Endoscopic surveillance of Barrett's esophagus (BE), aiming to detect prevalent dysplasia and adenocarcinoma, followed by effective endoscopic treatment, is an integral part of the esophageal adenocarcinoma (EAC) prevention paradigm. However, several limitations such as the subtle appearance of dysplasia, sampling error (inherent in current surveillance protocols), and non-compliance with surveillance recommendations, lead to missed dysplasia and neoplasia, reducing the effectiveness of surveillance as currently practiced. Careful endoscopic assessment with high resolution white light endoscopy, dye based or electronic chromoendoscopy and comprehensive sampling of the BE mucosa, remains the cornerstone of endoscopic surveillance. Emerging innovations in this area span the gamut of more efficient sampling methods, advanced imaging tools, artificial intelligence and molecular marker powered approaches as adjuncts, to identify prevalent and predict incident dysplasia/adenocarcinoma. Development and implementation of validated quality indicators will allow additional advancement of this critical field. These approaches will hopefully enable efficient and effective cancer prevention and treatment.
