[Duodenogastric reflux following vagotomy with and without pyloroplasty (author's transl)].

Intragastric concentrations of bile acids, lysolecithin, 14C-bile acids, pH-value, bacterial growth and gastric mucosa histology were analysed in 47 patients following selective proximal vagotomy with and without pyloroplasty. Without pyloroplasty there were normal amounts of lysolecithin, bile acids and 14C-marked bile acids. Following pyloroplasty (Heineke-Mikulicz and Jabouly) the reflux values were 2 to 4 times higher. This increase of reflux after pyloroplasty was only one fifth of that following gastric resection. Only 20% of the vagotomized stomachs showed a bacterial contamination, an atrophic gastritis could be observed in 20% of the pyloroplasty-patients. The results demonstrate, that in selective proximal vagotomy there is no, in combination with pyloroplasty only a slight reflux gastritis.
