A 14-MONTH-OLD girl last night became the second child in Hong Kong to receive a liver transplant using part of her father's liver. Professor Arthur Li Kwok-cheung completed the 13-hour operation at about 10.30 pm at the Prince of Wales Hospital. He said the child, whose biliary atresia (a blockage in the bile duct) had left her very small for her age, was doing extremely well despite suffering from a chest infection at the time of surgery. The operation is only the second in Asia to involve a related donor, whose liver was cut down to size for a child. The transplanted liver - half of her 41-year-old civil servant father's organ - had already begun to produce bile, he said. Earlier attempts to find a donor had failed.
