What is the best course of action for a patient with persistent gastroesophageal reflux disease (GERD) symptoms, including dysphagia, globus sensation, vomiting, and nausea, despite being on Famotidine (Histamine-2 receptor antagonist) and Omeprazole (Proton pump inhibitor), with a history of hepatomegaly with fatty infiltration and a gallbladder polyp?

Proceed with Upper Endoscopy Now

This patient has alarm symptoms (dysphagia, recurrent vomiting for 4 months) that mandate immediate upper endoscopy regardless of PPI response, and the current dual therapy with omeprazole and famotidine is not evidence-based and should be discontinued. 1

Immediate Action Required

Refer for upper endoscopy without delay. The presence of dysphagia and recurrent vomiting are alarm symptoms that require investigation to rule out esophageal cancer, stricture, or other structural pathology. 1 In a recent analysis of approximately 30,000 patients with dysphagia who underwent endoscopy, greater than 50% had important clinical findings, most commonly esophageal stricture. 1

The gastroenterologist's note questioning the need for EGD appears to have been written before fully appreciating the severity and duration of symptoms. Four months of daily vomiting with dysphagia is not a benign presentation and cannot be adequately evaluated with less invasive testing. 1

Medication Management Pending Endoscopy

Immediately discontinue famotidine. The combination of PPI plus H2-receptor antagonist is not evidence-based for routine GERD management and only increases costs and potential adverse effects. 2 Nighttime H2RAs are only recommended for patients with documented nocturnal symptoms despite adequate PPI therapy, which is not this patient's presentation. 2

Optimize omeprazole dosing. The patient is currently on omeprazole 40mg daily, which is appropriate given symptom severity. 3 However, ensure the patient is taking it 30-60 minutes before meals (not at bedtime) for optimal efficacy. 1, 3 This timing error is a common pitfall that significantly reduces PPI effectiveness. 4

Do not escalate to twice-daily PPI dosing before endoscopy. While twice-daily dosing is sometimes used for refractory symptoms, this patient has alarm features that require structural evaluation first. 1 Escalating acid suppression could mask serious pathology. 1

What the Endoscopy Should Evaluate

The endoscopy must include: 1

• Inspection for erosive esophagitis (graded according to Los Angeles classification)
• Assessment of the diaphragmatic hiatus (Hill grade of flap valve)
• Measurement of axial hiatus hernia length
• Inspection for Barrett's esophagus (with Prague classification and biopsy if present)
• Evaluation for esophageal stricture (the most common finding in patients with dysphagia) 1
• Assessment for eosinophilic esophagitis (can present with dysphagia and is often missed) 5

Post-Endoscopy Management Algorithm

If severe erosive esophagitis (LA grade C/D) or Barrett's esophagus is found:

• Continue omeprazole 20mg daily indefinitely as maintenance therapy 2
• These patients should not be considered for PPI discontinuation 2
• If esophagitis grade B or worse is found, repeat endoscopy after 8 weeks of PPI therapy to ensure healing and rule out Barrett's esophagus 1

If esophageal stricture is found:

• Endoscopic dilation will likely be required 1
• Continue PPI therapy at current dose 1
• Repeated endoscopy with dilation may be needed as stricture recurrence is common 1

If endoscopy is normal or shows only mild disease (LA grade A or less):

• Perform prolonged wireless pH monitoring off PPI therapy (96-hour preferred if available) to confirm or rule out GERD 1
• This is critical because the patient has been on long-term PPI without objective confirmation of GERD 1
• If pH monitoring shows physiologic acid exposure, consider functional esophageal disorders or alternative diagnoses 1

If eosinophilic esophagitis is found:

• This changes management entirely and requires different treatment (topical steroids, dietary elimination) 5

Consider Alternative Diagnoses

Given the hepatomegaly with fatty infiltration and the symptom pattern, also consider: 5

• Functional dyspepsia (nausea and epigastric pain are prominent features)
• Gastroparesis (constant nausea, vomiting, ondansetron helps nausea but not pain)
• Rumination syndrome (if vomiting occurs shortly after meals)

If endoscopy and pH monitoring are unrevealing, gastric emptying study and/or high-resolution esophageal manometry may be warranted. 5

Critical Pitfalls to Avoid

Do not continue empirical therapy without objective testing. This patient has been on PPI therapy for an extended period without endoscopic confirmation of GERD. 1 If PPI therapy is continued in a patient with unproven GERD, clinicians should evaluate appropriateness within 12 months and offer endoscopy with pH monitoring to establish appropriate use of long-term therapy. 1

Do not assume all upper GI symptoms are GERD. The prominent nausea and vomiting with only intermittent heartburn suggests this may not be typical GERD. 5 The differential diagnosis must be broadened after structural pathology is ruled out. 5

Do not add prokinetics empirically. While metoclopramide is sometimes used for GERD, it has not been proven effective for symptom control and significantly increases adverse events. 6 Prokinetics should only be considered if gastroparesis is documented. 2
