A 50-year old white male presents for surveillance endoscopy for Barrett's esophagus. He was diagnosed with Barrett's esophagus 3 years ago after he underwent upper endoscopy for longstanding heartburn. Biopsies from the esophagus then showed intestinal metaplasia with no dysplasia. Currently, upper endoscopy reveals columnar mucosa in the distal 6 cm of the esophagus with no discernible mucosal nodularity. Biopsies show high grade dysplasia. He has no other complaints or comorbidities and physical examination is unremarkable.
