The esophagus isn't merely a tube for food traveling from the mouth to the stomach, it also provides an environment for bacteria to live, according to a new study by NYU School of Medicine scientists that overturns the general belief that the esophagus is free of bacteria.

Barrett's esophagus is a condition in which the normal squamous epithelium of the esophagus has been replaced by an abnormal red columnar epithelium called specialized intestinal metaplasia.
Barrett proposed that the red-colored esophagus seen in some patients was actually part of the stomach and that these patients were probably born with a short esophagus (due to the short length of the white squamous esophageal lining).
To confirm that a red lining in the esophagus is indeed specialized intestinal metaplasia, the doctor must take multiple biopsies to obtain pieces of tissue from the lining and send it to the pathology lab for histologic analysis (examination of the tissue under a microscope).
