[Oral glucose tolerance test with a mixture of oligosaccharides after partial gastrectomy (author's transl)].

Fourteen non-diabetic male patients undergoing partial gastrectomy for ulcer disease were investigated with oral glucose tolerance test using a 100 g mixture of oligosaccharides. Partial gastrectomy had been performed between 1 and 3 years ago. Compared to seven healthy male control subjects, patients had significant higher blood glucose levels at 30 and 60 min and a more rapid descent, so that at 120 and 180 min no differences were found between patients and control subjects. With the usual criteria (blood glucose levels at 120 and 180 min) the non-diabetic patients with partial gastrectomy showed normal test results.
