50. In China, prevalence is estimated at 4.5–6.2% among adults undergoing upper endoscopy for dyspepsia, with male-to-female ratio of ~1.8:1. Key modifiable risk factors include chronic NSAID or low-dose aspirin use, smoking (doubles ulcer risk and impairs healing), heavy alcohol consumption, psychological stress (via vagal hyperactivity and impaired mucosal defense), and untreated H. pylori infection. Non-modifiable risks include advanced age, prior peptic ulcer disease, and genetic polymorphisms affecting interleukin-1β and TNF-α expression. Gastric ulcers significantly impair quality of life: patients commonly report recurrent epigastric pain (often burning or gnawing, worsened by fasting and relieved by food/antacids), early satiety, nausea, postprandial bloating, and fear of eating—leading to weight loss, sleep disruption, work absenteeism, and heightened anxiety about malignancy. Untreated or recurrent ulcers correlate with reduced physical functioning scores (SF-36), increased depression prevalence (up to 32%), and diminished social participation. With timely diagnosis—typically via esophagogastroduodenoscopy (EGD) with biopsy—and evidence-based therapy, >90% of uncomplicated ulcers heal within 6–8 weeks, and recurrence rates drop below 10% with sustained H. pylori eradication and NSAID de-escalation.
