[Gastric acid secretion by vagal electrostimulation (author's transl)]

In the operative verification of vagotomy, electrical stimulation of the vagus nerves with the study of pH should seem to be a reliable method. On the basis of an experiment in the cat, the authors emphasise the effectiveness of electrical stimulation of gastric acid secretion, confirmed by 16 clinical cases. Stimulation of the proximal end of the divided right nerve may be used to detect a nervous strand arising above the level of the section and to confirm the completeness of left vagotomy.
