The effect of truncal vagotomy on the induction of intestinal metaplasia and atypical glandular hyperplasia by intragastric instillation of 5% NaOH solution was investigated in Wistar rats. Truncal vagotomy resulted in significant increases in the incidences and numbers of intestinal metaplasia and atypical glandular hyperplasias in experimental week 52. Histological examinations show that unlike goblet cell metaplasia and mild atypical glandular hyperplasia in the sham-operated rats, intestinal metaplasia without Paneth cells and moderate atypical glandular hyperplasia were more frequent in rats treated with NaOH solution and vagotomy. These findings indicate that the promoting effect of truncal vagotomy on gastric carcinogenesis may be related to its enhanced effect on induction of intestinal metaplasia and atypical glandular hyperplasia.
