Unformatted text preview: Gastroesophageal Reflux Disease (GERD) • Any symptoms or esophageal mucosal damage Any that results from reflux of gastric acid into the esophagus esophagus • Classic GERD symptoms – Heartburn (pyrosis): substernal burning discomfort – Regurgitation: bitter, acidic fluid in the mouth Regurgitation: when lying down or bending over when High Prevalence of Gastroesophageal High Reflux Symptoms 60% 50% 40% 30% 20% 10% 0% 59% 19.8% Weekly Monthly Frequency of heartburn and/or regurgitation Locke et al. Gastroenterology 1997;112:1148. Important Reasons to Diagnose and Treat GERD GERD • Negative impact on health-related quality of life 1 • Risk factor for esophageal adenocarcinoma2 1. 2.

Pathophysiology of Extraesophageal GERD GERD Symptoms of Complicated GERD Symptoms • Dysphagia – Difficulty swallowing: food sticks or hangs up • Odynophagia – Retrosternal pain with swallowing • Bleeding When to Perform Diagnostic Tests When • • • • • • Uncertain diagnosis Atypical symptoms Symptoms associated with complications Inadequate response to therapy Inadequate Recurrent symptoms Prior to anti-reflux surgery Diagnostic Tests for GERD Diagnostic • • • • Barium swallow Endoscopy Ambulatory pH monitoring Esophageal manometry Barium Swallow Barium • Useful first diagnostic test for Useful patients with dysphagia patients – – – – Stricture (location, length) Mass (location, length) Bird’s beak Hiatal hernia (size, type) • Limitations Limitations – Detailed mucosal exam for erosive Detailed esophagitis, Barrett’s esophagus esophagitis, Endoscopy Endoscopy • Indications for endoscopy Indications – – – – Alarm symptoms Empiric therapy failure Preoperative evaluation Detection of Barrett’s Detection esophagus esophagus Ambulatory 24 hr. pH Monitoring Ambulatory • Physiologic study • Quantify reflux in Quantify proximal/distal esophagus esophagus – % time pH < 4 – DeMeester score • Symptom correlation Ambulatory 24 hr. pH Monitoring Ambulatory Normal GERD Wireless, Catheter-Free Esophageal pH Monitoring Potential Advantages • Improved patient comfort and acceptance comfort • Continued normal work, activities and diet study activities • Longer reporting periods possible (48 hours) possible • Maintain constant probe position relative to SCJ position Esophageal Manometry Esophageal Limited role in GERD Limited • Assess LES pressure, Assess location and relaxation location – Assist placement of 24 hr.
