Xiao Zhengti, five, was born with a congenital liver disease meaning he needed his first transplant at just nine months old . A boy in China born with a malfunctioning liver is now looking forward to living a normal life after both of his parents donated part of their organs to save him. Xiao Zhengti, now five, was born with a  liver condition meaning he had to have his first major surgery at just nine months old, when mother Yang Haiying donated part of her liver, The People's Daily Online reports. But the boy's body rejected the organ, leading to years of trips to hospital, until father Xiao Kunqing was allowed to donate 40 per cent of his liver yesterday, leading to a full recovery. The touching story began in 2009 shortly after Xiao was born to parents from southern China's Hunan province with jaundice, which is common in babies, but doctors became concerned after it did not dissipate within a few weeks. Soon his parents noticed that he had a strange looking bulge in his stomach, and after visits to specialist Guangdong and Shanghai he was diagnosed with congenital biliary atresia. The rare condition occurs where the bile ducts around the liver swell during or immediately after birth, which can cause the tissue around them to scar. While the exact cause of bilairy artesia is unknown, it is usually fatal if left untreated, and in severe cases, such as Xiao's, it may require a transplant. The initial operation took place just nine months after he was born, but complications followed and his body rejected his mother's liver. Mother Yang Haiying (right) first donated a portion of her liver to try and save her son after being found to be a match, but his body rejected it, leading to to repeated trips to hospital for the next four years . Father Xiao Kunqing (left) was also found to be a match for the boy, but surgeons warned against a second operation, saying it carried far greater risks . However doctors eventually relented, and yesterday Mr Kunqing had 40 per cent of his liver removed and transplanted into his son . A year after the first transplant Xiao suffered 200 days of high fever, and spent the next four years moving in and out of hospital. But yesterday at the hospital in Tianjin City, eastern China, surgeons agreed to try a second operation after father Xiao Kunqing offered to donate 40 per cent of his liver. Dr Dong Chong, head of the transplant unit in Tianjin, warned the second operation would be more difficult than the first, and would carry greater risks, but the parents were determined to go ahead. The operation began at 8am on Thursday April 16th, with Mr Kunqing moved to the recovery room at around 4pm after having his liver removed. By 7.30pm Xiao Zhengti’s operation was successfully completed, and he was also moved to recovery. The operation is believed to be the first ever in China where two parents have donated the same organ in order to save their child. Surgeons now say that the operation, which took five hours to complete, was a complete success and they expect Xiao to be home within weeks when he can begin living a normal life . Medics say the operation is believe to be the first in China where two parents have donated the same organ in order to save their child . Dr Dong Chong, head of the transplant unit in Tianjin City, where the operation took place, said he expects Xiao to be home in three weeks and to lead a full and active life . Dr Dong told reporters 'The operation was extremely successful and went according to plan. 'We used microscopes for the intricate operation which normally would have taken just 2 hours but this one took 5. However it was very successful.' He added that he expects Xiao Zhengti to make a full recovery and leave hospital in around 3 weeks to enjoy a happy and active life.
