[Incidence of stress ulcer and secretion of gastric juice following truncal and selective vagotomy].
In rats development of stress ulcers by immobilization is accompanied by elevated pH, reduced amount of gastric juice, and by this with decreased amount of acid. Consequently, the acid factor has no primary importance for the development of stress ulcer. Truncal vagotomy, selective proximal vagotomy, and selective antral vagotomy result in reducing the acid secretion at elevated pH value and increased juice amount, and in a decreased ulcer rate. Greatest certainty to prevent stress ulcer gives the truncal vagotomy, whereas there is a poor effect after antral vagotomy.
