Abstract
This chapter outlines the pathogenesis of Barrett’s esophagus and its prevention.
The development of Barrett’s esophagus involves metaplasia of the normal squamous esophageal epithelium to mucus-secreting columnar epithelium. It has been proposed to represent a two-step process, whereby the initial transformation from squamous to columnar mucosa occurs relatively quickly, over a few years, while the second step, which involves the development of goblet cells, which are indicative of intestinal metaplasia, occurs relatively slowly – over 5–10 years. The etiological factors proposed include a variety of genetic, environmental, and pharmacological factors. There are several studies which have suggested that there are a number of putative mutations and genome abnormalities implicated, which are covered in this chapter.
The precise mechanisms and risk factors for the development of Barrett’s esophagus are not entirely understood. We covered the current theories on lifestyle and pharmacological and surgical strategies aimed at reducing or preventing the progression of Barrett’s metaplasia.
