Abstract
The incidence of esophageal cancer has increased dramatically in the Western population in the last 2 decades. In 1975, about three fourths of the esophageal neoplasms were squamous cell carcinomas and the remainder were adenocarcinomas. During the last 2 to 3 decades, this pattern has changed dramatically and the incidence of squamous cell carcinomas has declined while the incidence of adenocarcinomas has increased. The reason for this dramatic increase is not clear, but gastro esophageal reflux disease, obesity and Barrett's esophagus have been identified as risk factors. High grade dysplasia in Barrett's esophagus is a premalignant condition which can progress to invasive adenocarcinoma. In this article, we discuss the natural history of high grade dysplasia (HGD), difficulties in the diagnosis, the incidence of adenocarcinoma in resected specimens and the surgical aspects in the treatment of HGD, including minimally invasive esophagectomy.
