title: Current Concepts in Treatment of Barrett's Esophagus With and Without Dysplasia.
abstract: Around 10-15% of patients with gastroesophageal reflux disease will develop Barrett's esophagus (BE). The development of novel endoscopic modalities has changed the management of BE in the last decade.
  
  
  
  The aim of this study was to review the current evidence for the treatment of BE with and without dysplasia.
  
  
  
  In patients with BE without dysplasia, antireflux surgery should not be suggested as a modality to prevent the malignant transformation of BE, but its indications should be the same as for other patients with gastroesophageal reflux. Endoscopic surveillance at intervals of 3-5 years is recommended for these patients. For patients with BE with low-grade dysplasia, radiofrequency ablation (RFA) is the preferred treatment modality, while endoscopic surveillance every 12 months is an acceptable alternative in patients with life-limiting comorbidities. For most patients with BE and high-grade dysplasia, RFA is the preferred treatment strategy. Patients with intramucosal adenocarcinoma (T1a), should be treated with EMR followed by ablative therapy, in order to eradicate the remaining intestinal metaplasia. Endoscopic resection may be suitable for low-risk T1b tumors (well-differentiated, without lymphovascular invasion, and with superficial submucosal invasion); however, further data are necessary to better risk stratify this group.
  
  
  
  Patients with BE without dysplasia should undergo endoscopic surveillance every 3-5 years. Endoscopic ablative therapy (RFA) is the preferred treatment modality for dysplastic BE. Patients with T1a adenocarcinoma should be treated with EMR followed by ablative therapy. Low-risk T1b tumors may be suitable for endoscopic resection.
