title: [Significance of pancreatic and duodenal secretions for the protection of gastrointestinal anastomoses following stomach resection--an animal experiment study].
abstract: The consequences of deviation of pancreatic juice and bile after gastric resection were studied in an experimental animal model in 66 rats. After hemigastrectomy and Billroth I resp. Billroth II anastomoses papilla vateri was transplanted into a deep jejunal limb in a B I and a B II group each. Absence of alkaline secretions of Papilla vateri was followed by a marked increase in acidity in the gastric remnant and connected intestine. Especially in the Billroth II operated stomach we found an increased ulcer risk under these circumstances. With additional histamine-stimulation frequency of ulcer was 75% in Billroth II but only 33% in Billroth I animals. When alkaline reflux was preserved the ulcer rate ranged from 15 to 40% in all groups. These results confirmed the protective property of postresectional reflux for the integrity of anastomoses after gastric resection. The increased resistance of Billroth I anastomoses in spite of deficient luminal acid buffers could be explained by the mucus-bicarbonate-barrier of the duodenal mucosa.
