Background/aims. The incidence of adenocarcinoma of the oesophagus has incr
eased. Its major risk factor is Barrett's epithelium of which the sine qua
non is microscopically diagnosed intestinal metaplasia. Short segment Barre
tt's epithelium may often be overlooked during routine endoscopy. In routin
e biopsies taken from normal-appearing mucosa of the distal oesophagus, the
reported rates of short segment Barrett's epithelium in the distal oesopha
gus reached 36%. We compared these rates with the results obtained in a com
munity hospital in Israel.
Methods. Consecutive patients undergoing oesophagogastroduodenoscopy were e
nrolled. Biopsy specimens taken from cardia, oesophagogastric junction and
2 cm above the oesophagogastric junction were stained with haematoxylin & e
osin and Alcian blue.
Results, There were 112 study patients (mean age +/- SD 48.9 +/- 8.3 years,
51.8% males). Nine (8.04%) patients had intestinal metaplasia (according t
o specimen from 2 cm above oesophagogastric junction), and symptoms of gast
ro-oesophageal reflux were found in only four (44.4% of them. Of these nine
patients, six (6.66%) had normal-appearing mucosa and three (3.33%) had ma
croscopic Barrett's epithelium. Alcian blue staining revealed two patients
with intestinal metaplasia that haematoxylin & eosin staining had missed.
Conclusion, We found an 8% prevalence of intestinal metaplasia compared to
18-36% reported in the literature. We also determined that the added advant
age of routine biopsy was 5.4%.
