title: Prevention of reflux after gastro resection in the pig.
abstract: In 48 pigs the duodenogastric reflux of bile acids and lysolecithin is studied after different types of gastroduodenostomy, jejunal interposition and Roux-Y-gastroenterostomy. The intragastric concentrations of bile acids and lysolecithin were found to be pathologically elevated after gastroduodenostomy. There was no difference between end-to-end, end-to-side or supraduodenal end-to-side anastomoses. An effective reflux prevention was possible by interposition of 25 cm of isoperistaltic jejunum or by Roux-Y. A shorter (15 cm) interposition with or without an isoperistaltic invagination valve was not sufficient in normalizing reflux amounts.
