title: Management of Barrett's Esophagus.
abstract: Barrett's esophagus is a pathologic change of the normal squamous epithelium of the esophagus to specialized columnar metaplasia. Barrett's esophagus is a result of prolonged exposure of the esophagus to gastroduodenal refluxate. Although Barrett's itself is not symptomatic,  and, in fact, patients with Barrett's esophagus may be completely asymptomatic, it does identify patients at higher risk of developing esophageal adenocarcinoma. Traditionally, antireflux surgery was reserved for patients with symptoms, because it was believed that antireflux surgery  did not eliminate Barrett's esophagus and reduce cancer risk. Rationale for the treatment of Barrett's esophagus beyond treating symptoms of gastroesophageal reflux disease stems from the hope to decrease, if not eliminate, the risk of adenocarcinoma. Treatment options ranged from  medical acid suppression without surveillance to resection. Ablation, particularly endoscopic radiofrequency ablation, has become the standard of care for Barrett's esophagus with high-grade dysplasia. It role in nondysplastic or low-grade dysplastic Barrett's is less clear. Combined  endoscopic mucosal resection with ablation is effective in nodular high-grade Barrett's esophagus. Resection should be reserved for patients with persistent high-grade dysplasia despite multiple attempts at endoscopic ablation or resection or for patients with evidence of carcinoma.
