A 48-year-old woman from Mumbai presents with a 6-week history of postprandial epigastric pain and early satiety. She denies vomiting or weight loss. She has been taking ibuprofen regularly for rheumatoid arthritis for the past 2 years. On examination, she is normotensive (BP 128/82 mmHg) and has mild epigastric tenderness. Laboratory tests show haemoglobin 11.8 g/dL (normal MCV), normal liver function, and negative H. pylori serology. Upper GI endoscopy shows a 2 cm ulcer on the lesser curve of the stomach with clean base and no active bleeding. What is the most appropriate management?

Explanation

## Clinical Scenario Analysis This is a **chronic NSAID-induced gastric ulcer with clean base** — a Forrest III lesion (low immediate rebleeding risk) but requiring aggressive acid suppression and NSAID withdrawal to promote healing. ### Key Diagnostic Features **High-Yield:** The triad of: 1. **NSAID exposure** (ibuprofen × 2 years for RA) 2. **Negative H. pylori serology** (excludes infectious aetiology) 3. **Clean-base ulcer on endoscopy** (Forrest III — no active bleeding or visible vessel) Confirms NSAID-induced gastric ulcer without active bleeding. ### Healing Timeline & PPI Dosing **Key Point:** Gastric ulcers heal slower than duodenal ulcers (8–12 weeks vs. 4–6 weeks) due to: - Reduced mucosal blood flow in gastric antrum - Delayed epithelial regeneration - Continued acid exposure if NSAID not withdrawn | Ulcer Type | Healing Time | PPI Dose | Duration | |---|---|---|---| | **Duodenal (clean base)** | 4–6 weeks | Omeprazole 20 mg daily | 4 weeks | | **Gastric (clean base)** | 8–12 weeks | Omeprazole 40 mg daily | 8 weeks | | **NSAID-induced (any)** | Add 4 weeks if NSAID continued | Double standard dose | Extend by 4 weeks | **Clinical Pearl:** Omeprazole 40 mg daily achieves intragastric pH >4 for >18 hours, optimal for ulcer healing. Standard 20 mg dose is insufficient for gastric ulcers. ### NSAID Withdrawal Strategy **Mnemonic: STOP-NSAID** - **S**witch to paracetamol (acetaminophen) — safest alternative for RA pain - **T**opical NSAIDs (diclofenac gel) for localized joint pain - **O**ffer selective COX-2 inhibitor (celecoxib) ONLY if NSAID absolutely essential + PPI cover - **P**roton pump inhibitor (omeprazole 40 mg) for 8 weeks minimum **Warning:** Continuing ibuprofen even with PPI cover delays healing and increases rebleeding risk. The ulcer cannot heal while the causative agent is still present. ### Management Flowchart ```mermaid flowchart TD A[NSAID-induced gastric ulcer, clean base]:::outcome --> B{Active bleeding?}:::decision B -->|Yes: Forrest Ia-Ib| C[Endoscopic haemostasis]:::action B -->|No: Forrest III| D[Medical management]:::action D --> E[Stop NSAID permanently]:::action E --> F[Switch to paracetamol/acetaminophen]:::action F --> G[Omeprazole 40 mg daily × 8 weeks]:::action G --> H[Repeat endoscopy at 8 weeks]:::decision H -->|Healed| I[Continue PPI for 4 more weeks]:::action H -->|Not healed| J[Investigate for malignancy]:::urgent I --> K[Long-term PPI if NSAID restarted]:::action ``` ### Why Repeat Endoscopy Is Mandatory **Key Point:** Gastric ulcers require **endoscopic confirmation of healing** because: - Risk of gastric malignancy (especially in patients >50 years) - Gastric ulcers can mask early gastric cancer - Repeat endoscopy with biopsy at 8 weeks is standard of care Duodenal ulcers do not require repeat endoscopy (low malignancy risk). ### Why Each Alternative Is Wrong **High-Yield Comparison:** | Option | Error | Why Wrong | |---|---|---| | **Omeprazole 20 mg + continue ibuprofen** | Inadequate dose + ongoing NSAID | Gastric ulcers need 40 mg; continuing NSAID prevents healing | | **Famotidine 20 mg BD** | H2-blocker, not PPI | H2-blockers achieve pH >4 for only 6–8 hrs; PPIs achieve >18 hrs. Healing rate 50% lower. | | **Surgical gastrectomy + vagotomy** | Unnecessary and morbid | Reserved for intractable ulcers (rare with modern PPI) or perforation. Medical management is first-line. | [cite:Harrison 21e Ch 297; KD Tripathi 8e Ch 42]
