title: [Reflux-preventing gastric resection. An animal experiment study].
abstract: In 30 pigs the prevention of duodenogastric reflux following distal gastrectomy through different types of jejunal transposition or Roux-en-Y-gastroenterostomy was studied. The reflux was measured by determination of the intragastric amounts of bile acids and lysolecithin, and by the total number of glycerophosphatids. After distal gastrectomy and proximal selective vagotomy, isoperistaltic jejunal segments of different lengths were transposed between gastric remnant and duodenum. The reflux was normalized by 25-cm segments. Shorter segments led to no significant decrease of the reflux. The jejunal invagination of additional isoperistaltic valve did not have a significant effect. The same protection as from 25-cm segments was obtained by Roux-en-Y-gastrojejunostomy. The role of the duodenogastric reflux following gastrectomy for the gastric mucosa is disucssed. The necessity of the reparation of the pyloric function is shown.
