[The functionally defective Roux Y-loop in biliodigestive anastomoses].

In comparison to common radiologic methods hepato-biliary sequential scintigraphy proves superior in the investigation of the choledocho-(hepatico-)jejunostomy Roux-en-Y. The functional behavior of the jejunal-(Roux-en-Y-) loop is demonstrated. After biliary-intestinal anastomoses, 15 healthy patients showed normal dynamic studies with unimpeded bile passage. Hypotonic loops with intrahepatic bile stasis responsible for cholangitis were seen in 2 patients. A strangulation phenomenon on the level of the mesocolon hiatus responsible for upper abdominal pain is demonstrated in one case.
