Abstract: Computed tomographic (CT) findings involving the biliary intestinal limb of a Roux-en-Y choledochojejunostomy may be ambiguous because oral agents frequently do not reflux into that limb. We describe 2 cases where antegrade biliary intestinal limb opacification by intravenous CT cholangiography in the left lateral decubitus position obviated the need for biopsy of an apparent enlarging mass in the biliary intestinal limb. We conclude that CT cholangiography may help clarify the status of a Roux-en-Y choledochojejunostomy.
