ASGE Annual GI Advanced Practice Provider Course (Virtual) (Day Two) | March 2026-GERD and Barrett’s: Diagnosis and Endoscopic Therapy

Video Transcription

Video Summary

The talk reviews gastroesophageal reflux disease (GERD) and then Barrett’s esophagus. GERD affects ~15% worldwide and ~20% in Western countries (weekly heartburn). Typical symptoms are heartburn and regurgitation, often post‑meal, with bending, or lying flat; sensitivity of symptoms is limited. Extra‑esophageal complaints (cough, hoarseness, throat clearing, asthma, globus) are common but nonspecific. GERD is multifactorial: impaired acid clearance/motility, decreased buffering, hiatal hernia or LES disruption, and delayed gastric emptying. Complications include erosive esophagitis, bleeding/iron deficiency, peptic strictures/Schatzki ring, and progression to Barrett’s and adenocarcinoma.<br /><br />Management often starts with an empiric high‑dose PPI trial, then step down. Endoscopy is recommended for alarm features (especially dysphagia), atypical symptoms, and older patients; severe esophagitis (LA C/D) should be re‑scoped after 8–12 weeks of PPI to rule out Barrett’s. Objective testing includes Bravo pH monitoring off therapy (acid only) and 24‑hour pH‑impedance (acid and non‑acid; on or off therapy depending on the question), typically preceded by manometry.<br /><br />Barrett’s requires endoscopic columnar mucosa ≥1 cm above gastric folds plus intestinal metaplasia on biopsy. Screening is suggested for chronic GERD plus risk factors. Dysplasia should be confirmed by expert pathology; endoscopic eradication (EMR for nodules, RFA for flat dysplasia; cryotherapy if RFA fails) requires repeated surveillance due to recurrence risk.
