[Stimulation of H+ secretion and serum gastrin by intra-operative electrical vagal stimulation before and after proximal selective vagotomy (author's transl)].
H+ secretion and gastrin concentration were measured before and after electric vagal stimulation during proximal selective vagotomy in 29 patients with duodenal ulcers. Before vagotomy, H+ secretion and serum gastrin concentration significantly rose after stimulation, while after complete vagotomy H+ secretion remained below basal values, although serum gastrin concentration was significantly increased. These results indicate that without vagal innervation there is no gastrin secretion within physiological levels. The method is suitable for testing the completeness of the vagotomy, the results not agreeing with those obtained by pressure measurements (Burge's method).
