[Absorption of amino acids in patients after partial gastrectomy (B II) and truncal vagotomy with pyloroplasty or antrectomy (author's transl)].

: After surgery for gastric or duodenal ulcer the resorption of amino acids is changed due to alteration of morphology and function of stomach, bile system, pancreas and small bowel. We used the stable isotope labelled amino acid 15N-glycine in patients after partial gastrectomy (B II), truncal vagotomy with pylorplasty as well as antrectomy and in healthy persons. It could be shown that in contrast to the control group the absorption of the amino acid in the surgical group took place more rapid and more intensive.
