SINGAPORE, May 23(Xinhuanet)-- The separated twin girls from Indonesia are in stable condition, according to doctors at Singapore's Gleneagles Hospital on Monday.

The 15-month-old sisters have been fed with water and glucose orally, said doctors, who predicted that the girls will be out of danger and be discharged in a month if their situation remains stable one week after the operation.

Anjeli and Anggi, who were joined at the abdomen and hip bone, underwent a successful 10-hour separation surgery on Saturday.

The ventilator was taken off from Anjeli on Monday, the weaker of the twins with a hole in her heart, while Anggi was able to breathe on her own a day ago.

Both of them reacted to their parents and doctors on Sunday after they came back to consciousness, doctors said.

Though each of the sisters has only one leg after the surgery, doctors said that they can resort to crutches or artificial legs to move around.

Doctors also found with surprise that the girls have their separate sets of reproductive organs and kidney during the operation on Saturday, which added some comfort to the happy parents.

A rich businessman from Indonesian city of Medan, the hometown of the poor family, will pay for the whole medical treatment worth 450,000 Singapore dollars(about 272,000 US dollars).

This is the fourth separation surgery conducted in the island state.

Doctors successfully separated a pair of 11-month-old girls from Nepal, who were fused at the head, in a marathon operation lasting four days in April 2001.

However, the head-joined Iranian twin women were not as lucky as the Nepalese. They died at the age of 29 on July 8, 2003, from massive blood loss after a 52-hour operation at the Raffles Hospital in Singapore.

Up to 28 specialists, together with 100 assistants performed the operation, which re-routed their shared brain vein.

Two weeks after the tragedy, doctors from the same hospital made the separation of a pair of four-month-old twin sisters from South Korea a success, who were connected at the lower back. Enditem
