Management of Mid-Epigastric Pain

Diagnostic Approach

The American Gastroenterological Association recommends starting empirical high-dose proton pump inhibitor therapy with omeprazole 20-40 mg once daily before meals for 4-8 weeks, while simultaneously testing for H. pylori using breath or stool testing, as this presentation most likely represents functional dyspepsia or peptic ulcer disease 1, 2
Obtain an ECG within 10 minutes to exclude myocardial infarction, which can present atypically with isolated epigastric pain, especially in women, diabetics, and elderly patients, with mortality rates of 10-20% if missed 3
Measure serial cardiac troponins at 0 and 6 hours to definitively exclude acute coronary syndrome 3
Check vital signs for tachycardia ≥110 bpm, fever ≥38°C, or hypotension, which predict perforation or sepsis with high specificity 3, 4

Order baseline laboratory tests, including complete blood count to assess for anemia, serum electrolytes and glucose, liver and renal function tests, and C-reactive protein and serum lactate if any concern for inflammatory or ischemic process 1, 3, 4, 6
Test for H. pylori using breath or stool testing, which has higher specificity than serology, as part of the "test and treat" strategy, which ranks first in reducing symptoms at 12 months (RR 0.89; 95% CI 0.78-1.0) 4

Initiate omeprazole 20-40 mg once daily before meals for 4-8 weeks, with healing rates of 80-90% for duodenal ulcers and 70-80% for gastric ulcers 3, 4
If H. pylori testing is positive, treat with triple therapy, including omeprazole 20 mg + Amoxicillin 1000 mg + Clarithromycin 500 mg, all twice daily for 10 days 4
If no response after 2-4 weeks of PPI therapy, switch drug class or increase PPI dosing 4

Age-based and symptom-based criteria for endoscopy, including age ≥55 years with treatment-resistant dyspepsia, age ≥40 years from high-risk area or with family history of gastroesophageal malignancy, and any age with alarm features, such as weight loss, anemia, dysphagia, persistent vomiting, or hematemesis 1, 3, 6

Smoking cessation is recommended, as smoking is a risk factor for postprandial distress syndrome 1

Reassess at 4 weeks, and if symptoms persist despite adequate PPI trial and negative H. pylori, consider endoscopy regardless of age 1, 6
