[Comparative experimental physiopathological evaluation of Roux-en-Y biliary shunt and choledocho-duodenal anastomosis with an interposed jejunal loop in dogs].

The authors compare in an experimental study two biliary tract reconstructive procedures in dogs: Roux-en-Y hepatico-jejuno-stomy and hepatico-jejunoduodenoplasty. The former causes in increase of plasma gastrin and insulin and moreover a decrease of duodenal pH after alimentary stimules, whereas the latter, preserving biliary flux through the duodenum doesn't alter such parameters, and therefore should be preferred.
