Abstract
The promoting effect of partial gastrectomy in the development of cancer in the remnant stomach was examined in rats after oral administration of N-methyl-N′-nitro-N-nitrosoguanidine, using various surgical approaches. The incidence with which cancer developed in the remnant stomach following gastrectomy was lower than the incidence of gastric cancer in the entire glandular stomach. The incidence of cancer in the remnant stomach following Billroth II procedure according to Mayo’s method, was higher than the incidence of cancer with other reconstructive methods as well as the corresponding area in the nonresected groups. There was a correlation between the incidence of cancer and the total bile acid concentration in the remnant stomach.
