Since 1957, doctors at CHOP have separated 23 sets of conjoined twins, more than any other hospital in the Western Hemisphere.
Conjoined twins from United States recently had a successful surgery that will now help them lead normal healthy lives just before their birthday and the parents are elated with the new development before the big celebration.
It is rare for conjoined twins to be connected at the crowns of their heads.
Each team had to monitor the conjoined twins' vital signs using green and purple tape, one color assigned to each sister, to track their separate progress.

On this edition of Capital Tonight, we had the latest on the shots that rang out during a Congressional baseball practice. The congressman said Vice President Mike Pence spoke to Barth after the incident and that "he's on the road to recovery".
The twins made it out just fine, the family is planning to eventually return home to Mooresville with their healthy baby girls.
This was the 23rd time that the Philadelphia hospital conducted surgery on conjoined twins for successful separation. Gregory Heuer and Jesse Taylor.
The surgery was done in Philadelphia and took 30 doctors and nurses to complete an 11-hour operation. However, Abby and Erin would be the hospital's first craniopagus pair.
The most critical part in separating these twins were the blood vessels which were common in the brain block of both the babies.
Last year, Children's Hospital at the Montefiore Medical Center in New York City separated Jadon and Anias McDonald after a complicated surgery.
"Finally, we divided our team into two halves, one for each of the girls, and finished the reconstruction portion of the surgery", Heuer added. Additional surgeries for both twins are likely during this process, but Heather and her husband, Riley, are expected to bring the girls back to North Carolina later this year. Heather gave birth to Erin and Abby on July 24, 2016, and each baby weighed two pounds and one ounce.
