What is the appropriate evaluation and management for a patient presenting with epigastric tenderness?

Evaluation and Management of Epigastric Tenderness

The appropriate evaluation and management of epigastric tenderness should follow a systematic approach that prioritizes ruling out serious conditions while efficiently diagnosing and treating the most likely causes based on clinical presentation.

Initial Diagnostic Approach

Key Differential Diagnosis

Epigastric tenderness can result from multiple etiologies, including:

• Gastroesophageal reflux disease (GERD)
• Esophagitis
• Peptic ulcer disease (PUD)
• Gastritis
• Duodenal ulcer disease
• Gastric cancer
• Hiatal hernia
• Acute pancreatitis
• Myocardial infarction
• Acute aortic syndromes 1

Essential History Elements

• Timing and nature of pain (burning, gnawing, sharp)
• Relationship to meals
• Associated symptoms:
  • Heartburn or regurgitation (suggests GERD)
  • Dysphagia (suggests esophageal disease)
  • Nausea/vomiting (suggests gastritis, PUD)
  • Hematemesis (suggests bleeding PUD or gastritis)
  • Weight loss (concerning for malignancy)
• Medication use, particularly NSAIDs
• H. pylori risk factors
• Previous history of gastric/duodenal disease 1

Physical Examination Focus

• Location and degree of tenderness
• Presence of guarding or rebound tenderness
• Signs of peritoneal irritation
• Abdominal distension 1

Diagnostic Testing Algorithm

Step 1: Initial Laboratory Tests

• Complete blood count
• Liver function tests
• Serum lipase (if pancreatitis suspected)
• H. pylori testing (breath or stool test) 1, 2

Step 2: Risk Stratification for Endoscopy

Urgent endoscopy (2-week wait) indicated for:

• Dyspepsia with weight loss if age ≥25 years
• Dyspepsia and age >40 years from high gastric cancer risk area or with family history of gastroesophageal malignancy 1

Consider non-urgent endoscopy for:

• Treatment-resistant dyspepsia if age ≥25 years 1

Step 3: Imaging Based on Clinical Suspicion

For suspected acid reflux, esophagitis, gastritis, PUD, or duodenal ulcer:

• Upper GI series (double-contrast) is appropriate for initial evaluation 1

For suspected gastric cancer:

• CT abdomen and pelvis with IV contrast or upper GI series 1

For suspected hiatal hernia:

• Biphasic esophagram, single-contrast esophagram, or upper GI series 1

For suspected pancreatitis:

• Serum lipase >3 times upper limit of normal is diagnostic
• Contrast-enhanced CT after 72 hours from symptom onset if needed 2

Management Algorithm

Step 1: Test and Treat for H. pylori

• If H. pylori positive, treat with appropriate eradication therapy:
  • Triple therapy: Omeprazole 20 mg + Amoxicillin 1000 mg + Clarithromycin 500 mg, all twice daily for 10 days
  • Dual therapy: Omeprazole 40 mg once daily + Clarithromycin 500 mg three times daily for 14 days 3

Step 2: Symptom-Based Treatment

For predominant epigastric pain (ulcer-like dyspepsia):

• Full-dose PPI therapy (e.g., omeprazole 20 mg once daily) is the first-line treatment for patients with ulcer-like dyspepsia 1, 3
• For active duodenal ulcer: Omeprazole 20 mg once daily for 4 weeks
• For active benign gastric ulcer: Omeprazole 40 mg once daily for 4-8 weeks 3

For GERD symptoms:

• Omeprazole 20 mg once daily for up to 4 weeks
• For erosive esophagitis: Omeprazole 20 mg once daily for 4-8 weeks 3

For dysmotility-like symptoms (fullness, bloating, early satiety):

• Consider prokinetic agents 1

Step 3: Follow-up and Maintenance

• If symptoms resolve with initial therapy, consider trial of withdrawal
• For recurrent symptoms, repeat successful therapy or consider on-demand treatment
• For maintenance of healing of erosive esophagitis: Omeprazole 20 mg once daily 1, 3

Special Considerations

When to Suspect Serious Pathology

• Alarm features requiring urgent evaluation:
  • Weight loss
  • Persistent vomiting
  • Progressive dysphagia
  • Gastrointestinal bleeding
  • Iron deficiency anemia
  • Palpable mass
  • Age >55 years with new-onset symptoms 1

Common Pitfalls to Avoid

1. Misdiagnosing cardiac pain as gastric pain - Always consider cardiac causes in patients with risk factors
2. Overlooking pancreatic causes - Check lipase in patients with severe epigastric pain
3. Missing biliary pathology - Consider ultrasound for suspected biliary colic 4
4. Failing to recognize HELLP syndrome in pregnant women - Pregnant patients with epigastric pain require immediate hematological investigation 5
5. Overreliance on imaging without thorough clinical assessment - CT and ultrasound should supplement, not replace, clinical judgment 6

By following this systematic approach, clinicians can efficiently diagnose and manage patients with epigastric tenderness while minimizing the risk of missing serious pathology.
