THE PROGNOSTIC-SIGNIFICANCE OF BILIARY BILIRUBIN CONJUGATES IN BILIARY ATRESIA

Nine patients with biliary atresia (BA) were investigated from the asp ect of biliary bilirubin conjugates. They were classified arbitrarily into the good prognostic group in which jaundice disappeared (serum to tal bilirubin equal or below 1.0 mg/dl), and the poor prognostic group in which persistent jaundice was observed for more than 12 months. Th e ratio of biliary bilirubin diconjugate (BDC) increased in all patien ts of the two groups by the first month after operation. Although ther e was no significant difference in daily bilirubin excretion within 1- 3 postoperative days, the BDC ratio in the good prognostic group was s ignificantly higher than that in the poor prognostic group (p < 0.01). The study indicated that the ratio of BDC was an early prognostic det erminant of BA patients. The prognosis of BA patients was much influen ced by the ability of bilirubin conjugation in the early postoperative days.
