Doctors all set to separate conjoined twins: Doctors are all set to separate conjoined twins Sita and Gita. Sita and Gita, over a year old are conjoined twins.

Residing at Bihar, these two sisters are joined at the hip. They have common urinary tract, genital/reproductive system as well as lower intestinal opening.

Having arrived at Delhi's Batra hospital, the twin sisters had to undergo numerous tests - electrolyte, kidney and liver function, and X-ray.

Dr Bagai stated that "The lower part of the twins' spines is joined externally. Neurosurgeons will have to ensure that when separating the two; neither suffers from any neurological deficits in their lower limbs post-surgery."

"We will have to separate the gut. In such children, there is a common passage for stool and a common urinary tract causing infection."

The surgery will take around 12-15 hours. Conjoined twins are rare but they are genetically identical.
