In addition, the past decade has finally brought some progress in the care of these patients on several fronts. Endoscopic imaging, endoscopic eradication therapy, and risk stratification in the disease have all seen welcome advances during this time, after a lengthy period with little change in the care of patients with BE.

This issue of Gastrointestinal Endoscopy Clinics of North America seeks to chronicle the progress made in BE as well as the plentiful challenges that remain. We have endeavored to assemble some of the most prolific researchers and outstanding teachers from across the globe, to give a textured and comprehensive view of the care of these patients. While the technical advances in BE continue to impress, I suspect that the cognitive challenges will be those that most consume your intellectual effort as you peruse this text. Indeed, very fundamental questions like who should be screened for BE and how, who should undergo intervention to prevent neoplasia, and how should those patients be managed after intervention, all remain largely unanswered, despite extensive efforts to address them. While the uncertainty regarding best management of these patients may be daunting, they also make this area an exciting and rapidly evolving area of inquiry, which I hope will continue to attract bright minds.

I feel lucky to have as colleagues the renowned authors whose work forms the body of this issue, and I thank them for their efforts on this project. Thanks also to Kerry Holland, Nicole Congleton, and the staff at Elsevier for their tireless efforts in managing us to bring this issue together. I hope you enjoy reading the fruits of their labor, and that this work helps you better care for your patients.
