[Quantification of duodenogastric reflux in patients with different gastric resections (author's transl)].

The duodenogastric reflux was measured quantitatively in patients with classic gastric resections (Billroth I, Billroth II with and without enteroanastomosis) as well as in patients without gastric operations. A total of 43 patients with gastric resection and 6 without gastric operation were studied. Patients operated according to B II without Braun's enteroanastomosis (n = 10) had a bile reflux of 50.4 +/- 4.1% (SEM) during the study. Patients having been operated according to B II- and Braun's-enteroanastomosis (n = 15) and those having undergone B I-operation (n = 17) had a duodenogastric reflux of 21.5 +/- 3.7% (SEM) and 23.1 +/- 3.5% (SEM), respectively. In 6 control subjects without gastric operation bile reflux into the stomach averaged 0.5 +/- 0.4% (SEM).
