Oesophageal changes in oral submucous fibrosis using fibreoptic endoscopy--a pilot study

Thirty patients with oral submucous fibrosis (OSMF) underwent fibreoptic upper G.I. endoscopy and oesophageal biopsy from 20 cms to see if any correlation is found between visual and histological changes in OSMF and oesophageal mucosa. On endoscopy, the colour of oesophageal mucosa was normal in 28 and whitish pale in 2 cases. On endoscopy mucosa felt stiff and fibrotic in 19, leathery in 4, firm/gritty in 2 and normal in 5 cases. The biopsies were difficult to take in most cases yielding small tissue samples on repeated attempts. On histology most of the samples consisted of only a few layers of hyperplastic epithelium with lamina propria and submucosa being absent in all samples. Good correlation was found between the grade of OSMF and oesophageal changes seen on endoscopy.
