[Verifying the function of hepaticojejunostomies by scintigraphy of the bile ducts].

Thirty six hepatobiliary scintigraphies with 99mTc-Dimethyl IDA were performed in thirty patients with an hepaticojejunostomy one month to ten years after surgery. Twenty patients underwent surgery for biliary disease and ten for duodenal or pancreatic disease. In most cases (twenty three), the radionuclide study has been systematically performed to assess the scintigraphic pattern of a normal hepaticojejunostomy. In seven cases this pattern was abnormal. Four times the biliary enteric anastomosis was involved. Three times it showed an abnormal liver morphology. After an hepaticojejunostomy, hepatobiliary scintigraphy seems to be the only examination providing dynamic information for the biliary enteric anastomosis and the intestinal loop. But it sometimes is difficult to analyse in all cases, it must be the screening test in patients when symptoms occur after hepaticojejunostomy; but a percutaneous transhepatic cholangiogram cannot always be avoided.
