Hepatobiliary scintigraphy after hepatic portoenterostomy.

Hepatobiliary scintigraphy with 99mTc-E-HIDA was carried out in 10 patients who had undergone hepatic portoenterostomy for "non-correctable" biliary atresia. In all the patients there was an active bile flow and disappearance of jaundice, post-operatively. Elimination of 99mTc-E-HIDA from the liver was slow during the first 3 post-operative months despite active bile flow and disappearance of jaundice. The elimination rate of the radioactive agent from the liver in most long-term survivors was comparable with findings in controls.
