A 52-year-old man from Delhi presents with a 3-year history of heartburn occurring 2–3 times per week, worse after heavy meals and lying down at night. He reports regurgitation of food and water brash. Physical examination is unremarkable. Upper endoscopy performed 6 months ago showed no Barrett's oesophagus or erosive changes. He has tried antacids and lifestyle modifications without sustained relief. What is the most appropriate next step in management?

Explanation

## Clinical Diagnosis and Management Approach **Key Point:** This patient has typical GERD symptoms (heartburn, regurgitation) with a normal endoscopy. The diagnosis is clinical, not endoscopic, and does not require pH monitoring for confirmation in the presence of classic symptoms. ### Rationale for Standard-Dose PPI Therapy The patient meets criteria for pharmacological treatment: - Frequent symptoms (2–3 times/week) affecting quality of life - Failed trial of lifestyle modification and antacids - No evidence of complicated disease (no Barrett's, erosions, or stricture) - Normal endoscopy rules out alternative diagnoses **High-Yield:** In uncomplicated GERD with typical symptoms and normal endoscopy, empirical PPI therapy is both diagnostic and therapeutic. Standard-dose PPIs (e.g., omeprazole 20 mg or pantoprazole 40 mg once daily) achieve healing and symptom relief in >80% of patients within 4–8 weeks [cite:Harrison 21e Ch 287]. ### Why Not the Other Investigations/Interventions? | Modality | Indication | Why Not Here | |----------|-----------|---------------| | **24-h pH monitoring** | Atypical symptoms, refractory GERD, or to confirm diagnosis when clinical picture is unclear | Patient has classic GERD; diagnosis is already established clinically | | **Laparoscopic fundoplication** | Refractory GERD despite optimal PPI, or patient preference to avoid long-term medication | Premature; patient has not yet had adequate trial of PPI | | **H2-receptor antagonist** | Mild, infrequent symptoms; less effective than PPIs for moderate–severe disease | Inferior efficacy; patient has frequent, bothersome symptoms | **Clinical Pearl:** A positive response to a 4-week trial of high-dose PPI (symptom relief in >70% of cases) further confirms GERD diagnosis and guides long-term management. ## Management Algorithm ```mermaid flowchart TD A[GERD symptoms + normal endoscopy]:::outcome --> B{Symptom frequency & severity?}:::decision B -->|Mild, infrequent| C[Lifestyle modification + antacids]:::action B -->|Moderate-severe, frequent| D[Empirical PPI standard dose × 4-8 weeks]:::action D --> E{Symptom relief?}:::decision E -->|Yes| F[Continue PPI; consider step-down]:::action E -->|No| G[High-dose PPI or pH monitoring]:::action G --> H{Refractory?}:::decision H -->|Yes| I[Consider fundoplication or EGD for complications]:::action ``` **Mnemonic:** **STEP** for GERD management = **S**tandard PPI dose first → **T**rial for 4–8 weeks → **E**valuate response → **P**roceed to escalation or maintenance based on outcome.
