[Entero-gastric reflux after distal stomach resection--an animal experiment study].

UNLABELLED: The experiments were carried out in 125 Wistar rats. The entero-gastric reflux was estimated quantitatively with reference to the bilirubin and the cholic acid (radiolabeled by C 14). The animals were submitted to distal partial gastrectomy in groups after Billroth I operation, after Billroth II operation with and without enteroanastomosis, as well as Billroth II operation with enteroanastomosis and vagotomy. RESULTS: The statistical difference was significant between Billroth I and Billroth II operation with clear smaller reflux in Billroth I. The added enteroanastomosis decreased or increased the reflux of some animals at a time. The additional vagotomy reduced the number of the anastomotic ulcer.
