Barrett’s oesophagus and columnar metaplasia: saying what we mean

To the Editor: I wish Professor Carr the very best in his attempt to eliminate the somewhat confusing term “Barrett’s oesophagus” from the literature.1
Changing well entrenched medical nomenclature is difficult, however. I tried to do this with “microscopic colitis” 10 years ago2 but was not successful. After all, I argued, we do not speak of “microscopic bronchitis” or “microscopic salpingitis” — so why should we have the term microscopic colitis?
It is nonetheless pleasing to note that the definition of microscopic colitis has tightened up over the past 10 years,3 and I think this may be a more realistic aim for Professor Carr with the term Barrett’s oesophagus.
Admittedly, the two entities are not perfectly analogous, as, unlike microscopic colitis, Barrett’s oesophagus is classically associated with abnormally coloured mucosa. However, in both entities, the endoscopist usually takes biopsies from endoscopically flat mucosa, specifically looking for the disease in question.
I am not sure I can see myself in 10 years’ time looking down someone’s oesophagus and saying, “I think there may be some columnar metaplasia down there. I wonder if there is some intestinal metaplasia as well?” Maybe this would be a good conversation opener in the halls of the pathology department, but certainly not in the endoscopy suite! I think I will still be saying, “That looks like Barrett’s, but we will need to take biopsies to make sure”.
