Qing Qing, the baby girl born with a tail-like third leg and abandoned on the streets of Beijing, was discharged from hospital yesterday, one month after a successful operation. The 16-month-old toddler has now recovered from the effects of malnutrition and yesterday played happily in the arms of her adoptive mother. The extra limb growing out of her back was actually Qing Qing's undeveloped Siamese twin. Because it grew at a much faster rate than the rest of her body, the parasite limb had been depriving her of vital nutrients. The removed limb weighed more than 1.5kg, about 16 per cent of Qing Qing's body weight. Surgeons at Dongzhimen Hospital in Beijing operated on Qing Qing in August, although they found she was suffering from an incurable partial paralysis in her lower legs. Doctors say she is recovering faster than they expected. 'Besides being able to lie on her back immediately after the operation, now she can crawl, sit and her left leg can even move,' said Dr Zheng Dabin, the lead surgeon. Doctors said it was too early to say if she would be able to walk one day but they remained optimistic. 'We are hopeful that she will be able to stand by herself one day,' Dr Zheng said. Qing Qing's adoptive mother, Wang Huie, said, 'I am not good at words but my heart is filled with appreciation.' Qing Qing was found abandoned in Beijing in March and was taken by police to a child welfare home. She was soon adopted by Ms Wang - a 36-year-old farmer from a suburb of Beijing. Ms Wang took her to Dongzhimen Hospital, where the surgeons agreed to operate without charging a fee - which for an operation of such complexity would normally have amounted to 100,000 yuan (HK$94,000). Qing Qing will first return to the child welfare home, where she will receive further exercises to speed up her recovery.
