In order to observe the absorption of the fat solube vitamine afer operative treatment of the congenital biliary dilation(CBD),the plasma fat soluble vitamin A,D and E were determined in 57 cases of CBD at the postoperative stage and 51 cases of normal children as control.The normal values of vitamin A,D and E was 576.25±170.93ng/ml,13.21±2.20ng/ml and 7.34±1.96ng/ml respectively in control group versus 501.59±120.64ng/ml, 11.66±1.81ng/ml and 6.16±1.18ng/ml respectively in the postoperative group of CBD.The differences were significant for a long period of about 10 years,and gradually disappear after that to approach or near the normal level.Therefor,the radical operation of CBD may affect the absorption of the fat soluble vitamins.
