What is the next step in managing abdominal pain in a 75-year-old male not relieved by antacids, Proton Pump Inhibitors (PPIs), and analgesics?

Immediate Endoscopy is Required

In a 75-year-old male with abdominal pain unresponsive to antacids, PPIs, and analgesics, the next step is urgent upper endoscopy to exclude malignancy, peptic ulcer disease, and other serious organic pathology. 1

Age-Based Imperative for Endoscopy

• Endoscopy is mandatory in patients over 45-50 years with dyspeptic symptoms due to the steep rise in gastric cancer incidence with age. 1
• The traditional age cutoff of 45 years should guide immediate referral, though some Western countries may use 50 years based on local gastric cancer epidemiology. 1
• At 75 years, this patient is at substantially elevated risk for gastric malignancy, making empirical therapy without visualization unacceptable. 1

Failure of Empirical Therapy Signals Need for Investigation

• When standard antisecretory therapy (PPIs) and analgesics fail to provide relief, this represents treatment-refractory symptoms requiring endoscopic evaluation to identify the underlying cause. 1
• PPIs are highly effective for acid-related disorders and functional dyspepsia, so lack of response suggests either non-acid-related pathology or serious structural disease. 1
• Continued empirical therapy in this setting only delays diagnosis and is not cost-effective. 1

Critical Alarm Features to Assess

Before endoscopy, evaluate for additional alarm symptoms that further mandate urgent investigation: 1

• Weight loss (suggests malignancy or malabsorption)
• Recurrent vomiting (suggests obstruction or gastroparesis)
• Bleeding or anemia (suggests ulcer, malignancy, or vascular lesion)
• Dysphagia (suggests esophageal or gastric outlet pathology)
• Palpable abdominal mass (suggests malignancy or inflammatory mass)

Endoscopy Timing and Preparation

• Perform endoscopy while symptoms are present and after stopping antisecretory therapy for at least one month to maximize diagnostic yield. 1
• However, given age and treatment failure, do not delay endoscopy excessively—the diagnostic imperative outweighs the benefit of medication washout. 1

What Endoscopy Will Accomplish

Upper endoscopy in this clinical scenario will: 1

• Definitively exclude or diagnose gastric/esophageal malignancy
• Identify peptic ulcer disease (which may be refractory to standard PPI dosing or have unusual causes)
• Detect erosive esophagitis, Barrett's esophagus, or gastritis patterns
• Allow tissue sampling for histology (including H. pylori testing, eosinophilic gastroenteropathy, or malignancy)
• Provide reassurance if normal, allowing shift to functional disorder management

If Endoscopy is Normal: Consider Functional Disorder

Only after excluding organic disease through endoscopy should functional dyspepsia management be pursued: 1, 2, 3

• Tricyclic antidepressants (amitriptyline 10 mg nightly, titrated to 30-50 mg) are the most effective second-line treatment for functional abdominal pain. 1, 2, 3
• TCAs work through noradrenaline reuptake inhibition to control visceral pain, independent of mood effects. 1
• Avoid opioids completely—they worsen gastric emptying, risk narcotic bowel syndrome, and create addiction potential without addressing visceral pain mechanisms. 1, 2, 3

Common Pitfall to Avoid

Do not continue empirical therapy or add additional medications (different PPIs, H2-blockers, prokinetics) without first obtaining endoscopic diagnosis in this elderly patient with treatment failure. 1 This approach risks missing curable malignancy during its window of resectability and violates the fundamental principle that age >45-50 years mandates visualization before prolonged empirical management.
