Abstract
BACKGROUND AND OBJECTIVE: This narrative review discusses Barrett's esophagus management in the context of perceived deficiencies or controversies. Barrett's adenocarcinoma incidence has not clearly been impacted by Barrett's screening and surveillance. METHODS: The following report was derived from articles using PubMed and Google searches. The search was concentrated on Barrett's esophagus screening and management guidelines. KEY CONTENT AND FINDINGS: Comprehensive literature searches that highlight potential deficiencies or controversies regarding the current approach to Barrett's esophagus were employed. Esophageal adenocarcinoma incidence is rapidly increasing and this malignancy usually presents in an advanced and unresectable state. This is despite the significant expenditure of resources and time in endoscopic screening for and surveillance of Barrett's esophagus. Thus, more widespread screening for Barrett's esophagus may be considered. In addition, there are apparent inefficiencies and precision lack in the performance of endoscopic surveillance. This relates mainly to the lack of endoscopic cues for dysplasia. On the other hand, relatively low-risk subjects have frequent screening or surveillance procedures increasing cost. Lastly, endoscopic ablation for Barrett's with dysplasia has moderately good efficacy, especially for eradication of dysplasia, but mandates intensive post-therapy endoscopic surveillance. There is some concern for subsurface development of advanced Barrett's lesions. Fortunately, there is intense research in improving Barrett's esophagus diagnosis and treatment. Our narrative review will delineate deficiencies and potential measures to remedy them. CONCLUSIONS: In conclusion, screening for Barrett's esophagus and surveillance in Barrett's subjects have minimal established benefits, but proposed changes in screening practices and innovations in Barrett's esophagus endoscopic surveillance and dysplasia therapy have great promise.
