title: Bone mineral analysis and X-ray examination of the bone in patients with biliary atresia.
abstract: Investigations of bone mineral content, X-ray of the radius and ulna and serum biochemical analysis were performed in 10 children with biliary atresia (B.A.) and 150 healthy children. The patients were classified into 2 groups, namely; group A, comprised of 5 patients whose postoperative courses went well, and group B, comprised of 5 patients who developed various degrees of liver disturbance postoperatively. The ratio of bone mineral content (BMC) to bone width (BW) (BMC/BW) increased in accordance with age in the healthy children and the patients of group A, but was relatively slow in the patients of group B. Signs of rickets were found on the X-rays of 4 of the 10 patients, while serum levels of calcium and 25-OH-vitamin D in the group B patients were significantly lower than those in the group A patients or healthy children. Serum levels of alkaline phosphatase (Alp) fluctuated, but serum Alp was elevated in all the patients with rickets.
