title: Intestino-gastric reflux in dogs: spontaneous, after gastrojejunostomy, and after Roux-en-Y gastrojejunostomy with various lengths of the defunctioning loop.
abstract: Intestino-gastric reflux was measured in dogs with duodenostomy and gastrostomy by using chromium-51 injected through the duodenostomy. No transpyloric reflux was demonstrated. When gastrojejunostomy was performed, a large reflux was demonstrated. After conversion of the gastrojejunostomy into a Roux-en-Y gastrojejunostomy with various lengths of the defunctioning loop, a decrease in reflux was demonstrated, significantly correlated to the length of the loop. The calculated length corresponding to no reflux was found to be 49 cm.
