(2017)

Additional Information

Abstract

Dr. Shaheen's issue of Gastrointestinal Endoscopy Clinics of North America addresses the current thinking and clinical decision making surrounding endoscopy for Barrett's Esophagus. Expert authors have contributed articles on the following topics: The Troublesome Epidemiology of Barrett’s Esophagus and Esophageal Adenocarcinoma; Who Deserves Endoscopic Screening for Esophageal Neoplasia; Alternatives to Traditional per oral Endoscopy for Screening; Effectiveness and Cost-Effectiveness of Endoscopic Screening and Surveillance; The Role of Adjunct Imaging in Endoscopic Detection of Dysplasia; Beyond Dysplasia Grade: The Role of Biomarkers in Stratifying Risk; Management of Nodular Neoplasia in Barrett’s Esophagus: Endoscopic Mucosal Resection and Endoscopic Submucosal Dissection; EUS and Management of Superficial Esophageal Neoplasia; Radiofrequency Ablation of Barrett’s Esophagus: Patient Selection, Preparation, and Performance; Radiofrequency Ablation of Barrett’s Esophagus: Efficacy, Complications, and Durability; Cryotherapy of Barrett’s Esophagus; Care of the Post-Ablation Patient: Surveillance, Acid Suppression and Treatment of Recurrence; and Surgical Management of Superficial Esophageal Neoplasia. Readers will come away with the knowledge to diagnose and treat neoplasia and Barrett's Esophagus using the latest techniques.
